摘要
就农网中存在的无功过补和欠补问题,在小波变换的基础上,结合瞬时无功功率理论,提出了一种新的谐波和无功检测方法。通过计算机MATLAB仿真,该方法能很好地检测农村电网中的高次谐波及无功电流,为农网安全、可靠和经济运行提供了保障。
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.
