基于MACS的烧结余热发电工程控制系统设计

Design of control system of sintering waste heat power generation project based on MACS

某钢铁有限公司烧结余热发电工程采用杭州和利时公司的MACS控制系统,主要对温度、转速、压力等相关参数进行自动控制和实时监控。在软件设计环节,汽轮发电机连锁控制中温度采集采用DE功能块防止误跳变,首出报警控制采用DEH信号延迟功能防止误报警等具体方法。事实证明,和利时MACS系统能提高发电生产过程的自动化程度、企业的生产效率,降低员工的劳动强度。

In the steel company,the sintering waste heat power generation project adopts the Hangzhou Hollias MACS control system.The related parameters such as temperature,speed,pressure etc are controlled and monitored in real time.This paper mainly discusses the design link of the software.DE function blocks are used to prevent the false jump in the temperature acquisition in the chain control of the turbogenerator.The first out alarm control uses the DEH signal delay function to prevent the false alarm.In fact,the Hollias MACS system can improve the degree of automation of power production process,which has improved the production efficiency of the enterprise and reduced the labor intensity of the employees.
