Method and system for computing and displaying under computerization accident condition in nuclear power plant

Abstract

The invention relates to a method and a system for computing and displaying under the computerization accident condition in a nuclear power plant, wherein the method comprises the following steps: S1, a reading module reads the information of a sensor or an actuating mechanism of a distributed control system; S2, a logic computation module logically computes according to the read information; S3,a dynamic line module works out a logical decision path according to the read information; and S4, a display frame module reasonably organizes the logical calculated result and the logical decision path so as to be displayed. By logically computing a great deal of related information under a complicated condition, the invention provides accurate conclusion and detailed computational process for operators, utilizes the advantages of the computer control technology and the human-machine interface of an advanced master-control room to the maximum extent, and greatly improves the analysis and judging ability of the operators on complicated conditions under the accident condition; and meanwhile, the work load and the psychological pressure of the operators are relieved, and thereby the accident handling capacity and the safe operation level of the power station are improved.

Description

technical field [0001] The invention relates to computer control of nuclear power plants, more specifically, to a method and system for digital automatic calculation, judgment and display of key information in nuclear power plant accident conditions. Background technique [0002] In the routine control of the main control room of the Ling Ao Phase I Nuclear Power Plant, when an accident occurs in the power plant, all kinds of complex information is manually obtained by the operator, and a series of responsible logical judgments are made based on experience to draw conclusions, and then the operator is guided to carry out the operation. What to do next. Although the operator can draw conclusions in a short period of time through experience accumulation and rapid response, human errors are still inevitable due to high psychological pressure and complex calculation and judgment in the event of an accident. [0003] In the case of the introduction of digital advanced main contr...
