摘　　要：针对设备N-1故障后断面功率越限、电网供电能力下降等问题,分析目前断面越限控制时间的特点及原因,提出预案可视化的方法。将500 kV主变压器故障下的事故预案在系统中图形化以及批量控制一键化操作,实现500 kV故障情况下快速转移或者切除负荷,为500 kV主变压器发生故障时实现快速控制断面越限提供参考.In order to solve the problems of cross-section power exceeding limit and power supply capacity decreasing after N-1 fault,the characteristics and reasons of cross-section exceeding control time are analyzed,and the visualization method of preplan is put forward.By making the accident preplan of 500 kV main transformer failure in the graphical and batch control one cliok operation of the system,fast load transfer or cutoff under 500 kV failure is realized,it provides a reference for realizing fast control cross-section limit crossing when 500 kV main transformer fails.
