Research on Cross-Section Overload Control Time of 500 kV Main Transformer afterN-1 Fault
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 pre-plan 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 cut-off under 500 kV failure is realized
it provides a reference for realizing fast control cross-section limit crossing when 500 kV main transformer fails.
