Abstract
The dynamical response of three-order induction motor based load model is analyzed when its stator windings is grounded. As a result, this paper proposes that during disturbance the reactive power releasing of induction motor located in sending-end would sustain system voltage. It benefits system stability. Measured integration load model (induction motor + ZIP) and static load model (ZIP) of Zhangjiakou district are used to calculate critical clearing time of Shaling-Changping 500 kV line. And the Comparison of results verifies the theoretical analysis. This paper emphasizes the validity of measured dynamic load model and presents a new idea, which is to study power system transient stability from the point of reactive power view.
