电站机组热经济性在线管理系统的开发与应用

在电厂现有数据采集系统DAS的基础上,开发基于Web发布的C/S(Client/Server)和B/S(Browser/Server)混合体系结构的机组能损实时监测系统。结合锦州电厂汽轮发电机组的实际运行情况,对机组的各项热经济性指标进行实时监控、分析计算,提高机组运营水平及经济效率,在客户端为公司领导、运行人员以及考核人员提供了考核评价的平台。

Development and application of on-line heat economics system of thermal power unit

On the basis of the DAC system in the power plant,a steam turbine set energy loss detection system based on combinative structure of C/S and B/S was developed.With the practical instance of the thermal power unit in Jinzhou power plant,this paper carried out calculations on the variable rated performance of the steam-gas turbine combined operation,which was used to raise the efficiency of a combined cycle plant to achieve the largest possible economic profit.It offers a checking platform for the leaders,executors and assessors in the client.
