三相交流电路中瞬时功率的分析和研究

Analysis and Study on Instantaneous Power of Three-phase AC Circuit

基于瞬时无功功率理论分析了α-β坐标中的功率成分和三相电路中各相功率间的关系.为检测谐波电流和无功电流提供了研究的方法.

Based on the theory of instantaneous reactive power, the paper tries to show the relations between the power ingredients of coordinates and various power of threephase AC circuit, it provides a study base for detecting harmonious current and reactive current.
