摘要

火电机组协调控制常用的微分功能为一阶线性微分

该控制方式对于机组负荷变动的模式识别和微分跟踪均具有较大迟延。本文主要分析了控制系统的一阶微分和跟踪微分

对不同信号的微分跟踪特性进行对比。结果表明无论是在跟踪快速性和抗干扰能力等方面

跟踪微分均有不可替代的优良特性。实际运行结果表明使用跟踪微分后

机组主要参数控制品质明显提升。

Abstract

For design of coordinated control system in thermal power units

first order differential is mostly used. However

there is a heavy time-delay difficulty would be overcome by this function when it faced the realistic use for pattern recognition and differential tracking. In the present work

another differential tracking method is developed and compared with the conventional first order differential. The result shows that

the new differential tracking method has a good quality in both fast differential tracking and overcoming noise disturbing. Moreover

when the new method is adopted

the controlling quality of main parameters of the unit is improved dramatically.
