摘要
提出并建立了一种基于能量缓冲的新型统一潮流控制器 (UPFC)模型 ,使得UPFC除了具有能够即时控制并联无功补偿、串联阻抗、有功调整能力 ,同时具备有功吞吐的能力 ,因此对缓冲系统振荡和事故冲击具备更高效的阻尼调节。文中给出了基于状态变量与d q分解的系统控制策略 。
A novel model of Unified Power Flow Controller (UPFC) with energy snubber is presented and accomplished. It makes UPFC not only can control the compensation of shunt converter's inactive power, series impedance and regulation of active power, but also has the capability of absorbing or giving off active power. Therefore, the UPFC with snubber can improve system's damp and support the contingencies' impulsion. The control strategy based on state variable and d q axis decoupled is implemented. With the mathematic simulation software “Matlab', the model is tested and proved successfully.
