A set value checking method for relay protection of ship integrated power system
A relay protection setting verification method based on big data is proposed for the integrated power system of ships.Firstly,in response to the massive dynamic data generated by the integrated power system of ships,the SOM clus-tering algorithm is used to mine the operational data of the power system.Then,the SOM clustering algorithm based on par-tial distortion is adopted to improve clustering efficiency.After calculating the connection weight vector,the current minim-um Euclidean distance and the Euclidean distance of the vector are determined,and then the decision is made whether to con-tinue clustering;Finally,based on the operating data of the power system,a fault calculation method based on Word equival-ence is adopted to obtain the fault calculation results.Referring to the fixed value verification rules,the relay protection fixed value verification is completed.The experiment shows that this method can accurately classify the current and voltage data of the ship's integrated power system through SOM clustering processing,and can accurately obtain the calibration results of re-lay protection lines,which can provide support for improving the safety of the ship's integrated power system.
