600 MW 火电机组低负荷调峰的经济运行方式分析

摘要

随着电网峰谷差的日益增大，600MW火电机组调峰是其必然趋势。提高调峰机组低负荷运行的经济性，是目前亟待解决的问题。从最优化的角度出发，对600MW汽轮机低负荷调峰运行中火电机组之间负荷的优化分配、汽轮机循环水系统运行方式的优化和配汽方式的优化方法进行分析，给出了通过改变运行方式指导调峰机组低负荷经济运行的具体方法。%With the increase of the peak-valley gap in power system , it is the inevitable trend for 600MW fossil-fired generating unit to be demanded to participate in the peak load regulation operation .Enhancing the economy of fossil-fired generating units becomes a serious problem .In this paper , from the perspective of optimization , the optimization of load distribution for fossil-fired generating units , circulating water system operation mode and the steam distribution mode for 600MW steam turbine during peak shaving low load operation is analyzed ,and the specific methods of guiding the economic operating of units at peak shaving low load operation by changing the operation mode are provided .
