Nuclear power plant, water level control method and system for steam generator

Abstract

The invention is applied to the field of nuclear power control, which provides a nuclear power plant and steam generator water level control method and system thereof. The method includes the following steps: acquiring the parameter and equipment running status related to the steam generator water level control; outputting the operation entrance related to the steam generator water level control and the acquired parameter and equipment running status related to the steam generator water level control to a steam generator water level control main interface; receiving the input steam generator water level control instruction from the operations entrance of the steam generator water level control main interface, and executing the steam generator water level control operations corresponding to the steam generator water level control instruction. The inventive embodiment outputs the information related to the steam generator water level control to a same man-machine interactive interface, so that operators can intuitively, comprehensively and fast acquire parameters and judge the reason that the exceptional steam generator water level occurs, and rapid intervention can be realized by the man-machine interactive interface.

Description

technical field [0001] The invention belongs to the field of nuclear power control, in particular to a water level control method and system for a nuclear power plant and a steam generator thereof. Background technique [0002] The pressurized water reactor nuclear power plant is mainly composed of three parts: the pressurized water reactor, the primary loop system and the secondary loop system. The nuclear fuel in a pressurized water reactor generates heat through nuclear fission. The heat released by nuclear fission is taken out of the reactor by the high-pressure water flowing through the primary circuit system in the reactor, and the heat is transferred to the water in the secondary circuit system in the steam generator. The steam generated after the water is heated drives the steam turbine, and the steam turbine Then drive the generator to generate electricity. [0003] In a pressurized water reactor nuclear power plant, the water level of the steam generator must be ...
