摘要
机组自启停控制系统(APS)是热工自动化技术的最新发展方向之一。以某国产600 MW机组DCS系统改造为实例,介绍了在老机组改造项目中设计和应用APS系统的方法,并重点探讨了功能组设计和闭合控制回路投自动等关键技术问题。APS系统在给运行人员操作指导的基础上,还可以进一步减少人为干预,提高机组自动化水平,从而达到加快机组启停的目的。
APS is one of the latest development directions of thermal automation technology. Taking the DCS retrofit for a domestically-made 600 MW unit as an example, the design and application of APS to retrofit for aged units are presented, anti the essential technical issues such as function group design and the automation of closed loop control circuit are emphatically discussed. In addition to providing operational guidance for operatives, the APS can also limit interference from human, which improves the units＇ automation level and helps the units achieve quick start-up and shut-down.
