State Perception Method of Intelligent Substation Secondary System Based on FCE and DCNN
Aiming at second equipment lacks comprehensive and effective state detection and simple and reliable evaluation method, a state perception method of intelligent substation secondary system based on fuzzy comprehensive evaluation (FCE) and deep convolutional neural network (DCNN) is proposed. Firstly, combining with the factors of auxiliary equipment state evaluation, the FCE method is adopted to evaluate the influence degree of each secondary equipment. Secondly, DCNN was used to learn the regional and edge features respectively, and the significance and non-significance confidence of the detected region was obtained. Finally, combined with the influence degree of each secondary equipment and the significant and non-significant confidence level, the state of the secondary equipment in intelligent substation is evaluated. The experiment results indicate that the proposed method can effectively solve the deficiency of the corresponding equipment status detection and evaluation method of intelligent substation.
