摘要
分析了发电机励磁控制系统的结构、控制原理;以200MW水轮发电机为例,对以PID控制方式的励磁控制系统进行了研究.在此基础上,基于MATLAB/Simulink软件,建立了同步发电机及其励磁调节系统仿真模型.并在Simulink环境下进行了系统发生三相短路故障的仿真.从仿真结果分析,系统发生短路故障时对发电机的稳定运行有很大的影响;参数合理的励磁调节器能使发电机在故障切除后较快的恢复稳定运行状态.
Take the example of 200MVA hydro-generator, the matnemaUcai mooei oi me excltanon control system of huge hydro-generator is analyzed and the automatic voltage regulator （AVR） using PID control mode as the main research content of the excitation control system is researched. The simulation model is constructed in Matlab/Simulink environment. The results show that adjusting generator excitation system contributes to the stable operation of hydro-generator and power system generator restore stable faster. Reasonable parameters of excitation regulator make the
