Title:
STEAM GENERATOR SYSTEM, STEAM GENERATOR PRESSURE CONTROL SYSTEM, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/134730
Kind Code:
A1
Abstract:
Disclosed are a steam generator system, a steam generator pressure control system, and a control method therefor. The steam generator pressure control system comprises a first control module for obtaining a pressure deviation value; a second control module for measuring and calculating a flow difference value between an outlet flow value and an inlet flow value, and then adding the flow difference value and the pressure deviation value together to obtain a first opening degree value for controlling a first valve of a water supply regulation valve group; and a third control module for measuring a steam intake pressure value of a steam turbine, and comparing the steam intake pressure value with a preset reference threshold value, so as to obtain a second opening degree value for controlling a second valve of the water supply regulation valve group. In the steam generator system, the steam generator pressure control system, and the control method therefor of the present invention, the opening and closing of a water supply regulation valve group is controlled by means of a first control module, a second control module and a third control module, such that a steam generator is controlled, thereby satisfying the requirements for both coarse regulation and fine regulation.
