摘　　要：在300 MW汽轮机的运行过程当中,时常会出现胀差,胀差情况的出现会影响汽轮机的正常启动速度和安全运行。文章对300 MW汽轮机胀差影响因素与控制进行了分析。With the continuous development and progress of society,China’s demand for electric power is growing.To a certain extent,the development of power system determines the possibility of national construction and social progress.During the operation of 300 MW steam turbine,the infl uence of differential expansion often occurs,and the occurrence of differential expansion will affect the normal starting speed and safe operation of the steam turbine.In the power plant,300 MW steam turbine is often used.In the operation of steam turbine,once the differential expansion is found,it is necessary to analyze the specifi c factors affecting the differential expansion,so as to formulate targeted control measures to ensure the normal operation of 300 MW steam turbine to the greatest extent.This paper analyzes the infl uencing factors and control of the differential expansion of 300 MW steam turbine for reference.
