Application of Fault Diagnosis of High Voltage Inverter with BP Neural Network

摘要

A fault diagnosis technology of frequency converter based on BP neural network is discussed in this paper. Through the analysis of the operation of high-voltage inverter in the special industry situation, the BP neural network topology structure is established. With optimizing the network parameters and extracting, analyzing and processing the fault information, the high-voltage inverter error can also be diagnosed precisely. Furthermore, by the practical application of the coal industry, the correctness of the theoretical analysis is verified, which has a great significance in the promotion of the industry.
