1.2 Specified application

The electronic voltage regulator TAPCON® 230 serves forautomatic control of transformers with a motor-driven on-load tap-changer. The motor-drive mechanism receives thecorresponding control commands from the voltage regulator.With these commands, the on-load tap-changer moves tothe next position and the transformer’s voltage value isadapted to the preset desired voltage level.

To allow individual adaptation of the control system to thevarious field service conditions encountered, influencingvariables such as time delay, bandwidth, and even line-dependent and load-dependent parameters can be pro-grammed for compensation of voltage-dependent and/orcurrent-dependent limits. As a special feature, the voltageregulator is also capable of controlling parallel transformeroperation.

WARNING

This information indicates particular danger to life andhealth. Disregarding such a warning can lead to serious orfatal injury.

CAUTION

This information indicates particular danger to the equip-ment or other property of the user. Serious or fatal injurycannot be excluded.

NOTE

These notes give important information on a certainsubject.

CAUTION

Installation, electrical connection and commissioning ofthe electronic voltage regulator may only be carried outby qualified, skilled personnel and only in accordance withthese operating instructions.It is the responsibility of the user to make sure that theelectronic voltage regulator is used for the specificapplication only. For safety reasons, any unauthorized andimproperly executed works, i.e. installation, modification,alteration of the equipment, electrical connection, orcommissioning of the equipment, are forbidden withoutfirst consulting MR!The trouble-free operation of the drive, the on-load tap-changer, and the transformer may be put at risk.

1.3 Design and performance features of theTAPCON® 230

The electronic voltage regulator TAPCON® 230 is mounted ina protective housing with hinged cover and inspection win-dow. The protective housing is suitable for both flush andprojected panel mounting.The front panel contains several function keys for setting theindividual operating parameters.

Display of the operating status is achieved by a 4-line, 16-digit alphanumeric LC display and light emitting diodes.

The electronic voltage regulator is controlled by a micro-controller (see appendix, block/connection diagram).Besides a voltage transformer and a current transformer itcontains optocoupler inputs with potential separation as wellas potential-free output relay contacts.

Apart from the usual well-known, versatile and individualsetting options for the ME control system, the TAPCON® 230voltage regulator also offers the option of fast and easyparametering by introducing the innovative „Normset“function.

The term „Normset“ function stands for an automatismwhich considerably simplifies the configuration of a voltageregulator. If the desired voltage level is entered while the„Normset“ function is active, the voltage regulator willexamine the given line/network conditions and proceed toperform an automatic adaptation of all further inputs(comprised in part of the pre-parametering and standardreference values) which used to be required for customaryregulators (also refer to the standard configuration accord-ing to Sub-menu 2).

The parameters of the regulator can be set by means of a PCvia the incorporated serial interface (RS232) integrated inthe controller; the appropriate PC software will be furnishedby MR.

A load-dependent line-voltage drop, e.g. of a spur line lead-ing from the transformer to the load, can be compensatedeither by line simulation (Line Drop Compensation) or byload-current dependent increase of the voltage level (Z com-pensation).

Trouble-free operation is ensured by the regulator’s inherentundervoltage blocking, overcurrent blocking and overvoltagemonitoring.

The functions of the TAPCON® 230 voltage regulator are justabout fully compatible with those of the earlier generationsof voltage regulators.

Parallel operation follows the principles of either minimumcirculating reactive current or the Master/Follower principle.

Parallel control of two groups comprised of up to 8 userstotal is possible without the need for a supplementary devicedue to the utilization of an internal bus system.

NOTE

When voltage regulation is effected by tap transformersand voltage regulators, it is assumed that a change of thetap position results in a significant voltage change. Whengenerators feed the voltage level to be regulated, however,quite different conditions may result so that a correctregulation of the voltage cannot be guaranteed. In suchcases MR should be consulted as early as the planningstage.

