摘要
不平衡系统中的静止同步补偿器(STATCOM)控制是该领域的重要研究内容。在平衡系统和含负序分量不平衡系统中对STATCOM的输出特性进行了仿真对照分析,结果表明当交流电源系统中伴随负序分量时,会出现非受控的两倍频有功潮流,导致直流电压的电容电压快速变化,产生难以消除振荡。在此基础上推导出了含负序分量不平衡系统中STATCOM潮流计算关系,为解决STATCOM输出振荡问题提供了理论依据。
The simulation of STATCOM output characteristics under balance system and the negative sequence component unbalanced system was compared When the AC power system was accompanied with negative sequence component, twice frequency uncontrolled power flow appeared, which led to the rapid change of DC voltage capacitor voltage, and produced oscillation that difficult to eliminate. Considering this, power flow calculation relations of STATCOM under system containing unbalanced negative sequence component was deduced, so that a theoretical basis for solving the output oscillation problem of STATCOM can be provided.
