摘　　要：建立了高压静止无功补偿器(SVC)的矢量模型,并对其电流、电压进行矢量分析,在此基础上推导出基于矢量分析的补偿导纳计算方法,并用Psim软件进行了控制模型的仿真。叙述了SVC光电触发及监测系统的软硬件设计原理,依照所述方案构建高压SVC样机并进行开环及闭环实验。仿真和实验结果表明,该系统工作稳定,调节性能良好。The vector model of high voltage static var compensation（SVC） is established,the vectors of its voltage and current are analysed,according to whitch a new type of calculating method of compensated admittance based on vec-tor analysis is derived.The control model of the new method is simulated by Psim.And then the design principle of hard and soft for photoelectric firing and monitering system is presented.A high voltage SVC prototype is developed and tested in open and closed loop.The simulation and experimental results prove the stable operation and excellent regulation performance of the presented scheme.
