Reactive Power Controller

= Key1 = Key2 = Key3

Product descriptionIntended useThe reactive power controller Prophi together withexternal capacitor stages, serves for step by stepcontrolling of the phase shift angle cos(phi) in 50/60Hzlow voltage networks. Depending on the type of thereactive power controller Prophi, contactors or semiconductor switches can be controlled directly.Measurement and supply voltages up to 300V 50/60Hzagainst earth can be connected directly.Additionally, the following electrical quantities aremeasured and indicated:- Voltage L2-L3,- Current in L1,- Frequency,- Sum real power (Consumption/supply),- Sum reactive power (ind./cap.),- uneven current harmonic waves 1. - 19. in %,- uneven voltage harmonic waves 1. - 19. in %.The harmonic contents are related to the rated voltageor rated current.

The connection is carried out on the back side via touchproof spring power terminals.Measurement and auxiliary voltage are taken from themeasurement voltage and must be connected to thebuilding installation via a separation (switch or powerswitch) and an overcurrent protection (2A .. 10A).The current measurement is carried out via a ../5A or../1A current transformer in one outer conductor.

The relay outputs are suitable for contactor control, thetransistor outputs are provided for the control of fastswitching thyristor modules, switching at zero crossing.

Hints for maintenanceBefore delivery the device is tested in various safetychecks and marked with a seal. If the device is opened,these checks must be repeated.There is no guarantee for devices, which are openedout of the manufacturing works.

Diagr.: Connection example, power factor controller with 12 relais outputs, targetcos(phi) changeover and alarm output.

Functional descriptionMeasurementThe measurement is suited for 3 phase systems with orwithout neutral conductor for frequencies of 50Hz or60Hz. The electronical measurement system records anddigitalizes the effective values of voltage between L2and L3 and the current in L1.In each second several snap check measurements arecarried out. As the current is only measured in oneouter conductor, and the voltage only between two outerconductors, the measured values, which are related toall three outer conductors, are exact for equal loadedouter conductors only.The following electrical quantities are calculated:

Current and current harmonicsVoltage and voltage harmonicsReal power, sumApparent power,sumReactive power, sumReactive power for each stageReactive current for each stageC o s ( p h i ) ,Net frequency.

The following information can be indicated:Number of switchings of each stage,total connection time of each stage andthe inner temperature.

Prophi measures the frequency of the measurement andauxiliary voltage and shows the average over 10 seconds.

Switching of capacitor stagesProphi calculates the required reactive power to reachthe set target-cos(phi) from the current from one outerconductor and the voltage between two outer conductors.If the cos(phi) deviates from target cos(phi), externalcapacitor stages or transistor outputs are switched on oro f f .In automatic mode the capacitor stages are switched inor off, when the required reactive power is higher orequal to the smallest stage power.If the power of the first capacitor stage is three times ashigh as the measured real power, all capacitor stagesare switched off. .

Switching outputsDepending on the variety of Prophi, relay or transistoroutputs serve as switching outputs.The relay outputs are suitable for controlling contactorsand the transistor outputs can switch thyristor modules,that switch in zero crossing of voltage.For relay outputs the time between two connections ordisconnections is set to two seconds. Transistor outputshave no limitation of the switching period.

Net returnAfter net return, the set discharge time runs for therelay outputs. The transistor outputs do not mention thedischarge time.

Hints for installationMounting placeThe reactive power controller Prophi is suited formounting and operation in reactive power compensati-on systems.

The connection is carried out on the back side via touchproof spring power terminals.

Measurement and auxiliary voltageThe measurement is suited for 3 phase systems with orwithout neutral conductor. Measurement and auxiliaryvoltage are taken from the measurement voltage andmust be connected to the building installation via aseparation (switch or power switch) and an overcurrentprotection (2A.. . 10A).

A t t e n t i o n !The operating voltage for the contactorsshould be taken from an outer conductorconnected to the reactive power controller.

Diagr.: Connection of measurement and supply voltageand current transformer.

!

The reactive power controller measures and supervisesthe voltage between two outer conductors. If one ofthose two fails, the reactive power controller gets nomore measurement and operating voltage, and switcheson the capacitive stages after net return according tothe programmed times.If the third outer conductor is missing, this will not berecognized by the reactive power controller. If thecontactors are supplied by this outer conductor, thecontactors can attract simultaneously and withoutconsideration of the discharge time after net return.

Current measurementThe current transformer is connected to the clamps kand l (/5A or /1A) from the outer conductor L1.Please ensure during the installation of the currenttransformer, that the current transformer is passed bythe consumer current but not by the compensationcurrent .The current can be measured by an Amperemeter tocompare it with the current indicated by Prophi to check.Please note, that the factory's presettings of the currenttransformer ratio is set to 10 and must be adapted to theexisting current transformer.If you should short-circuit the current transformer, theindicated value on Prophi must decrease to 0A.

