摘要
利用RTDS将仿真试验结果和实际故障录波数据、波形进行对比研究,成功地再现了#2主变跳闸时的故障过程。通过仿真环境下测试PST1200型主变保护装置差动速断在TA饱和时动作情况,找出了此次#2主变跳闸事故的真正原因。
The comparisons have been carried out between the simulation results and the fault data using RTDS simulation. The accident of No.2 main transtbrmer is simulated successftdly. In the simulation, PST1200 transformer protection device diflkrential over current protection is tested when TA saturation. The causes of the fault of #2 main transformer tripping accident have been found out.
