摘要
为满足新建某500kV线路输电工程系统现场启动调试需要,利用PSCAD分析软件对即将投产得该工程进行工频过电压、操作过电压、潜供电流与恢复电压的计算分析。结算结果均满足相关规程规定要求,并为保证该工程系统现场启动调试过程中设备安全和确定过电压保护配置及重合闸时间提供理论依据,为运行提供参考。该工程内过电压计算也为同类工程的过电压计算提供参考。
In order to meet the need of start debugging with a new 500kV line of site power transmission engineering system, uses PSCAD analysis software to analyze and calculate the power frequency overvoltage, switching overvoltage, secondary arc current and recovery voltage forl soon put into production of the project. The results are related to the settlement procedures to meet the requirements, and to ensure that the system works in the field to start the debugging process to determine the safety and overvoltage protection configuration and reclosing time to provide a theoretical basis, provide a reference for operation. Overvoltage calculation of similar projects within the project also provides overvoltage reference for the calculation.
