An integrated control system for a deaerator process of a combined thermal power plant and a method for the same are provided to adjust all kinds of factors and simplify the tuning of a control system by realizing integrated control. An integrated control system for a deaerator process of a combined thermal power plant includes a deaerator process unit(1), low-ranking control devices(5), a DB handling device(70), a monitor control device(80), and an integrated high-ranking control handling device(100). The low-ranking control devices detect a controlled variable having the water level, the flux, and the pressure of each storage tank of the deaerator process unit to control an operation of the corresponding storage tank. The DB handling device collects all kinds of the controlled variables from the low-ranking control devices to save the controlled variables. The integrated high-ranking control handling device transmits a manipulated variable to the low-ranking control devices through The DB handling device. The monitor control device manages and controls various processes of a deaerator and selects low-ranking control or integrated high-ranking control which is as an operation mode of the deaerator process unit by collecting data saved and collected in the DB handling device. |
