摘要
Abstract
To prevent stability risks in the AC power grid caused by the fault restart of ultra high voltage direct current(UHVDC)lines,the restart of one pole needs to block the restart logic of the other pole.However,the transmission of blocking commands between the two DC control systems exsits communication delay.When the fault interval time between the two poles is less than the inter-pole communication delay,it will lead to the blocking of both poles.By optimizing the restart logic and introducing the maximum inter-pole communication delay parameter,the DC control systems can choose to restart one pole when the actual inter-pole communication delay is less than the maximum inter-pole communication delay.The real time digital simulation(RTDS)test and field application verify the feasibility of the optimized logic.By reasonably setting the maximum inter-pole communication delay,the problem of bipolar blocking caused by short-term successive faults in the two-pole lines in actual projects can be effectively solved.关键词
