Research on Start-up Technology of High and Low Position Steam Turbines for 1 350?MW Units
This project relies on the research on the start-up technology of the 1350 MW high and low position steam turbines of the Pingshan Phase Ⅱ Power Plant in Huaibei,Anhui.It optimizes the cold and extremely hot start-up methods of the units,ensures the stability of the start-up of high and low position steam turbine units under different working conditions,and avoids the problem of load distribution when high and low position units start simultaneously.The original control logic design framework has been optimized,especially in the high and low positions during extreme hot start,to shorten the grid connection and load time after extreme hot start,while preventing reverse power protection actions of high and low level machines and load fluctuations caused by cylinder cutting after load.
