摘　　要：提出计及电动机负荷模型的配电系统状态估计方法。该方法在ZIP静态负荷模型的基础上,进一步结合电动机模型,通过增加电动机负荷模型内电势节点,构造负荷节点和电动机节点的零注入量测方程,并利用加权最小二乘法来求解。对IEEE33节点配电系统的仿真显示,该方法能够提高状态估计准确度。In this paper,a state estimation method of power distribution system considering the motor load model is proposed.Based on the ZIP static load model,the motor model is further combined.By adding potential nodes in the motor load model,the zero-injection measurement equation of the load node and the motor node is constructed,and the weighted least squares method is used to solve it.The simulation of IEEE33 node power distribution system shows that this method can improve the accuracy of state estimation.
