电气化铁路电能质量综合治理控制策略研究

Control Strategy Research on Electrified Railway Power Quality's Comprehensive Treatment

链式静止同步补偿器(STATCOM)是解决现有的电气化铁路电能质量问题的有效手段。针对链式STATCOM提出了一种多PR调节器并联的多目标控制策略,可以自动补偿无功电流及部分低次谐波电流,同时,也可对链节悬浮电容电压的平衡进行有效控制,达到电气化铁路电能质量综合治理的目的。最后,通过链式STATCOM实验样机,验证了多目标控制策略的可行性及有效性。

Chain static synchronous compensator(STATCOM)is effective to solve the existing problem ofelectrified railway power quality. Put forward a more PR regulator parallel multi-objective control strategy forSTATCOM. That could automatically compensate the reactive current and part of low harmonic current. At the sametime,it was also effective to control link suspended capacitor voltage to achieve the goal of electrified railway powerquality comprehensive treatment. Finally,the result of the chain STATCOM experiment prototype verifies thefeasibility and effectiveness of the multi-objective control strategy.
