A two-channel data and power synchronous transmission method for SRG-integrated power networks through piecewise composite modulation
Reliable communication is key to achieving remote control, status monitoring, and early fault detection in SRG-integrated power networks. This paper proposes a novel piecewise composite modulation method to simultaneously modulate data and power during the excitation and power generation stages in each phase of an SRG system. By adopting a frequency-shift keying modulation strategy, two-channel data can be modulated and injected into the bus voltage as voltage ripples, allowing for more efficient use of the bus voltage frequency band. Welch's algorithm-based power spectrum method is innovatively employed to demodulate the transmitted data on the SRG's output bus. Experimental results confirm the feasibility of the proposed data and power synchronous transmission (DPST) strategy, which shows significant potential in SRG-integrated power networks.
