摘要 为解决西北新能源大规模外送系统的无功电压控制问题,提高电网的安全稳定性,在新疆与西北主网联网750 kV第二通道上规划装设多套可控电抗器和静止无功补偿器等大容量新型FACTS设备。为此提出了FACTS设备的技术应用方案,并对FACTS设备的稳态调压效果进行详细分析。同时从提升联网通道输电能力和提升故障后电压恢复水平2个方面研究了FACTS设备对系统暂态稳定性的提升作用。最后,从抑制系统过电压和潜供电流的角度,分析了FACTS设备对电磁暂态问题的影响。 In allusion to the control of reactive power and voltage during the large-scale transmission of power generated by new energy source base in Northwest China and to enhance the security and stability of power grid,it is planned to install multi sets of new types of high-capacity FACTS devices such as controlled shunt reactors(CSR) and static var compensators(SVC) in the second 750 kV transmission line to connect Xinjiang power grid with Northwest power grid.A technological scheme for the application of these FACTS devices is proposed and the steady-state voltage regulation effect of FACTS devices is analyzed in detail.Meanwhile,in the aspects of increasing power transmission capability of the grid-connecting channel and improving post-fault voltage recovery level,the enhancement effect of FACTS devices on power grid transient stability is researched.Finally,the influences of FACTS devices on electromagnetic transient are analyzed in the viewpoints of suppressing system overvoltage and secondary arc current.
