基于小扰动理论的火电厂机组耗差分析

Energy-loss analysis of power plant units based on theory of small disturbance

引入系统工程的观点,以基于热力系统分析理论的小扰动理论为基础,借助于矩阵性能计算模型,提出了一种耗差分析方法。该方法利用汽轮机在线监测数据,计算精度高,适于工程实际应用。最后,通过实际例子对该方法进行了验证。

A new energy-loss analysis method is suggested based on the analytic theory and theory of small disturbance. According to the state space method, the view of system engineering is introduced into this method. The calculation model of matrix equation property is adopted. This method is based on the actual online monitoring data of turbine. An example is presented to illustrate the validity of the theory.
