摘要/Abstract

摘要： 针对燃气-蒸汽联合循环机组循环水泵运行管理较为缺乏的现状，设计并开发了燃气-蒸汽联合循环机组循环水泵运行管理系统。该系统基于循环水泵优化模型，能够根据机组负荷、抽汽量以及外部环境条件的变化，对循环水泵的运行方式进行及时调整，实现循环水泵优化运行指导；系统还构建了机组特性数据库，便于对机组检修后模型特性关系的修正与维护。该系统已在某200 MW级联合循环机组中得到成功投运，对降低厂用电率，促进节能降耗，提高机组经济性有着积极作用，具有广阔的应用前景。

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
