Analysis on transmission characteristics of broadband power line carrier and power frequency integrated communication for new energy microgrid

For the new energy microgrid oriented communication technologies, the broadband power line communication (BPLC) is able to achieve high speed, but there still exists anti-jamming and the anti-attenuation problems. The two-way Automatic Communication System (TWACS) has better performance on anti-jamming and the anti-attenuation ability. In this article, analysis is conducted on the communication principle of both BPLC and TWACS. The transmission model is proposed for integrated communication of BPLC and TWACS based on Wegener distribution. The transmission characteristic model of BPLC and TWACS is evaluated by simulation. The channel state is also determined by the noise with Wegener distribution, which can be used for the carrier frequency selection to better the performance of BPLC.
