装机容量为4200兆瓦,预计2011年全部建成的小湾电站,是云南省实施西电东送的主力电源,也是满足云南本省用电需要的重要电源。为满足小湾电站电力送出、加强云南电网消纳小湾电力的能力,建设小湾电站送出及云南主网配套500千伏输变电工程势在必行。为配合小湾电站工程首台机组于2009年10月31日投产发电的总进度要求,云南电网公司启动了小湾电站500千瓦送出线路工程建设。当前,小湾电站500千伏送出工程已进入施工设计阶段。
The installed capacity of 4200 MW, is expected to be completed in 2011 Xiaowan power station, is the implementation of the main power supply in the province from west to east, but also to meet the needs of Yunnan Province, an important power supply. In order to meet the power supply of Xiaowan Power Station and strengthen the ability of Yunnan Power Grid to absorb Xiaowan Power, it is imperative to construct a 500-kilovolt transmission and transformation project for Xiaowan Power Station and Yunnan main network. In line with the overall requirements of Xiaowan Power Station’s first unit put into operation on October 31, 2009, Yunnan Power Grid Company initiated the construction of a 500-kilowatt transmission line at Xiaowan Power Station. At present, the Xiaowan Power Station 500 kV project has entered the construction design phase.
