Device and system for monitoring and displaying normal operating condition of unit of nuclear power plant

Abstract

The invention relates to a device and a system for monitoring and displaying normal operating condition of a unit of a nuclear power plant. The nuclear power generating unit has a plurality of operating modes; on a display device, a monitoring module is imported aiming at one operating mode; the monitoring module comprises four units displaying simultaneously, namely a trend tracking unit, a value display unit, a device state unit and an accident condition indication unit. The technical scheme of the invention is that: a reactor operating mode is dominant so as to perform a system monitoring design; according to the change of the normal operating state of the nuclear power generating unit, for a certain working mode, frequent and intersystem monitoring and analysis are needed; parameters and equipment to be monitored are concentrated in a unified monitoring module and displayed through the display device so as to facilitate the monitoring and operation of the total state of the nuclear power generating unit; and the defect of a DCS (digital control system) in the aspect of intuition is overcome, the advantages of a control room of the DCS are fully played, and the safe and stable operation of the nuclear power plant is ensured.

Description

technical field [0001] The invention relates to a nuclear power plant unit, more specifically, to a monitoring and display device and system for the normal operation state of a nuclear power plant unit. Background technique [0002] The pressurized water reactor nuclear power plant is mainly composed of a pressurized water reactor, a primary loop system, a secondary loop system, and peripheral auxiliary systems. Pressurized water reactors use low-enriched uranium as fuel and light water as the coolant and moderator. The heat released by the fission of the core of the pressure vessel is taken out of the reactor by the high-pressure water flowing through the primary loop system inside the reactor, and the heat is transferred to the water of the secondary loop in the steam generator. The steam generated after the water is heated drives the steam turbine, and the steam turbine drives the generator to generate electricity. If the steam turbine generator unit shuts down unexpecte...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that, in the above-mentioned DCS (Digital Control System) control room of the prior art, unit status monitoring can only be carried out according to the system screen, which is unfavorable for understanding the overall status of the nuclear power unit, and for cross-system monitoring execution It is very cumbersome and other defects, providing a monitoring and display device and system for the normal operation status of nuclear power plant units
