摘要
本文研究了枯水期三峡电厂各类运行方式下安福站合环运行的适应性,通过调整三峡开机等限制江陵站短路电流超标的控制策略,以及合理安排鄂西电网运行方式来避免安福站潮流上网和电磁环网带来的稳定风险,探讨了安福站主变合环条件。结果表明:合理安排安福站(季节性)运行方式将提升安福主变合环运行适应性,进一步提高鄂西电网枯水期间供电充裕性及可靠性。
In this paper,the adaptation level of Anfu substation closed loop operation under different operation modes of the Three Gorges power plant is studied.The short-circuit current of Jianglin substation is controlled by adjusting the the Three Gorges power operating plants,and unconscionable flow of Anfu substation is avoided by adjusting the operation mode of West Hubei power grid.The results show that reasonable arrangements of West Hubei power grid(seasonal)operation mode will enhance the adaptation level of Anfu station loop closing operation,which improves the power supply adequacy and reliability during the dry period.
