330MW循环流化床机组CCS控制系统分析与应用

摘要

Combining with the # 1 and # 2 CFB boiler already operated in Inner Monglia Jinghai Coal gangue Power Plante. This paper analyzes the structure of coordinated control system, and related control scheme and logic relation is presented,and introduces the methods to deal with the challenging long delay and high order inertia control. The frequency regulation has been mentioned; The press deviation dragging load loop has been designed in order to limit the response speed of turbine valve) The Indirect Energy Balance ( IEB) strategy and Fuel feedforward has been used. On-site experiments in dicate that all the designed logic on CCS are effective and the control effects of CCS are ideal.%结合内蒙古京海煤矸石发电有限责任公司已经投运的#1、# 2CFB机组,分析机炉协调控制系统的控制结构,介绍相关的控制策略和逻辑关系,并针对CFB锅炉的大迟延、高阶惯性的控制难点介绍协调回路下的一次调频功能、汽机侧的压力偏差回拉功率回路,以及间接能量平衡加燃料前馈的控制策略.现场实验结果表明,所设计的控制逻辑工作是有效的,协调系统控制效果比较理想.
