| 摘 要： | 针对大型火电站的复杂热力系统，以电厂现有的数据采集系统（DAS）为基础，利用热力系统汽水分布矩阵方程建立火电站热力系统模型，并通过矩阵比较的办法统一分析加热器侧各项因素对能损的影响，给出诊断结果，最终实现实时监测诊断各热力的运行状态，本系统采用先进的可视化开发平台Borland Delphi 3.0实现，结合现场进行了试验和验证，结果表明该系统具有较高的准确性和可靠性。

| Abstract: | On the basis of DAS in coal-fired power plant, this paper sets up a thermal system model through thermal system water-steam distribution matrix equation. It uses comparison of matrix to analyze distribution and quantity of every energy loss for factors of water side, and acquires the result of diagnosis. Operational condition of every thermodynamic equipment can be monitored. The system is completed by Delphi, and is tested onsite. The result shows that the system has high accuracy and reliability. |