4.1 Normset setting

The term „Normset“ function stands for an automatismwhich considerably simplifies the configuration of a voltageregulator. The only thing left to do for the operator whencommissioning during the Normset mode is to enter thedesired voltage level and subsequently take the device intooperation.

All other parameters required for simple voltage regulationwill be preassigned at the factory (e.g. bandwidth of ± 1 %).Should the actual value exit the set bandwidth, an appro-priate switching operation will be initiated at the on-loadtap-changer. The voltage change ensuing from the switchingoperation corresponds to the transformer’s tap voltage and ischecked for plausibility by the regulator, using the presetbandwidth. The bandwidth value is then optimised in accord-ance with the results gleaned from this check.

If the next system deviation occurs, the new bandwidth willbe used as basis, which will be rechecked and readjusted, ifnecessary.

The time parameters are handled in the same way by theregulator, which ensures optimum self-adjustment of theregulator after only a few regulating sequences.

Should the marginal conditions change, the regulator willagain optimise itself automatically.

It goes without saying that mains-specific and/or customer-specific settings such as LDC, parallel operation or positionindication can still be done in the standard mode and will betaken into consideration during determination of theoptimum parameters.

4.2 Setting the desired voltage level 1

The setting of the desired voltage level refers either to thesecondary or to the primary voltage side of the voltagetransformer connected to the TAPCON® 230.‘V’ stands for the secondary voltage which is indicated inVolt. ‘kV’ stands for the primary voltage which is indicated inKilovolt. Press the SET and function keys to set thedesired voltage level.

For increased regulating sensitivity it is also possible to setlower values, although it is highly unadvisable to go beneath60 % of the computed value. Higher values will cause adecrease in regulating sensitivity.

If the measuring-circuit voltage is altered far enough duringoperation to exceed the set bandwidth, the presignal willrespond. An output pulse will be generated according to theset delay time.

If no compensation occurs for more than 15 min, the„function monitoring“ relay will respond (see connectiondiagram). The relay will not be reset until a shortfall of thebandwidth threshold has occurred.

T1 Linear/integral

The delay time T1 can be set with linear or integral response.If a delay time with integral response „Int“ is set, the delaytime is automatically shortened according to the relation ofactual system deviation to set bandwidth, down to aminimum of 1 s (fig. 2).The desired time behavior can be set by pressing the SET and function keys.

4.4 Setting the delay time T1 or T2 (DELAY 1/DELAY 2)

The delay time starts as soon as the deviation exceeds the setbandwidth limits above or below. At the same time the cor-responding presignal arrow appears. If the deviation is stillpresent after the delay time has elapsed, an output pulse isemitted. If the deviation returns to within bandwidth limits,then the current delay time is cancelled immediately.

Delay time T2

The delay time T2 will become effective only if more than one tapchange is required for reduction of the control deviation belowthe bandwidth limit. The set delay time 2 is then valid for allconsecutive output pulses.Set the delay time T2 for a range of 1.0 … 10 s by pressing theSET and function keys.If the voltage regulator is set to PERM, it will emit a continuoussignal. If it is set to OFF, the delay time T2 will be deactivated.

4.5 Setting the overvoltage detection (U>)with automatic return control

The response threshold can be set from 101 % to 130 % ofthe desired voltage level in steps of 1 % by pressing the SETand function keys.

In the event of an overvoltage detection response, the on-load tap-changer is operated by periodic pulses to the motordrive until the overvoltage falls below the response threshold.The motor drive is controlled by periodic pulses of 1.5 sthrough the „Lower“ output relay while the set delay time re-mains inactive during this operation. At the same time thealarm signalling LED lamp responds and a signalling relay isenergized (contacts 17/18/19) as long as overvoltage is pre-sent. If the voltage regulator regulates towards a higher vol-tage than the set limit U> due to an unfavourable parame-tering (e.g. too high LDC settings), it is prevented from ex-ceeding the limit. This condition is signalled by the signallingrelay for ‘function monitoring’, after 15 minutes.

