摘要:

随着特高压电网的快速发展,特高压变电站的电气主接线对电网的安全可靠运行起着越来越重要的作用,因此选择合适的电气主接线是特高压变电站建设中的一个重要课题。结合苏州1 000 kV特高压变电站的特性分析了500 kV电气主接线方案,对双母线接线和3/2接线进行了详细的技术经济比较,推荐苏州特高压变电站500 kV主接线采用双母线接线。该接线不仅能够满足电网可靠性的要求,而且调度灵活、扩建方便、占地小、投资省。

Abstract:

With the rapid development of UHV power grid, the main electrical connection of UHV substation becomes more and more important to the safe and reliable operation of power grid. Therefore, the selection of suitable main electrical connection is a key work in the construction of UHV substations. According to the characteristics of Suzhou 1 000 kV UHV substation, he 500 kV main electrical connection scheme is analyzed in this paper. The techno-economic comparison between double-bus connection and two-thirds connection is carried out and the 500 kV main electrical connection of Suzhou UHV substation is suggested to adopt the double-bus connection, which not only could meet the requirements of the reliability of power grid, but also have some advantages of flexible scheduling, convenient expansion, small occupation of land and low investment.

Key words: UHV substation, main electrical connection, reliability, double-bus connection, two-thirds connection
