Abstract

According to multi-borders, nonlinear, time-varying characteristics of the thermal system of large coal-fired power units, the relationships between the operating parameters and the energy consumption characteristics are very complex. The key operating parameters which influenced the standard coal consumption rate are obtained based on rigorous theoretical analysis. On this basis, features are extracted from the characteristics to be used as inputs of s-SVR for training and testing. Energy consumption distribution model under full conditions of large coal-fired power units based on aforesaid method has high precision.

基于s-SVR的火电机组能耗特性分析
大型火电机组热力系统具有多边界、非线性、时变的特点,其运行参数与能耗特性之间的关系十分复杂。通过严格的理论分析,得出了影响标准煤耗率的关键运行参数。在此基础上,从特征中提取特征作为s-SVR的输入进行训练和测试。基于上述方法建立的大型燃煤机组满工况能耗分布模型具有较高的精度。