Examples for the setting of the current transformerExample 1Current transformer 2 0 0 A / 5 ASet Prophi to 4 0

Example 2Current transformer 5 0 0 A / 1 ASet Prophi to 5 0 0

Example 3Sum current transformer 1 0 0 0 A + 1 0 0 0 A / 1 ASet Prophi to 2 0 0 0

A t t e n t i o n !For unequal load of the outer conductors, thecurrent should be measured in the outerconductor, which is loaded most heavily.

Real powerIf current and voltage are connected to Prophi accordingto the connection diagram, a positive real power isdisplayed in case of real power consumption. Real powerwith a negative sign in the indication points to the supplyof real power or an error of connection.Possible error:- Voltage and current are measured in the wrong outerc o n d u c t o r .- The current transformer clamps (k-l) are exchanged.

Learning of the configurationAfter installation of thecontroller there is thepossibility to learn andsave the configurationwith the function" l e a r n " .

Important requirements are:- The discharge time for capacitors is set to 60 seconds,when the device is delivered. For capacitors with longerdischarge times, the discharge time must be checkedand changed before using the "learn" function .- The current transformer must be flown through byconsumer and compensation current.- The measurement and supply voltage may not be takenfrom phase to N.- The compensation system must be ready for operation.

The learning function of the controller is devided intotwo steps:Step 1 - Learning of the connection configurationHere the correction angle between current transformerand measurement and supply voltage is detected.Step 2 - Learning of the capacitor stagesHere the number of outputs and the stage power ofeach stage is detected.The following requirements are neccessary:- The switching of a capacitor stage must cause a changeof current of at least 50mA at current input.- The stage power of the stage to be learned must bebigger than 1% of the measuring range of the controller.

A t t e n t i o n !After learning, the saved configurations must bechecked, if they are plausible.

The following actions can be carried out:o F F - No learning. 1 - Step 1, learning of the connection configuration. 2 - Step 2, learning of capacitor stages. 3 - Step 1 + 2, learning of the connection

configuration and capacitor stages.

Case b.The generated real power is bigger than the demand.Real power is supplied.

Case c.The generated real power corresponds to the demand.

In all cases the required reactive power is supplied by theenergy supplier, or even better, by a compensation system.The following situation can come into being. The neededreal power is completely generated (case c.) by thegenerator, and the reactive power is completely suppliedby a compensation system.There is no current flowing through the currenttransformer. If the power station service, by mistake, ison "oFF", the capacitor stages are disconnected. Then areactive current is flowing again through the currenttransformer. The controller detects a need for compensa-tion, and connectes the stages again. The reactive currentis compensated. Again, no current is flowing.The problem is, that the number of switchings is increased.For power station service, especially in case c, the powerstation service should be set to "on".

Fan controlWith the temperaturefeeler, inserted in Pro-phi, and a fan, a simplefan control can be es-tab l i shed .Therefore, an

upper temperature limit, alower temperature limit and aswitching output

must be fixed.Please note, that the inner temperature of the Prophi isabout 2°C over the outer temperature.A relay output or the alarm output (option) serves as fano u t p u t .If the switching output 0 is assigned to the fan control,the fan control is not active.An upper and lower temperature limit can be set. Thetemperature limits can be set in the range of 0°C and98°C in 1° steps. While programming, you can only setan upper limit, when it is at least 1°C over the lowerl i m i t .

Attention ! If an output is programmed for fan control,and if it is also programmed for a fix stage or alarmoutput, the fan control has priority.

Overtemperature disconnectionIn cabinets there might be an exceeding of the innercabinet temperature, effected by power dissipation ofconnected capacitor stages or too high outer temperature.In that case, also the Prophi controller is heated up, andthe inner temperature feeler detects this rise of temperaturewith a little delay. With the overtemperature disconnec-tion, connected stages can be disconnected in order todecrease the inner temperature and to protect thecapacitors from damage.The following values can be set:

- upper temperature limit,- lower temperature limit and- pause time.

Attention! The overtemperature disconnection alsodisconnects programmed fix stages.

Upper temperature limitIf the upper temperature limit is exceeded, connectedcapacitors are disconnected.

Lower temperature limitIf the lower temperature limit is exceeded, no morestages are connected anymore.

Pause timeIf the lower temperature limit is exceeded, one capacitorstage will be disconnected, and the pause time is started.After the pause time is over, the next capacitor stage canbe disconnected.
