基于机组负荷指令的水、风指令产生回路的方法
摘要：
本发明公开了一种基于机组负荷指令的水、风指令产生回路的方法，包括如下方法：机组负荷指令通过折线函数f(x)得出锅炉相应指令初始值后分别形成三种回路：第一回路：机组负荷指令、折线函数f11(x)、给水量指令初始值、给水控制系统；第二回路：机组负荷指令、折线函数f12(x)、一次风风压指令初始值、一次风压力控制系统；第三回路：机组负荷指令、折线函数f13(x)、风量指令初始值、送风控制系统。本发明的方法可以准确的控制锅炉的入炉煤量、给水量以及送风量，提升了机组的运行效率，提高了机组的安全性和经济性。
摘要（英）：

The invention discloses a method for generating loops based on a water and wind command of a unit load command. The method includes the steps that the unit load command obtains corresponding boiler command initial values through a polygonal function f(x) and then forms the three loops, namely the first loop including the unit load command, a polygonal function f11(x), a water feeding amount command initial value and a water feeding control system; the second loop including the unit load command, a polygonal function f12(x), a primary wind pressure command initial value and a primary wind pressure control system; and the third loop including the unit load command, a polygonal function f13(x), a wind amount command initial value and a wind feeding control system. By means of the method, thecoal feeding amount, water feeding amount and wind feeding amount of a boiler can be accurately controlled, the operation efficiency of a unit is improved, and safety and economy of the unit are improved.
