PURPOSE:To control highly accurately a reactive power compensator by executing the operation of primary delay processing and reset filter processing by an operating means based upon software. CONSTITUTION:The voltage of a power system 1 is detected by a voltage detecting circuit 5 and a signal obtained through a delay circuit 7 having a delay element of which time constant is variable and a signal outputted from the detecting circuit 5 are inputted to a voltage control circuit 9. A thyristor ignition phase control circuit 11 determines the control variable of a thyristor device 3 in accordance with the output of the circuit 9. A current detecting circuit 13 detects the current of the device 3 and determines the time constant of the delay circuit 7. The operation for the primary delay processing of the delay circuit 7 is executed by the operating means based upon the software. |
