Abstract

A performance monitoring method for thermal power equipment based on big data analysis mining mainly comprises the following steps: step 1, implementing correlation analysis and principal component analysis on the health running data of a power station; and step 2, obtaining principal component variables of equipment by using the correlation of the equipment data and performing principal component analysis, establishing a three-dimensional cluster for normal operating conditions by performing density-based clustering analysis, and monitoring the performance of the equipment by using the cluster. Compared with a traditional performance monitoring method for the thermal power equipment, the performance monitoring method using the big data can fully use a large number of the thermal power plant operating data, and thus the real-time performance of the equipment can be reflected, and the monitoring accuracy can be increased.

Description

technical field [0001] The invention relates to a thermal power equipment performance monitoring technology, a thermal power equipment performance monitoring method based on big data analysis and mining, and belongs to the field of power plant performance monitoring and fault diagnosis. Background technique [0002] For a relatively long period of time, thermal power generation still occupies a dominant position in my country's electricity production. A power plant is a complex series-parallel system composed of multiple interrelated subsystems, and its safe and reliable operation is particularly important. Performance monitoring technology is widely used in power plants to ensure their safe operation. In terms of performance monitoring of thermal power units, the current mainstream monitoring methods are mainly platforms based on physical mechanism modeling, such as EfficencyMap, Ebsilon, Optimax, Turabs and other platforms. The utilization of these data and the mining of...
