ABSTRACT
A method of control and detailed hardware designation of the thyristor switch capacitor (TSC) controller is presented in this paper. After measuring the voltage and the current of network and work out the power of it, comparing to the voltage on the capacitors, the controller may group the capacitors and choose optimal mode to switch the capacitors into the network, which can compensate the reactive power of the network, according to varying load. The phase compensation designation in the measuring circuit can eliminate the warp in the electrocircuit and the compensation of the reactive power can be realized quickly by the hardware circuit of the control system, without reactive power reversing and switching oscillating.
KEY WORDS: reactive power compensation, TSC controller, switching the capacitor, phase compensation
