Coordination of Blackout Prevention and Control Methods for UHV AC/DC Power System
Combined with the UHV AC/DC power system under construction in China.,this paper systematically establishes the the blackout cooperative prevention and control system for UHV AC/DC power system,in order to further ensure the safety of power system operation and enhance the ability to prevent blackout.The system is composed of several parts:the cooperation of prevention methods corresponding to system faults in different periods,different fault types and cooperation methods between AC and DC systems,turbulence prevention from affecting each other system and DC system assistance to AC system if necessary.For each part,it introduces the international technical status,the reasons and benefits to utilize cooperation in blackout prevention,as well as the actual solutions in methods cooperation for blackout prevention.The research results has some reference value in helping formulate blackout prevention plans and fully enhancing blackout preventing ability for UHV power system.
