摘要
该文应用数学方法对多变量机炉协调非线性动态仿真数学模型的结构进行描述和分析,推导出其输入和输出之间的传递函数矩阵,在此基础上对该非线性动态仿真数学模型与线性增量形数学模型之间的内在联系,进行了分析和讨论,为在理论上解释单元机组受控对象数学模型的特性奠定了基础。通过对北仑电厂600MW单元机组的仿真试验曲线与现场实时趋势曲线进行比较,证明了文中所论之非线性动态仿真数学模型的有效性。
A non-linear simulation mathematical model is described and alyzed through the mathematical method in this paper. The transfer function matrix between inputs and outputs is deduced, and some intrinsic connections between this non-linear simulation model and the linear incremental mathematical model is presented, these connections provide the theoretical foundation for interpreting the characteristics of generating unit mathematical models. Finally, a simulation test at a 600row unit of beilun, power plant is proceeded, and by comparing simulation curves with actual real time trends of this 600mw unit, the conclusion shows this non-linear simulation model is validity.
