摘要
本文采用最优化技术的数学理论,探讨京津唐电网的调峰运行方案,在满足电网负荷曲线的要求下,计算出调峰机组合理的启停寿命损耗,为了降低启停的经济损失,把调峰机组的供电煤耗率作为目标函数进行优化计算,得出若干优化曲线,制订了与启停寿命损耗相适应的优化方案。最后建议100MW机组实行两班制运行,解决国产200MW机组调峰特性差而难于适应电网负荷变化要求的问题。
It is discussed in this paper to apply the optimization technique method to the programing of peak-load adjusting for Beijing-Tianjin-Tangshan electric power system in north China. For reducing fuel loss in starting-stopping process the objective function is based on net coal consumption rate of power units, and optimum program may be provided by calculating optimizing curves. It is adapted to the calculation of the rational starting-stopping life expenditure of peak-load power units. This paper suggests that 100MW units in the power system operates in two shifts, and the question of domestic 200MW units' starting up characteristics not appropriate for network variable load is solved.
