摘要
利用小波变换提取故障时的暂态电量信息,构造出了基于小波变换模极大值奇异性检测原理的新型选线判据,并通过典型的10 kV仿真算例,验证了该方法的可行性,仿真结果表明利用小波分析理论对电力系统故障暂态信号特征提取处理是行之有效的方法。
Wavelet transform is used as a tool to pick up electric energy information in transient stability, new type of line selection is proposed based on wavelet transform maximum unique testing principle. In the light of typical 10 kV simulation calculation, the feasibility of method is tested. It is effective to use wavelet transform analysis to pick up electric energy information in transient stability.
