Three-phase user load control method based on current detection

The invention provides a three-phase user load control method based on current detection. The three-phase user load control method comprises the following steps: step (1), collecting a user power utilization residual current signal and a current signal of each phase; step (2), performing preliminary control on electricity utilization of a user according to the current signals of each phase; (3) the residual current signals at the t1 moment and the t2 moment are called; (4) judging whether the three-phase user has a fault or not according to the residual current signals at the moments t1 and t2; and (5) determining a fault phase, and performing reliable control processing. The invention provides a three-phase user load control method based on current detection, and the method can accurately judge whether a three-phase user has a fault or not, and carries out the timely and effective control. 本发明提供了一种基于电流检测的三相用户负荷控制方法，所述三相用户负荷控制方法包括以下步骤：步骤(1)：采集用户用电剩余电流信号、各相电流信号；步骤(2)：根据各相所述电流信号对用户用电进行初步控制；步骤(3)：调取t1、t2时刻所述剩余电流
