Abstract

In this paper an approach of synchronous breaking technology of vacuum circuit breaker is presented. In order to predict the zero of a short circuit current, the recurrence formula is built according to the general expression of short circuit current, and it is simple without complex calculation and easy to come true by hardware and software. The simulation results for the actual measurement short circuit current show good predicting ability and high precision. Furthermore, support vector machine (SVM) is using for compensating the offset of the breaking time from the driving mechanism, and the model is built by minimum mean-square value SVM.
