介绍了一套由多层次控制模块组成的,可实现多冗余、多策略控制的适用于小型链条炉控制的计算机监控系统。针对锅炉和供热管网组成的供暖系统大滞后、强惯性和严重非线性的特点,在锅炉负荷主控制回路中,采用Fuzzy-PI双模控制器,并首次用模糊控制理论研究分室布风控制。控制系统中,常规控制与智能控制并存。该系统可对锅炉、热网组成的供暖系统实时监测,并跟随热网负荷的变化及时调节锅炉的出力,通过自动调节引风、鼓风和给煤量以及各分室风门开度,维持锅炉在最佳工况工作,且可实现不停炉除灰。在满足供暖要求的同时,达到节能降耗的目的。该系统已成功应用于北京西城区某锅炉房6t/h供暖锅炉的控制中。
A set of multi-level control module is introduced to realize multi-redundancy and multi-strategy control of computer monitoring system suitable for small chain furnace control. For boiler and heating pipe network heating system composed of large lag, strong inertia and serious non-linear characteristics of the boiler load control loop, the use of Fuzzy-PI dual-mode controller, fuzzy control theory for the first time with the research room control. Control system, conventional control and intelligent control co-exist. The system can be boiler, heating network composed of real-time heating system monitoring, and to follow the heat load changes in the timely adjustment of the boiler output, by automatically adjusting the induced draft, blast and coal supply and the opening of the sub-room damper to maintain the boiler at Best working conditions, and can achieve non-stop ash furnace. To meet the heating requirements at the same time, to achieve the purpose of energy saving. The system has been successfully applied to a boiler room in Xicheng District, Beijing 6t / h heating boiler control.
