株洲电厂1×310MW机组接入方案优化研究

Optimizing of Access Scheme in Zhuzhou Power Plant

基于株洲电厂现有接入点附近电源富余，而株洲电网云田～桂花断面导线截面偏小，潮流输送压力大，供电可靠性较低的情况，本文对电厂3#机组（1×310MW）提出了一种兼具可操作性和技术经济优势的接入系统优化调整方案，并对调整前后方案的供电可靠性、系统稳定水平和运行网损进行深入的比较分析，研究表明，本文提出的优化调整方案一次投资较小，实施方便，可实现电能的就地消纳，能大大提高株洲电网供电可靠性和运行经济性，远景适应性好，具有良好的可行性和显著的技术、经济优势。

On account of the surplus electric power nearby the existing access point of the Zhuzhou plant, and moreover, the transmission capacity from Yuntian to Guihua is restricted owing to the conductors’ small cross section. For Zhuzhou plant 1×310MW Unit’s integration system way, this paper proposed a new optimization and adjustment scheme, which possess favorable operability, marked technique and economic superiority. Research and calculation indicates that the new scheme could advance the power supply reliability and operation economy prominently for Zhuzhou power grid.
