摘要
研究了在系统不对称情况下基于多重化结构的静止同步补偿器 (STATCOM )的分相不对称控制 ,详细分析了δ θ分相控制算法及其控制效果 ,并在此基础上提出了δ控制方法。通过对 2种控制算法在谐波产生、最大负序补偿度等方面的分析表明 ,δ分相控制的总体控制效果优于δ θ控制。仿真结果验证了理论分析的正确性。
Unbalanced control for Static synchronous compensator (STATCOM) based on multiple inverter configuration under asymmetric power system is studied in this paper .The algorithm and the control effect of δ θ(delta theta) unbalanced control strategy are analyzed in detail. On the basis of analysis results, δ(delta) unbalanced control method is proposed. Comparing the harmonic generated and the unbalanced degree compensated by using both δ θ and δ control strategies, it is showed that the control result of δ method is superior to that of δ θ control method.The theoretical analyzing results have been proved by computer simulation.
