摘要：
When large-scale wind power is transmitted with HVDC system, the sending voltage will swell under HVDC blocking contingencies and the wind farms will be confronted with severe high voltage ride through (HVRT) problem. To ensure the wind farm operating in security, power assignation principle and controllability for grid-side converter (GSC) of doubly fed induction generator (DFIG) considering its constraints was discussed. Then the sequence of events such as coordinating control modules, putting into static var compensators (SVC) and cutting off the sending AC filters was coordinated on the basis of different response times. An effective HVRT coordinated control strategy was put forward. Simulated results indicated that the scheme could ensure the generators not running off grid during faults and accelerate fault network recovery by providing reactive power support to it. © 2018, Power System Technology Press.
