摘要
提出了一种基于 dq0变换和专家系统的电能质量信号辨识新方法。利用 dq0变换后的 d、q和 0序分量 ,能对单相、两相或三相电压出现电能质量问题的电力系统电压进行准确有效的信号特征提取 ;利用这些信号特征 ,结合相应的基于规则的专家系统能有效地进行电能质量信号辨识。
In this paper,a new approach based on dq0 conversion method and expert system is proposed to classify power quality signals.In this method, the features of the three-phase power system voltages can be extracted by the dq0 conversion method ,and these features are used to identify the power quality signal effectively th rough an expert system based on rules.The validity of the proposed method is ver ified by the results of the simulation calculation.
