ABSTRACT:With the 10.5 kV/8 000 kW synchronous motor of Donglei Pump Station as a practical research case and in accordance with the requirements of the starting of the synchro-nous motor,this paper analyzes and calculates the bus voltage drop at all levels of the power supply system which uses full-voltage starting method. Besides, this paper gives dynamic simulation results of the full-voltage starting process of the synchronous motor with ETAP and analyzes the influence of the bus voltage drop on the unit operation stability and the useful measures that can be used to reduce the impact of starting pre-ssure drop. Therefore the paper has certain reference significa-nce to the actual engineering.
