摘　　要：文中采用扰动功率法对电压骤升、电压骤降、短时停电等短期电能质量扰动进行扰动源的判定,对公共连接点的各个支路,其扰动功率初始峰值极性作为扰动方向判定的依据,极性不同的支路为扰动源所在的支路。仿真结果表明,该方法对判定电压骤升、电压骤降、短时停电等短期电能质量扰动的扰动源有较好的效果。The determination of short-term power quality disturbance source is put forward by disturbance power method in this paper.Polarity of the initial peak of disturbance power is the basis for determining disturbance direction.Disturbance source is located in the branch where polarity is different.The result of simulation indicates that it is useful to recognize disturbance source of voltage swell,voltage sag and voltage interruption with this method.

关 键 词：短期扰动 扰动功率 扰动源
