电厂机组电热负荷分配对厂内发电气耗率的影响分析

Analysis on Influence of Electricity and Heating Load Distribution of Power Plant Units on Gas Consumption Rate of Electric Power Generation in Plant

针对吴江电厂运行情况进行电厂热电比对发电气耗的影响分析,得出:电厂发电气耗与热电比之间成反比;需通过合理分配电厂不同机组间的电热负荷,使得2台机组的热电比均处于较高值,才可使得电厂的发电气耗为最低值;还可利用多热源优化厂内电热负荷的分配,促使电厂发电气耗降低。

According to the operation of Wujiang Power Plant,this paper analyzed the impact of the power plant's thermal power ratio on the gas consumption of electric power generation.It is concluded that the power consumption of the power plant is inversely proportional to the thermal power ratio;it is necessary to reasonably allocate the electrical and thermal load between different units of the power plant to make 2 units Only when the heat-to-electricity ratio of the power plant is at a high value can the power consumption of the power plant be minimized;multiple heat sources can also be used to optimize the distribution of the electric and heat load in the plant,so as to reduce the power consumption of the power plant.
