| Abstract: | Several common methods of detecting harmonics and reactive current for power systems are introduced. Based on the theory of reactive power, it argues that harmonic detecting methods can accelerate the speed of dynamic response of harmonic . Based on FFT detecting method, detecting harmonics and conducting spectral analysis can be realized. |
