Abstract

Switched Reluctance Generator (SRG) possesses the advantages of simple structure, low cost, high reliability and high fault tolerance. For promoting the intelligence of SRG based distributed power network, reliable communication is the key to achieve system monitoring, remote control, fault protection, etc. Power and Signal Composite Modulation (PSCM) methods are newly proposed to realize power-line communication (PLC) for SRG-based distributed microgrid. Two signal modulation methods are implemented on the basis of Current Chopping Control (CCC) by modulating either chopping references or chopping threshold of phase currents, so as to obtain voltage ripples with different frequencies to carry signals. Fast Fourier Transform (FFT) method is adopted for demodulating the transmitted data on receiving side. The proposed PSCM strategies are experimentally tested for SRG system with phase failure in distributed microgrid.
