当今电能质量的新含义及分析

New Definition of Power Quality and Its Estimation at the Present Time

介绍了电能质量的概念,包括频率偏移,电压偏移,电磁暂态,波形失真,三相不平衡以及电压波动和闪变等.分析了影响电能质量的各种因素,讨论了电能质量不满足要求时可能造成的危害.

This paper discusses the concepts of power quality, such as power frequency variations, voltage variations, transients, waveform distortion, voltage imbalance,voltage fluctuations and flicker. The effects of power quality on electric equipment and the factors influencing power quality are also described.
