摘要
针对蒙西电网外送电力的南北双通道潮流不均问题,提出了在北通道上加装移相器、加装移相器和串补以及仅加装串补等措施。在进行了各方案的潮流分析后,提出了在汗海—沽源、沽源—平安城线路分别加装40%和45%串补的设想,同时建议加设汗海—沽源—平安城第三回线路,以提高蒙西电网的外送能力。
This paper presents several measures to uneven power flow between the north and south outer corridor on western Mongolia grid, such as adding phase-shifting transformer, phase-shifting transformer plus SC,and only SC as well. After compared power flow results,the suggestion of adding 40% SC on Hanhai-Guyuan lines and 45% SC on Guyuan-Pingancheng lines and adding the 3 rd line on north corridor are proposed ,which will improve outer transmission capacity of western Mongolia grid.
