供热抽汽机组间电与热负荷的分配优化研究

Optimization Research of Heating Extraction Steam between Units Power Supply and Heating Load Distribution

针对华电能源哈尔滨第三发电厂抽汽供热机组的特点,研究分析了机组电与热负荷优化分配问题。以提高机组经济性为原则,通过将供热机组的耗差分析结果引入热、电负荷分配系统中对实验热耗进行修正,以解决机组的实际热耗获得问题,然后采用非线性规划和遗传算法相结合的优化方法进行供热机组间的热、电负荷分配,从而最大限度地挖掘经济运行的潜力,真正实现节能增效。

According to the third power plant of huadian power energy Harbin extraction steam heating units of the characteristic, the research analysised unit electric and heating load allocation problem. In order to improve the unit econo- my for the principle, heating unit consumption by poor analysis results into thermoelectric load distribution system in the modification of heat consumption, in order to solve the actual problem for the heat consumption, then the nonlinear pro- gramming and genetic algorithm with the combination of methods of optimization heating units of thermoelectric load distri- bution between, so as to maximize the mining of economic operation of the potential and realize the energy saving efficiency.
