【摘要】 在应用小波变换信号奇异性检测理论进行故障检测基本判据的基础上,对其进行了补充,提出了电力系统故障检测的补充判据,提高了故障检测的准确性,同时使故障检测判据更具可操作性。并给出了10 kV系统单相接地故障的MATLAB仿真实例。更多还原

【Abstract】 On the basis of applying wavelet transformation singularity detection theory to fault detection,a complementary criterion to power system fault detection criterion was made,with complementary groundnesses for the system fault detection,which can make fault detection more accurate and ease of operation.And an example of one phase grounded,based on MATLAB has been introduced in 10 kV system.更多还原
