Abstract
In order to solve the DC side capacitor voltage unbalancing problem of cascaded static synchronous compensator( STACOM) ,by comparing and analyzing three usual methods,it studies a kind of control strategy about three-phase voltage,this combines interphase control and phase control and based on real time tracking characteristics of external loop voltage. Because the inter phase control can regulate inter phase voltage balance without influencing system's stability of outer voltage,this can achieve each link capacitor voltage balancing control by changing the size of the active power that the chain unit absorbing. PSCAD is used to simulate and verify this method. Finally,the simu-lation results are verified by building the experimental platform.关键词
