摘要

本文介绍了一种克服智能电网中电力线通信(PLC)配电变压器信号过度衰减的新方案。该解决方案避免了传统的硬件旁路,也不需要像OFDM这样复杂的调制方案。探讨了在千赫范围内发生在变压器绕组中的共振以传输通信信号。测量了BPSK信号在配电变压器中的误码率,并对其进行了仿真。实测数据和仿真数据表明,该方案能够成功地将信号通过电网变压器进行传输。

Feasibility of data communication through distribution transformers for Smart Grid applications
This work introduces a novel solution to overcome excessive signal attenuation in distribution transformers for power line communication (PLC) in Smart Grids. The solution avoids classical hardware bypass and does not require sophisticated modulation schemes like OFDM. It explores the resonance that occurs in transformer windings at kHz range to transmit the communication signal. The Bit Error rate (BER) of a BPSK signal propagating through a distribution transformer was measured and an accurate model was simulated. The measured and simulated data presented show that the proposed solution has successfully propagated the signal through the grid transformer.
