探讨了一种充分考虑系统非线性特性的汽包锅炉动态模型结构,描述了动态模型的结构,并探讨了求取动态模型未定参数的方法.为构造新的协调控制系统,给出了预测负荷/压力增量的动态方程.利用这组方程,可以有效地预测机组的实发功率以及主蒸汽压力增量.仿真试验证明,在系统处于稳态时,这些预测方程同实际运行参数吻合得较好,而动态过程具有一定的超前特性 A dynamic model structure of drum boiler that fully considered the nonlinearity of the system was discussed, the structure of the dynamic model was described, and the method of determining the undetermined parameters of the dynamic model was also discussed. In order to construct a new coordinated control system, / Pressure increment of dynamic equations.Using this set of equations, can effectively predict the unit of the actual power and the main steam pressure increment.The simulation test shows that the system at steady state, these predictive equations consistent with the actual operating parameters Well, while the dynamic process has some advanced features
