Economic Experimental Analysis and Study of Gliding Pressure Operation of Steam Turbine Sets

Taking some power plant turbine set 2 of state power as a example,through make the optimization experiments of gliding pressure turbine sets,this article compares and analyses the economy of turbine sets under different operating mode and under different power loads,and ascertain the economy of turbine of gliding pressure operation mode in the condition of valve point gliding pressure and some of the valve widely open,and give out the optimal curve of gliding pressure operation mode.Furthermore,this paper discusses valve control strategy in the gliding pressure operation mode,and come to a conclusion that when use the complex gliding pressure operation,it can improve the economy of the entire units,increase the service life of units.It is important significance that optimization and study of gliding pressure operation of steam turbine sets impacts on thermal economy,as well as saving energy on site.
