Simulation and implementation of new energy grid-connected power line communication system based on FPGA

Aiming at the phenomenon of large amount of data loss in the transmission process of a large number of electronic equipment control signals and data information in the complex environment of new energy grid connection, this paper studies the phenomenon of data loss in the transmission process of new energy grid-connected power line communication system, so as to ensure the coordination and cooperation between new energy power generation equipment and traditional power grid, and realize the detection and management of new energy power generation equipment. The research analyzes the characteristics of the signal in the propagation process of the new energy grid-connected power channel from the reality, and discusses the basic principles of digital signal modulation and demodulation. In this paper, a new energy grid-connected power line communication system is designed and simulated. The changes of signal-to-noise ratio (SNR) and bit error rate (BER)of new energy grid-connected power line channel under different modulation and demodulation of Amplitude Shift Keying (ASK) and Frequency-Shift Keying (FSK) are compared and analyzed. The research shows that FSK is more suitable for new energy grid-connected power line communication system from the perspective of anti-interference and anti-fading. The feasibility of digital signal modulation and demodulation under the new energy grid-connected power channel is verified. The hardware experimental platform is built by Field Programmable Gate Array (FPGA) programming to verify the effectiveness of the simulation, which provides a reference for the new energy grid-connected power line communication system to solve the phenomenon of large data loss during transmission.
