摘要

目前

国内电站大部分选择性催化还原(SCR)脱硝系统喷氨装置喷氨调节阀自动控制均存在一定的问题。本文通过深度主元分析

阐述了机组SCR脱硝系统入口NO_x质量浓度非线性模型的构建方法

同时利用该方法构造的模型以及模糊调节和时滞补偿控制

发展了新型的喷氨控制策略。运行控制结果表明

在动态和稳态过程中

烟囱出口NO_x质量浓度均能长时间稳定地控制在设定值附近

有效解决了SCR脱硝系统喷氨自动投入的问题。

Abstract

At present

most of the automatic control of ammonia injection valve in domestic SCR ammonia spraying system exist certain problems.To solve this problems

this paper expounded the establishment method for a non-linear predictive model for NO_x concentration at the SCR system inlet

on the basis of deep component analysis.Moreover

combined with the fuzzy control and time delay compensation method

this model was applied to develop a new control strategy for ammonia injection.The result shows that

in both steady and dynamic state of the unit

the NO_x concentration at the stack outlet can be controlled within the range close to the setting value for a long time.So the problem of automatic operation of the ammonia injection in SCR system was effectively solved
