电气化铁路接入风电汇集地区电网的负序优化补偿策略研究
随着我国西部地区风电场规模的不断增大且电源接入点稀少,导致牵引所和风电场的耦合度较高,电铁面临的负序问题更加严重.因此,计及双馈风电场的主动补偿能力,提出了一种电气化铁路接入风电汇集地区电网的负序优化补偿策略.首先,建立了电气化铁路牵引变电所和双馈风电场的负序阻抗模型,牵引变电所包括 V/v接线牵引供电系统和静止无功发生器(static var generator,SVG).其次,分析了V/v接线牵引供电系统的负序特性,推导了计及风电场主动补偿能力的负序传播模型.然后,给出了双馈风机(doubly-fed induction generator,DFIG)的剩余容量计算方法,提出了协同控制SV...
