摘　　要：电力系统电能质量的动态电能质量问题包括:电压跌落(电压骤降)、电压骤升、谐波、间谐波、电压波动、频率偏差、三相电压不平稳等。其补偿可通过改善负荷特性,降低用户用电设备对电能质量的敏感程度或者加装补偿装置,抵消系统干扰两种方法完成。The dynamic electric energy quality problems of electric energy quality in power system includes voltage drop （voltage descending）, voltage ascending, harmonic wave, indirect harmonic wave, voltage fluctuation, frequency deviation, unstable three-phase voltage and so on. Its quality compensation can be realized by improving load features, reducing the sensitivity degree of user electric equipments to electric energy quality or adding compensation equipment, and counteracting system disturbance.
