摘要(Abstract):
针对配置炉水循环泵的超超临界机组给水系统的湿态控制要求,对贮水箱水位控制、湿态给水流量控制以及湿态转干态控制进行研究,提出一种面向自治对象的超超临界机组湿态给水控制策略。设计模块化的炉水循环泵出口调节、给水旁路调节以及汽动给水泵变工况自适应切换的集成控制策略,根据给水控制设备当前的运行状态和参数自主规划控制模式。应用结果表明,所设计的湿态给水控制策略能很好地满足机组湿态给水系统的复杂控制需求,为同类型机组的湿态给水控制逻辑优化及运行调试提供了参考。
In view of the requirement of wet state control for feed water system of thermal power unit with boiler circulating pump, the water level control of water storage tank, wet state feed water flow control and dry and wet state conversion are studied, and an autonomous object-oriented wet-state full-range control method for feed water system of thermal power units is proposed. An object-oriented control strategy was designed for the outlet control valve of boiler circulating pump, feed water bypass control valve and steam turbine-driven feed water pump, which can switch adaptively and run synchronously in parallel under different operating conditions.Based on the operation state and parameter self-planning control mode of feed water control equipment. The application results show that the actual operation process shows that the designed wet feed water automation control strategy can meet the needs of wet feed water system. The relevant parameters and operation curves of wet feed water control system put into operation can provide reference for logic optimization and operation debugging of wet feed water control of the same type units with boiler circulating pump.
