摘要
结合500kV木棉变电站输变电工程,对广东电网1 000MVA主变压器高阻抗电压参数的选择进行了研究和分析,主要对容量为1 000MVA的高阻抗变压器的短路阻抗、变压器第三绕组容量、变压器低压侧额定电压以及容性无功功率补偿装置的配置进行分析论证,为500kV木棉变电站高阻抗变压器(容量为1 000MVA)的选型工作提供依据,为广东电网未来规划建设500kV变电站的建设模式提供参考。
Combined with the transmission and transformation project of 500 kV Mumian Substation,this paper researches on the selection of high impedance voltage parameters for 1 000 MVA main transformers in Guangdong power grid.The research mainly includes the short-circuit impedance of 1 000 MVA high-impedance transformer,the capacity of the third winding,the rated voltage of transformer low-voltage side and the configuration of capacitive reactive-power compensation devices.This study provides basis for choosing 1 000 MVA high-impedance transformers of 500 kV Mumian Substation,and provides the reference construction mode for the 500 kV substations to be built in Guangdong power grid.
