电站机组热经济性在线管理系统的开发与应用

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

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。

On the basis of the DAC system in the power plant, a steam turbine set energy loss detection system based on eombinative 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.
