摘要
热力系统分析理论是热力系统性能监测和热经济性诊断的有效工具。依状态空间法将小扰动理论引入热力系统分析中,借助于矩阵性能计算模型,提出了一种新的耗差分析方法。这种方法利用汽轮机在线监测数据,其计算精度高,适于工程实际应用,对机组性能监测和运行优化有重要意义。
The analytic theory of thermodynanlic system is effective for the performance monitoring of themlodynamic system and diagnosis of thermo - economics. By means of the state space method, the theory of small disturbance is introduced to the analysis of thcrmo dynamic system of a power plant. Based on the matrix equation of the cycle function method and the actual online monitoring data of turbines, we put forward an effective method of analyzing energy conservation in power plants. The results show that the new method has higher precision and is suitable to engineering application. This method will play an important role in the performance supervision and the operational optimization of power plants.
