“十五”西电东送广东电网受电能力研究

Study on ability for Guangdong network to receive electric power from west to east in the Tenth Five-Year Plan period

为配合国家西部大开发战略,“十五”期末贵州、云南、天生桥及三峡等将向广东送电10000MW,南方4省将形成世界上最大的交直流互联电网。有关的系统研究表明,在一定的电网结构下,影响广东电网受电能力的关键因素是受端电网的无功电压支撑及交直流系统相互配合问题。

In order to coordinate the great developing western china strategy,10million kilowatts of electricity will be transmitted from Guizhou,Yunnan,TianShengQiao and Three-Gorges to Guangdong Province by the end of the Tenth Five-Year Plan period(2001～2005).The4Provinces of southern china will form the largest AC-DC interconnecting power network on the world.According to the study of related system,for the certain structure of power network,the key factor influencing the ability for Guangdong net-work to receive electric power is the support of reactive power at the receiving power network and the cooperation of AC system with DC system.