4.6 Setting the undervoltage blocking (U<)

The response threshold for undervoltage blocking can be setfrom 60 % to 100 % of the desired voltage level in steps of1 % by pressing the function keys Set and .

Undervoltage blocking prevents tap change operations inthe event of a network breakdown. The voltage regulatoroutput pulses are blocked and the alarm signalling LED lampand a signalling relay (Contacts 17/18/19) respond when themeasuring voltage falls below the set blocking value. After adelay time of approx. 10 s, the associated signalling relay isenergized and remains that way. The signalling relay doesnot respond in case of a failure of the measuring-circuitvoltage or supply voltage (< 30 V).

The overcurrent blocking response threshold can be set from50 % to 210 % (of the rated current of the current trans-former) in steps of 1 % by pressing the Set andfunction keys. Overcurrent blocking prevents tap changeoperations in the presence of overload. The voltage regula-tor output pulses are blocked and the alarm signalling LEDlamp responds when the measured current exceeds the setblocking value. At the same time the corresponding signallingrelay is energized and remains energized (contacts 17/18/19).

5.3 Easy setting of operating modes withNormset

Prior to commissioning, be sure to check the entire circuityand the measuring and operating voltage. To assess theworking mode of the voltage regulator, the use of a regis-tering device to record the regulator voltage (actual voltagelevel) is highly recommended.The related transformer should be subject to normal load.

a) Select the MANUAL operating mode at TAPCON® 230

b) Select the NORMSET function as indicated under 4.1

c) Set the Desired Voltage Level 1 as indicated under 4.2.

If you do not require a voltage display of the primary voltagein kV you may now proceed to initiate the regulator byoperating the AUTO function key.If you do require a voltage display in kV, however, pleaseproceed as follows:

d) Set the rated transformer voltage and the ratedtransformer current as indicated under 4.8.

If you wish to configure the TAPCON®230 voltage regulatorto suit your specific requirements, please proceed asindicated under 5.4.

5.4 Function tests; operational settings

Prior to commissioning, be sure to check the entire circuityand the measuring and operating voltage. To assess theworking mode of the voltage regulator, the use of aregistering device to record the regulator voltage (actualvoltage level) is highly recommended. The related transfor-mer should be subject to normal load.

a) Select the MANUAL operating mode at TAPCON® 230

b) Set the transformation ratios of the transformers asspecified under paragraph 4.8, as well as the measuringcircuit.

c) Let the measured actual voltage (= voltage from thevoltage transformer) be indicated on the display of thevoltage regulator.

d) Let the current, power, and phase angle values beindicated on the display and compare these values withthose from possibly existing service measuringinstruments. If wrong signs are indicated, reverse thepolarity of the current or voltage transformer.

e) Set the desired voltage level. By manual control of themotor drive, bring the on-load tap-changer to the serviceposition so that the desired voltage level is obtained.

f) Set the VOLTAGE LEVEL to this value.

g) Set the bandwidth „“U max“ to 1.0 %. In most cases thevoltage regulator is now in a balanced state (no presignalLED lamp lights up). Otherwise change the desired voltagelevel in steps of 0.5 V until a balanced state is reached.

h) Set the bandwidth „“U max“ dependently of the stepvoltage (see paragraph 4.3).

i) Set the delay time T1 to 20s lin. as per paragraph 4.4; bymanual control, move the on-load tap-changer towards„Raise“ by one step, the presignal LED lamp for „Lower“must come on. Set the mode of operation to „AUTO“; 20 safter the presignal lamp lights up, the voltage regulatormust control the on-load tap-changer back to its pre-vious service position. The presignal LED lamp goes out.Set the mode of operation to „MANUAL“. Repeat thecontrol procedure towards „Lower“.

Set the operating delay time T2 to 10 s. Set the mode ofoperation to „MANUAL“. By manual control, move the on-load tap-changer towards „Raise“ by two steps, the pre-signal LED lamp for „Lower“ must come on.

