针对STATCOM的原理结构特点,依据瞬时无功功率理论分析了其无功电流检测原理以及电压的控制策略,它将三相对称的交流量变为两相直流量分别进行控制,实现直流侧电压均衡控制,达到了无功补偿的目的。10kV配电网负荷的变化幅度大,电压质量问题严重,将STATCOM无功补偿技术应用到10kv配电网中,补偿效果明显,并指出了静止同步补偿器技术在未来城市配电网的发展趋势。
According to the principle structure characteristics of STATCOM, the reactive current detection principle and voltage control strategy are analyzed according to the theory of instantaneous reactive power. The three-phase symmetrical alternating current is changed into two-phase direct current to control the DC voltage balance control , Reached the purpose of reactive power compensation. The variation of load of 10kV distribution network is large and the voltage quality is serious. By applying STATCOM reactive power compensation technology to 10kV distribution network, the compensation effect is obvious, and the development trend of static synchronous compensator technology in future urban distribution network is pointed out .
