A study on the Load Distribution of a Thermal Power Plant Peak-shaving Unit from a Cost-effective Viewpoint

本文探讨了火电调峰机组在负荷分配中合理使用燃料降低能耗的问题。采用数学规划的方法,建立了京津唐电网火电机组调峰负荷分配的数学模型。将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。为制订调峰的优化方案和节能降耗提供了有效的手段。

In this paper is discussed the problem of achieving a rational use of fuel and reduction of energy consumption during the implementation of load distribution of a thermal power plant peakshaving unit. By the use of optimization techniques a nonlinear programming mathematical model has been set up for use in the load distribution of a peak-shaving unit of Beijing-Tianjin—Tangshan Power Network. An optimization calculation has been conducted with electric power supply/coal consumption being taken as an objective function. The resulting optimization curves can serve as a helpful and effective means for optimizing peak-shaving operations, thereby attaining sizable energy-saving effects.