Set the mode of operation to „AUTO“, then 20 s after thepresignal lamp has come on, the voltage regulator mustautomatically control the on-load tap-changer back toits previous service position by one step and after further10 s by another step.

Set the delay times T1 and T2 to the desired value. If T2 isnot utilized, the „OFF“ setting will be required.

When putting the transformer into service, it is recom-mended to set the delay time T1 provisionally to 100 s.Depending on the existing operating conditions, you maywant to determine the definitive setting only after sometime of observation. For this purpose it is recommendedto register the variation of the actual voltage and thenumber of tap change operations on a day-to-day basis.If an inverse response of the voltage regulator is desired,set an integral time response for the delay time 1. In thiscase the delay time is automatically shortened inverselyproportional to the deviation.j) a

6.1.1 Parallel operation with „MinimumCirculating Reactive Current Method“

The circulating reactive current is computed from the trans-former currents and their respective phase angles. For correc-tion of the measuring circuit voltage, a voltage proportionalto the circulating reactive current is applied to self-suffi-ciently operating regulators. This correction voltage can beeither decreased or increased through adjustment of the„stability“ (see para-graph 6.1.3).

If an inadmissibly high circulating reactive current is detec-ted, all on-load tap-changers involved will be reset after only10 s, regardless of the delay time preset at the regulator.

This method is suitable for transformers of comparable out-put and uk, whether with uniform or with non-uniform stepvoltage. No information on tap position is required.

Individually set both transformers to identical voltage withthe on-load tap-changers so that both voltage regulators arein a balanced state (no presignal LED are lighting up, theindication of „d U %“ must be as low as possible, i.e. lowerthan the preset bandwidth „dU max“).

Now switch the transformers to parallel operation and enableparallel control (close contact at terminals 41 and 42, respec-tively).The voltage regulators must continue to remain in a balancedstate, the LED lamp „parallel operation“ on the front panel islighting up.Raise one of the two transformers by one voltage step andlower the other of the two transformers by one voltage step.Both regulators must continue to remain in a balanced state.Raise the setting value „CIRC.REAC.CURR.STABILITY“ of bothregulators in small steps starting with „0“ until the corres-ponding presignals appear (the regulator of the transformerwith the higher voltage step must show the tendency „lower“while the other transformer must show the tendency „raise“).Now add the setting values thus established and set theadded-up value for both regulators.Select the „Auto“ operating mode for both voltage regula-tors. Both voltage regulators must control the on-load tap-changers back into their previous service positions. The pre-signals will go out.If the previous service position cannot be achieved that way,the „CIRC.REAC.CURR. STABILITY“ setting needs to be in-creased. If the on-load tap-changers are regulating out ofsync („pumping“), this setting needs to be reduced.

NOTE

The prerequisite for the proper functioning of paralleloperation is the commissioning of the voltage regulatorsfor individual operation.

6.1.5.3 Setting the circulating reactive currentmonitoring(CIRCUL. REAC. CURR. MON. BANDWIDTH)

Switch over one of the two voltage regulators to the„Manual“ operating mode. Using the manual control, theassociated motor drive must now be reset to „Raise“ by themaximum admissible difference of the service positionsbetween the parallel operating transformers (e.g. by 1 … 2steps).Starting with the preset value of „20“, reset the blockingtowards a lower value in small steps until the message„Circulating reactive current“ appears in the status line of thedisplay (please wait 2 – 3 s between the individual steps).The bandwidth threshold of the circulating reactive currentmonitoring is reached as soon as this message appears.All voltage regulators will block all further regulating actionsand the signalling relay will respond (terminals 35/36/37).Now reset the blocking again towards a higher value untilthe message „circulating reactive current“ disappears fromthe status line of the display.

