基于BP人工神經(jīng)網(wǎng)絡(luò)的絕緣子泄漏電流預(yù)測(cè)
[Abstract]:There is a close relationship between the leakage current of external insulation and the flashover process of insulator, and the relative humidity is one of the key factors affecting the generation and development of leakage current. Firstly, two kinds of commonly used suspended insulators were tested by artificial pollution test. The leakage current waveform of two kinds of commonly used insulators under different relative humidity was recorded and analyzed by the leakage current measurement system. The corresponding relationship between the maximum leakage current under different humidity is established by using BP artificial neural network, and the Levenberg-Marquardt fast learning algorithm is selected to train the established BP neural network. The verification of partial test data and the curve of leakage current with relative humidity obtained by different methods show that, Using the neural network to establish the relationship between the maximum leakage current in different surface damp states is accurate and effective.
