摘　　要：准确快速地检测电网中电流的谐波成分,是保证滤波器具备良好工作性能的关键。介绍一种基于瞬时无功功率理论的谐波电流检测及其仿真验证的方法。仿真结果表明,该方法能够实时准确地跟踪电网谐波电流变化,消除电网电流中大部分的高次谐波,精确度与准确度均可满足系统要求。The key to guaranteeing the work performance of filter is the real and fast time detection of harmonic ingredient of current in power system. The method of reactive current detection and simulation verification based on instantaneous reactive power theory was introduced in this paper. The result shows that this method satisfies the systemic demands.
