A balance control method and signal detection needed for SVC control

A balance control method and signal detection needed for static var compensator (SVC) control under the conditions of symmetrical and unsymmetrical voltages or currents with or without distortions are described in this paper. Based on the instantaneous power concept the detection method for the required signals such as the root\|mean\|square value of the voltage and the reactive current, the reactive power and the power factor is developed in detail. The simulations and the practical application in the design of a SVC model have shown that the proposed method is very effective, accurate, and with fast response performance.
