Power factor controller FCR12

In unbalanced systems it is necessary to measure current in each phase and calculate needed compensation power from real three-phase powers. FCR06T and FCR12T controllers are available with three current inputs.

4 quadrant measurement and regulation
three regulation methods (APFR default)
ready for classic, dynamic and hybrid PFC
monitoring of U, I, P, Q, S, cosφ, THDU, THDI,
monitoring of odd harm. of U and I till 19^th order
thyristor control speed up to 25 operations in 1 s
6 or 12 regulated outputs
ready for de-compensation PFC

Function

Device digitizes measured phase voltage and current in one phase. Then, from those values, parameters like: power factor, effective values of voltage and current, apparent power and reactive power, are calculated. With consideration of requested cosφ it calculated need compensation power. According to its size, regulator switches on or off appropriate capacitor stages.

Within the scope of each power level, regulator uses method of circle switching. All the time connects this stage at appropriate power level which was switched off for longest time. Everything is made so that regulator will reach optimal compensation in one regulation cycle with minimum number of switched stages.

Alarms

Power factor controllers FCR06 and FCR12 have several alarms which are adjustable by level, min time of event, action on regulated steps etc. Special alarm from temperature is able to control forced ventilation of PFC and protect capacitor steps against higher temperature.

De-compensation

The controllers FCR06 and FCR12 have features for smart de-compensation with several reactor steps operating in a similar way as capacitor steps or only one reactor that is tuned by capacitor steps.

Cascade operation of two controllers

Two controllers in variant C can be connected together to expand the number of controlled steps or substitute for each other in a system with two main power supplies. Any one of controllers can behave as a master or slave.

Software

Thanks for software Power Monitor System is possible controllers with RS485 easily configured and also use for monitoring of PFC systems.
