Abstract :
Analyze temperature and stress fields of turbine´s rotors in high-medial pressure cylinders by two-dimensional stress modal of Finite Element Method (FEM), supply allowed thermal stress range to Auto Turbine Control (ATC) system. According to changing trend of thermal stress, it can regulate startup speed of unit, and realize automatic control of startup process for optimal scheme so as to improve security and economy of operation. We have develop ATC Module by Hollysys DCS software for 4*300MW Units in YAXI Power Plant, GuiZhou, China and realize the application of thermal stress control and optimization during the whole operation process.
