Steam generator water-level control method and device and nuclear power plant of nuclear power generating unit

Abstract

The invention is applied to the field of nuclear power control and provides a steam generator water-level control method, device and nuclear power plant of a nuclear power generating unit. The method comprises the following steps of: detecting a parameter associated with steam generator water-level control; obtaining an operation inlet and an equipment operating state associated with the steam generator water-level control; outputting the detected parameter and the obtained operation inlet and equipment operating state to a steam generator water-level control main interface; carrying out functional attribute classification on the detected parameter and the obtained operation inlet and equipment operating state; setting the layout of the steam generator water-level control main interface according to a result of the functional attribute classification; and receiving a steam generator water-level control command and executing the corresponding steam generator water-level control operation. In the embodiment, after the information associated with the steam generator water-level control is functionally classified, the steam generator water-level control main interface is laid out, so that an operator can quickly obtain the parameter in an overall way and realize quick interference.

Description

technical field [0001] The invention belongs to the field of nuclear power control, and in particular relates to a water level control method and device for a steam generator of a nuclear power unit and a nuclear power plant. 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 ...
