摘要：

针对电网运行电压不稳定的情况,采用静止同步补偿器(STATCOM)对电网进行无功功率补偿以稳定运行电压。文中给出了运行电压和无功功率的关系,阐述了STATCOM的基本结构与工作原理,分析了STATCOM的控制方法及策略。并根据工作原理和控制方法,在Matlab环境下搭建了基于δ和λ的双控制变量STATCOM模型。仿真结果表明,STATCOM可精确、快速地补偿电网所需无功功率,达到了稳定运行电压的目的。

Abstract:

Aiming at the unstable condition of running voltage of power grid,Static Compensator (STATCOM) is used to compensate reactive power for power grid to stabilize running voltage.The relationship between running voltage and reactive power is given.The basic structure and working principle of STATCOM are discussed.The control method and control strategy are also described and analyzed.According to the working principle and control method,STATCOM model based on the two controlling variables of δ and λ is built in the Matlab environment.Simulation result shows that STATCOM can precisely and quickly compensate reactive power which the power grid desires,and the purpose of stabilizing running voltage is achieved.

Key words: stabilize running voltage;reactive power compensation;STATCOM;STATCOM model simulation;voltage flicker mitigation
