Abstract
During plant power supply switching, the voltage on bus goes through decaying to recovering, while impulse current occurs in line during this process, which affects the switching of plant power supply. Based on the characteristic of the voltage on bus and inrush current, induction motors is divided into grouping by considering dynamic stability of induction motor. Then, each group is taken as one equivalent induction motor, both of which have same power loss. In the end, the simulation is carried out in EMTDC. The results show that equivalent simplified model is suitable for three kinds of modes of plant power supply switching.关键词
