摘　　要：三T接线和双回链式接线是未来广东110kV电网主要采用的接线方式。文章介绍了年费用法和单位负荷年费用法,并对这两种接线方式的经济性进行了比较研究。研究表明:影响三T接线和双回链式接线经济性的不确定因素较多,在文中给定的条件下,这两种接线方式在经济方面对比较为接近,经济性可作为接线方式选择的参考因素,但不宜成为决定因素。Three T connection and double circuits chain connection are the prime connection modes in future Guangdong 110 kV power girds.This paper introduces annual cost method and annual cost per load method to investigate the economy of these two connection modes.The investigation shows that there is little difference in economy comparison between the two connection modes in certain scenarios due to many uncertain factors.Economy is the reference other than the decisive factor in choosing connection mode.
