SVC平衡控制方法及其所需信号的检测

本文探讨了静止无功补偿器（SVC）在三相对称和不对称、电压电流波形有畸变情况下的平衡控制方法和控制信号检测的方法。对于控制所需要的信号，包括电压和无功电流的有效值、无功功率和功率因数等，给出了基于瞬时功率理论的信号检测方法。对所提出的方法进行仿真并将该方法应用于近期研制的SVC样机的设计，结果表明，它们是快速有效和准确的，具有实际的工程应用价值。

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.
