Control system of nuclear power unit, automatic diagnostic method and subsystem thereof

Abstract

The inventive embodiment discloses a control system of a nuclear power generating unit and an automatic diagnostic method and a subsystem thereof. The method comprises the following steps that the equipment and/or system information of the nuclear power generating unit is obtained; the equipment and/or system information is calculated through a preset diagnosis logical formula to obtain the function state diagnosis result of the equipment and/or system; in accordance with the function state diagnosis result of the equipment and/or system, the operator needs to adopt corresponding operation measure aiming to the function state; the corresponding operation measure aiming to the function state adopted by the operator is displayed on a display device. The inventive embodiment is able to provide the operator with the function state diagnosis result of the equipment and/or system quickly and accurately, and is able to guide the operator to adopt the corresponding measure.

Description

technical field [0001] The invention relates to a nuclear power unit, in particular to a control system of a nuclear power unit, an automatic diagnosis method and a subsystem thereof. Background technique [0002] The control system of the nuclear power unit of the nuclear power plant is an important part of the nuclear power plant. The safe, reliable and economical operation of the unit depends to a large extent on the performance level of the control system of the nuclear power unit. The control system of nuclear power units has gone through three stages. The first stage is a control system based on analog combined unit instruments. The analog instruments are controlled by components based on small-scale integrated circuit operational amplifiers. The logic instruments are controlled by hard logic circuits such as relays. The control system needs The number of instrument control devices is large, the operation, operation, management and maintenance tasks are heavy, and mos...

Problems solved by technology

In various operating conditions of nuclear power units (especially in the case of accidents), there is a large amount of data information that will be fed back to the control room of the nuclear power unit. It will take a lot of time to identify information one by one through the operator, especially when the nuclear power unit appears When abnormalities need to be quickly intervened and processed by operators, the influx of a large amount of information requires operators to effectively identify and take correct measures to quickly control nuclear power units. The diagnostic technology of the main control system is mixed. The amount of information must be manually analyzed and judged by the operator for a large amount of time, and it is easy to cause errors due to human errors.
