摘要
介绍了站用交流系统的组成,在PSIM软件中搭建了以ATS装置为核心的站用交流系统,通过各电气量的波形特征,分析了低压带电压差合环和开关级差失配造成的危害,并针对这两种异常提出了相应的防范措施,以确保变电站运行的可靠性。
The composition of AC system for substations is introduced.The AC system for substations with the ATS device as the core is set up in PSIM software.Through the waveform characteristics of electrical parameters,the harm caused by low-voltage loop closing with voltage difference and mismatch of switch level difference is analyzed,the corresponding preventive measures are proposed for these two abnormal cases to ensure the reliability of substation operation.
