FPGA Implementation of Real-Time Simulation Model of Wind Turbine Connected to Grid

According to the real-time simulation requirements of permanent magnet synchronous wind turbine grid connection, a real-time simulation method of circuit electromagnetic transient based on ARM + FPGA platform is proposed, the judgment method of switching element state is introduced, and the corresponding real-time simulator is developed. The basic architecture of real-time simulator based on ARM + FPGA is given, and the pipe line method is introduced into the matrix multiplication operation of FPGA. The simulation of permanent magnet synchronous wind turbine grid connection model is carried out based on this platform, the voltage and current waveforms in steady state and fault state are verified. The results show that the simulation effect of the real-time simulator is highly consistent with the results of the offline simulation software.
