单元机组中按给定模型实现机炉负荷协调的设计方法

就目前看,前馈——反馈复合控制系统仍是单元机组实现机炉负荷协调控制的基本型式,但设计方法还不甚完善。本文选取协调关系以Moore系统为基础,依据解耦理论建立了单元发电机组按给定模型实现机炉负荷协调的设计方法。设计实例及其仿真结果表明,这个设计方法是合理、可行的。

A Design Method Realizing Boiler-Turbine Load Coordination in Accordance with Setting Models for Unit Generator Sets

Feedforward-feedback compound control system is srill the typical construction realizing boiler-turbine load coordination control for unit generator sets. But its design method is still imperfect. Therefore two formulas of the coordinate relationship are selected and a design method is presented in this paper, which realizes the boiler-turbine load coordination control in accordance with setting models. In this method, the decoupling theory is applied as a fundamental theory and the Moore system is used as a basis construction of this system. The design example selected and its simulation results show that this method is reasonable and feasible.
