Problems solved by technology

[0004] At present, the emergency diesel engines in nuclear power plants are relatively old, and the cylinder temperature inspection device equipped on site has the functions of local polling display and alarm output, but it adopts a relatively simple statistical principle for abnormal analysis, and the statistical records of data are passed through manual inspection. The method relies entirely on manual reading interval records, and does not take into account the influence of other parameters, resulting in inaccurate failure analysis results of cylinder temperature

Abstract

The invention provides a method and system for detecting the abnormity of the cylinder temperature of a diesel generator set. The method includes the following steps: collecting data of multiple parameters related to the generator set cylinder temperature; introducing the collected data of the multiple parameters into corresponding abnormality detection models to calculate the abnormity probability of each parameter; and conducting combination operation on the abnormity probabilities of the parameters to generate an abnormity probability reflecting the generator set cylinder temperature. By detecting the abnormal conditions of the cylinder temperature and other parameters related to the cylinder temperature, the abnormity probability reflecting the cylinder temperature can be generated, and thus accurate detection and analysis of the abnormal conditions of the cylinder temperature are realized to facilitate timely early warning and ensure the safe operation of the generator set.

Description

technical field [0001] The invention relates to the technical field of temperature measurement of generator sets, in particular to a method and system for detecting abnormal temperature of a cylinder of a nuclear power plant emergency diesel generator set. Background technique [0002] As the last barrier of the nuclear power supply system, nuclear power emergency diesel units are of great significance to ensure their safety and reliability. For emergency diesel units in nuclear power plants, various signal types of diesel generators are quasi-periodic non-stationary signals, which makes diesel generators have the characteristics of complex fault mechanism, difficulty in collecting and processing various signals, and difficulty in extracting fault characteristics. [0003] Based on the parameter data of emergency diesel engines in nuclear power plants, the cylinder temperature fault is the one with the highest proportion and the greatest impact among many typical faults. Cyl...
