摘要
使用短时傅立叶变换方法处理电网暂态谐波的测量数据,并对测量系统进行了仿真测试.仿真测试结果表明,各谐波幅度的测量值与理论值相差小于5‰.
The data of measurement of power network transient harmonics are processed by using the short-time fourier transformation, and the measurement is simulated. The results of simulation has shown that the relative errors of measurement are 5‰ less than theoretic value.
