摘　　要：随着电力需求的不断发展,广东电网短路电流水平迅速提高。超导限流器对电力系统的正常运行无影响,一旦发生故障能够立即投入限制短路电流,达到对短路电流的抑制。以2015年作为研究水平年,以广东规划电网为研究对象,对广东500 kV电网短路电流水平进行计算分析。综合考虑超导限流器安装对短路电流的抑制效果、对电网发展的适应性及对电网运行的影响等方面来进行其在广东电网应用选点方案的研究,推荐西江站、东纵站及深圳站考虑作为加装超导限流器的站点,有力降低广东电网短路电流水平,促进广东电网发展。With the continuous increase of power demand, the short-circuit current level of the power system increases rapidly in Guangdong power grid. The superconducting fault current limiter does not affect the normal operation of the power system, but once a fault occurs, it can be put into use to limit the short-circuit current immediately. This paper, taking the planned power grid in Guangdong in 2015 as the research object, calculates and analyzes the short-circuit level of the Guangdong 500 kV grid. Comprehensively considering the the inhibitory effect of the superconducting current limiter on the short-circuit current, its adaptability to the grid development and impacts on the grid operation, the paper studies the suitable installation proposals of the superconducting current limiter in Guangdong power grid. and recommends Xijiang Substation, Dongzhong Substation and Shenzhen Substation as suitable sites for installation of the superconducting fault current limiter.
