摘要
静止同步串联补偿器(SSSC)具有快速调节线路潮流的功能,对含SSSC电力系统的数学建模是深入研究SSSC的第一步。在两相同步旋转d-q坐标系下建立了装有SSSC双机系统的静态潮流方程并应用输入变换实现了有功和无功的解耦,同时给出了变换后等效的系统矩阵及所采用的输入变换矩阵。在MATLAB中对含有SSSC的双机电力系统进行了仿真,结果验证了该解耦策略的有效性。
Fast power flow control is one of the main tunctions of SSSC (static synchronows series compensator), and the mathematical modeling of the power system with SSSC is the first step to study SSSC. The static power flow equations for two generator power systems with SSSC are built in a synchronously rotating d - q frame by using Park's transformation. The input transformation technique is applied to decouple the active and reactive power flow. The equivalent system matrix and the input transformation matrix are given. The efficiency of the proposed decoupling technique is estimated in the MATLAB platform. Simulation results prove the availability of the decoupling technique.
