摘要
国家脉冲强磁场科学中心(筹)从美国引进的100 MW脉冲发电机电源系统的绕线式异步电动机的额定频率为60 Hz,同步转速为720 r/min,但当其供电频率为50 Hz时,其额定转速达不到其设计值,导致与电动机转子同轴的发电机飞轮的储能也达不到设计值185 MJ。针对该问题,设计了一套双闭环解耦控制的双馈调速方案,使得该电动机能够稳定运行于转速为720 r/min的超同步工况。用MATLAB/Simulink传真平台建立100MW脉冲电源系统电动机的超同步双馈调速系统的模型,并结合相关实际参数,针对超同步运行状况进行仿真。仿真结果证明了该双馈调速系统设置的正确性。
100 MW pulsed power supply system introduced from America by Wuhan National High Magnetic Field Center （WHMFC）induces can be used for various energy storage tests for that designed woking rated frequency of asynchronistic motor of this system is 60 Hz and its synchronized speed is 720 r/min, but while its power supply frequency is 50 Hz, the ra- ted rotating speed can not reach to designed value and the energy storage of coaxial generator flywheel with the motor rota- tor can not reach to designed rated value which is 185 MJ. Aiming at this problem , this paper designs a set of doulbe-loop decounpling controlled doubly-fed timing scheme which is to stablize the operation rotating speed under an super synchro- nized working condition at 720 r/min for the motor. It uses MATLAB for establishing an super synchronized doubly-fed tim- ing system model of 100 MW pulsed power supply system and combines related practical parameters to carry out simulating aiming at super synchronized operation conditions. The result proves correction of settings of the doubly-fed timing system
