机组自启停系统的逻辑设计分析
摘要
针对火电机组自启停系统(APS)功能
分析了APS的设计原则
表明APS断点设计是实现机组"一键启停"的关键。以某机组为例
介绍了APS的结构、断点、基本功能模块以及模拟量控制回路等设计方案。实际应用表明
APS大大减少了机组起、停操作
提高了机组自动化控制和安全运行水平。
Abstract
Directing against the requirements of automatic procedure start-up/shut-down(APS) system of units
the break-point design of APS is a key point for realizing "using one key to start-up/shut-down the unit".Taking one unit as example
the design scheme of structure for APS
break points
and basic function modules
as well as the control circuits of simulated quanties have been presented.Practical application shows that the said APS system of unit can greatly decrease operations in the process of start-up/shut-down
enhancing the automatic control and safe operation level of units.
