Abstract
An intelligent circuit breaker with synchronous closing function based on DSP is presented in this paper. By which, the filtering algorithm based on Fourier algorithm is adopted in order to estimate the optimal reclosing angle so as to weaken the instantaneous current during reclosing circuit Based on the discussion of the digital signal processing technology, the hardware circuit has been set up and the software has been programmed. And the simulation results show a good agreement with the predictions.
