Abstract：Through the comparison of the AGC performance indexes under two different modes of the #5 unit’s pure condensing and cogeneration of the Hebei Xibaipo Power Plant，the optimization scheme of the unit coordinated control system is explored in this paper. Through the optimization of the coordinated control logic of the unit sliding pressure curve and the boiler main control static feed forward， the control parameters are adjusted for a long time，so that the AGC performance index of the unit is greatly improved in the cogeneration mode，and the economic benefit of the company is guaranteed and the market competitiveness of the company is further promoted.
