Problems solved by technology

At the same time, since the power station is a typical multi-mode system, the parameters under different working conditions have different statistical characteristics, and it is difficult for a single PCA monitoring model to learn such statistical characteristics, so it cannot obtain better monitoring results

Abstract

The invention discloses a power station equipment fault monitoring model generation method, system and device, and the method comprises the steps: presetting the maximum capacity of an initial training sample set, and carrying out the standardization processing of a large amount of historical normal data stored in a database based on the maximum capacity, and obtaining a training sample set containing training data; determining an optimal cluster number by calculating and comparing Calinski-Harabasz score values under training data under different clusters, taking the determined optimal cluster number as a cluster number of a K-means algorithm, and performing algorithm training on the training data to determine a clustering center set of the data; and taking the determined clustering center set as an initial clustering center of an FCM algorithm, performing algorithm training on training data to determine a cluster membership degree of the data, establishing an FCM model, classifying the training data according to the maximum membership degree, establishing corresponding PCA models according to different categories, and completing a training process.

Description

technical field [0001] The invention relates to the technical field of power station monitoring, in particular to a method, system and device for generating a fault monitoring model of power station equipment. Background technique [0002] In the prior art, fault detection (Fault Detection) is to use when a fault occurs in the system, to find and confirm it in time, and to give a corresponding display or alarm. Early detection of failures can provide important warnings of impending problems, allowing appropriate action to be taken to avoid serious incidents. PCA (Principle Component Analysis) fault monitoring method belongs to the fault monitoring method in the field of statistical learning. It has the characteristics of high efficiency, convenient calculation and does not depend on fault variables, and has been widely used in recent years. [0003] Fault monitoring of power station equipment is an important link in the safe and economic operation of power stations. Contin...
