- Abstract
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.
