摘要
本文针对三电平STATCOM在三相电网电压不平衡情况下,为了能够准确快速检测出负载电流的基波无功、负序以及谐波分量,提出了一种基于微分环节的改进指令电流检测方法,并对该检测方法在电网电压不平衡条件下的检测效果进行了仿真分析。
In this paper,under unbalanced voltage of Three-level STATCOM,an improved method based on differentiator is presented to detect the fundamental reactive component, the negative and harmonic components of load current quickly and accurately in the case of grid voltage unbalance.Performance of the proposed detection method under unbalanced voltage is evaluted based on simulation analysis.