Again switch the voltage regulator back to the „Auto“operating mode. The motor drive will be automaticallycontrolled back to the original service position.Use the value established for the „Blocking“ threshold to setit for all of the other regulators.

6.2 Parallel operation according to synchro-nized tap-change operation Master/Follower

This method is suitable for transformers featuring an identi-cal rated current, identical step voltage, and an identicalnumber of service positions. The motor drive must signal thetap-change position by means of a current of 4 … 20mA(with 4mA corresponding to the lowest position and 20mAcorresponding to the highest position). Optionally the con-nection of a potentiometer contact range in the motor driveis possible in lieu of the injected current.

During parallel operation, actual voltage regulation is per-formed by one of the voltage regulators (Master function).The second voltage regulator (Follower) receives the tap-change position of the motor drive from the first regulator,for comparison with the tap-change position of its ownmotor drive. If a difference is noted, the motor drive inquestion will receive a suitable control pulse.

6.2.2 Function tests, commissioning andpreliminary settings

The voltage regulators must be set to identical operatingparameters for the desired voltage, bandwidth, time delay 1,and line compensation, if applicable.The tap position indication at the regulators must functioncorrectly.Select the „MANUAL“ operating mode at the voltage regulators.Individually set all on-load tap-changers involved in paralleloperation to identical voltage so that the voltage regulators arein a balanced state (no presignals are responding).Now switch the transformers to parallel operation and close thecontacts at terminals 41 and 42, respectively. The voltageregulators must continue to remain in a balanced state and theLED lamps „Parallel“ at the regulators must respond. Switch theFollower voltage regulator to the „AUTO“ operating mode.Use the manual control to raise the MASTER regulating unitengaged in the „MANUAL“ operating mode by one step; thefollower regulator now has to automatically drag along theassociated transformer to do the same.

During the short period while a tap position difference ispresent, the message „TAP DIFFERENCE“ will appear in the statusline of the display. If a follower regulator fails to drag along itsassociated transformer, regulating action will be blocked and asignalling relay will respond (terminals 35/36/37).

6.2.1 System configuration, settings

Lead the additional connections/terminals (see fig. 9) to theregulators.

6.2.1.1 Setting the tapping position range

Operate the SELECT key and the keys to select themenu point and set the respective lowest/highest tap posi-tions between –35 and +35 by pressing the SET andkeys. To perform a function check, set the deactivated trans-former for all positions of the entire tap position range whilechecking the position indicator.

Operate the SELECT key and the keys to select themenu point and assign the respective regulator as a Masteror a Follower by pressing the SET and keys.If both regulators were assigned as „Follower“ or „Master“during parallel operation, the regulators will be blocked (seesection 6.3 – Disturbances during parallel operation).

Since a comparison of the tap positions of the transformersjointly engaged in parallel operation is performed duringparallel operation in accordance with the principle of tap-change synchronicity (Master-Follower), it is imperative tomaintain identical position designations for all of thesetransformers, and to ensure that the „higher“ and „lower“signals will effect identical voltage changes in all thetransformers.

If this is not the case, e.g. if the „Higher“ command (highervoltage) is not equal to a higher position, it is also possible to„turn the tap direction“ within the voltage regulator.This function is activated/deactivated through operation ofthe SELECT key and the function keys.

6.3 Parallel operation with an existing parallelcontrol unit SKB 30 to the principle of„minimum circulating reactive current“

In case of an extension of a plant, it is possible to add optio-nal a communication module instead of the CAN-bus mo-dule on factory site in the voltage regulator TAPCON® 230 towork with an existing parallel control unit SKB 30.The wiring has to be done according to the schematics71481900 resp. 71482000 (see appendix).The setting for parallel control has to be done according tooperating instruction BA 117 on the parallel control unitSKB 30.

NOTE

If the communication module to SKB 30 is added, theparameters for parallel control are shown in the menus19 … 25 of the TAPCON® 230. Changes of the parametersmade here are however without effect.
