Fault detection method applied to nuclear power plant system

Abstract

The invention relates to fault detection technology, and provides a fault detection method applied to a nuclear power plant system aiming at the defects of time consumption and labor consumption existing in fault clearance schemes of the conventional nuclear power plant systems. The method comprises the following steps of: setting a root node of a fault tree as an operating node; determining a possible fault node based on a logic gate for connecting the operating node and each sub-node and fault probability; acquiring operating parameters of equipment; judging whether the fault node is a bottom node of the fault tree when judging that fault exists in the equipment corresponding to the possible fault node according to fault conditions associated with the possible fault node and the operating parameters; if so, outputting the equipment which corresponds to the possible fault node and serves as a fault point; and otherwise, setting the possible fault node as the operating node and returning to the second step. The technical scheme provided by the invention completely automatically runs during the clearance of failed equipment, and the clearance speed is high, so the method can actually save time and labor.

Description

technical field [0001] The invention relates to fault detection technology, more specifically, to a fault detection method applied to nuclear power plant systems. Background technique [0002] The safe operation of nuclear power plant systems is of paramount importance. [0003] In the actual application process, in order to ensure the safe operation of the nuclear power plant system, the power plant management unit has taken various necessary measures so that an alarm can be issued in time when an operation failure is detected. However, the nuclear power plant system is very large. Even if an alarm is detected, it takes a lot of time to carefully investigate the problematic part, and the investigation requires the participation of many production departments. If the alarm prompt causes the power station to stop running, a lot of time wasted in troubleshooting the problem will inevitably bring difficulties to the power supply in the relevant area. [0004] Therefore, there...
