摘　　要：北方地区供暖主要利用各类燃煤锅炉所产生的热力,一个采暖季造成二氧化碳排放量达10亿t,利用核电站的热能进行抽汽供热替代传统的燃煤供热,对于减少二氧化碳排放和实现碳达峰目标具有重要意义。通过仿真软件模拟AP1000机组汽轮机发电系统回路抽汽供热对104000 m 2厂区供热,分别采用主蒸汽管道、辅助蒸汽管道和汽轮机抽汽3种方式进行供热,比较不同方式下抽汽供热对于发电量的影响并最终选出最佳抽汽位置;通过仿真结果得出采用主蒸汽管道、辅助蒸汽管道和汽轮机抽汽影响发电量分别为供热前的0.36%、0.19%和1.17%。综合比较得出厂区内进行供热时采用辅助蒸汽进行供热对于发电量影响较小。The heating in northern China mainly relies on coal-fired boilers.The emissions of carbon dioxide during a heating season reach 1 billion tons.The extract steam heating from nuclear power plants instead of traditional coal-fired heating is of great significance for reducing CO 2 emissions and achieving carbon peak targets.Through the simulation software,the AP1000 unit steam turbine power generation system loop extraction heating is used to heat a plant area of 104000 square meters.The heating is accomplished by extracting steam at three major locations:main steam pipes,auxiliary steam pipes and the turbine.The optimal extraction positions are located after a comparison of the electricity output changes under three heating strategies.The simulation results show that the extraction heating through the main steam pipes,the auxiliary steam pipes and the turbine causes the electricity output to decrease by 0.36%,0.19%and 1.17%respectively after heating.A comprehensive comparison of the data suggests the auxiliary steam extraction heating in the plant area has the lowest impact on the power generation of nuclear power plants.
