Alarm filtering method and system of nuclear power plant, medium and electronic equipment

Abstract

The invention discloses an alarm filtering method and system of a nuclear power plant, a medium and electronic equipment, and is suitable for nuclear power plant equipment function alarm. The alarm filtering method comprises the following steps of: S1, pre-establishing a causal relationship among all alarm events; S2, after the alarm events are received, analyzing and determining a causal relationship of the received alarm events according to the pre-established causal relationship among all the alarm events, and acquiring at least one of a reason alarm event, a result alarm event and an unknown alarm event; and S3, after analysis processing, reserving all reason alarm events. Under the transient or accident working condition, the number of intermediate alarms of the nuclear power plant can be effectively reduced, useful alarms can be reserved as little as possible, the workload of an operator is reduced, fault points can be quickly positioned, the operator is helped to identify and judge common-mode faults and multiple independent faults, the operator is helped to effectively control a unit as early as possible, and event deterioration is prevented.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant alarms, in particular to an alarm filtering method, system, medium and electronic equipment for nuclear power plants. Background technique [0002] As a kind of warning information with sound and light reminder function, the nuclear power plant alarm is used to inform the operator that the state parameters of the power plant deviate from the normal range, equipment failure, equipment state change or will deviate from the normal operation, to remind the operator that the state of the unit is abnormal, and require The operator prompts to take appropriate action through the alarm to stabilize or guide the unit to a controllable state. [0003] In nuclear power plants, when the state parameters deviate from the normal range or the state of the equipment changes, an alarm signal will be issued. In transient or accident conditions, there are many related alarms. A series of related alarms ar...

Problems solved by technology

[0003] In nuclear power plants, when the state parameters deviate from the normal range or the state of the equipment changes, an alarm signal will be issued. In transient or accident conditions, there are many related alarms. A series of related alarms are triggered by a parameter or a change in the functional state of the equipment. Dozens of related alarms may appear at the same time, the number is relatively large, and the operator needs to analyze dozens of alarms to determine the fault point, which is very unfavorable for the operator to find the fault point

[0004] Although there are existing alarm suppression methods that use some of the same functions, the alarm suppression function is mainly used for high-state suppression of low-state alarms with some of the same functions (such as high and high liquid level alarms to suppress high alarms), and most of the alarms cannot be analyzed. Analysis of a few alarms has relatively large limitations
