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.

分布式微电网中基于CCC的SRG的功率和信号复合调制新策略

开关磁阻发电机（SRG）具有结构简单，成本低，可靠性高，容错能力强的优点。为了提高基于SRG的分布式电网的智能性，可靠的通信是实现系统监控，远程控制，故障保护等的关键。新提出了电源和信号复合调制（PSCM）方法来实现电力线通信（PLC）用于基于SRG的分布式微电网。在电流斩波控制（CCC）的基础上，通过对斩波基准或相位电流的斩波阈值进行调制，可以实现两种信号调制方式，从而获得不同频率的电压纹波来承载信号。采用快速傅里叶变换（FFT）方法在接收侧对发送的数据进行解调。
