Abstract: Aiming to address the lack of cycle pump management in CCGT power plants, a cycle pump optimization management system for CCGT power plants is developed. Based on the optimization model, the system can adjust the pump operation mode, according to the change of the unit load, heating quantity and the weather conditions, to realize the optimized operation of the pump. The system also builds the unit characteristic database, which facilitates the model modification and maintenance after the unit maintenance. The system has been applied in a 200 MW combined cycle unit successfully, which is positive on reducing auxiliary rate, promoting energy saving and consumption reduction, and improving the economy of the unit. The successful practice demonstrates its broad application prospects.

Key words: Gas-steam combined cycle unit, circulating water pump, optimized scheduling, energy saving and emission reduction, management system
