Abstract

The invention discloses a high-voltage circuit breaker fault diagnosis method based on ICA‑LVQ, which is specifically implemented according to the following steps: Step 1: select typical data samples, and divide them into training sets and test sets according to the ratio of 3:1; The input eigenvector of the training sample obtained in step 1 is subjected to dimensionality reduction processing using the LDA algorithm to obtain a new input eigenvector; step 3: the input eigenvector obtained in step 2 is used as the input to construct the ICA-LVQ neural network, after training Learn to output fault classification results, so as to establish a high-voltage circuit breaker fault diagnosis model based on ICA-LVQ; Step 4: Classify the high-voltage circuit breaker fault diagnosis model obtained in step 3 to the test set samples in step 1, and count the classification Accuracy. The ICA‑LVQ-based high voltage circuit breaker fault diagnosis method of the present invention can accurately realize the high voltage circuit breaker fault diagnosis.

Description

Technical field

[0001] The invention belongs to the technical field of high-voltage circuit breaker fault online monitoring, and specifically relates to an ICA-LVQ-based high-voltage circuit breaker fault diagnosis method.Background technique

[0002] Circuit breakers are important equipment in power systems. The reliability of the performance of the circuit breaker is directly related to the reliable operation of the power system, and the reliability of the circuit breaker largely depends on the reliability of its operating mechanism, among which the opening and closing coil is the key component of the operating mechanism. The closing and opening coil current can provide a wealth of information for mechanical fault diagnosis of high-voltage circuit breakers; therefore, fault diagnosis can be performed by extracting the opening and closing coil current signal.

[0003] There are many existing fault detection methods for high-voltage circuit breakers, which involve various artificial intellige...
