摘　　要：为验证湄洲湾电厂培训仿真系统能否满足电厂培训要求,以引风机跳闸和给水泵跳闸为例,进行了故障工况下的快速减负荷(RB)仿真试验,分析了仿真机组关键参数的变化趋势,并与实际机组现场数据进行了对比分析。试验表明,该仿真机组主要参数动态特性与实际机组非常吻合,动态精度较高。表明该仿真系统动态精度完全满足电厂仿真培训要求,可以用于电厂运行分析。A simulation system was developed for Meizhouwan Power Plant was built to train the operators. In order to validate the precision of the simulator, and verify the simulator can meet simulated training requirement or not, dynamic simulated tests on RUNBACK （RB） operation status of ID Fan trip and feedwater pump trip are carried out, the effects of RB on some main operation parameters are analyzed and the results of simulated tests are compared with the data of the actual unit. It shows that the dynamic feature of the simulated unit is same to the actual unit; the dynamic precision of the simulator is relatively high. It indicates that the dynamic precision of the simulator can meet simulated training requirement and the simulation system can be used on running analysis of the power plant.
