| Abstract: | Aimed at the over compensation or de-compensation problems existing in the agricultural power networks, a new method for harmonics and reactive power check is proposed on the basis of wavelet transform and integration with instantaneous reactive power theory. Through MATLAB simulation, the method can check the high order harmonics and reactive current in the agricultural network, thus can guarantee the safe, reliable and economical operation of the agricultural power network. |

| Keywords: | agricultural network instantaneous reactive wavelet harmonics reactive compensation |
