Abstract:Control of complex power electronic equipment with high-power usually relies on the real-time simulation to accelerate its development. However, current commercial real-time systems are all monopolized by foreign companies with a lot of drawbacks, such as high cost, poor openness, limited capacity and I/O ports. This paper proposes a real-time simulation system based on multi-field programmable gate array (FPGA). The system uses multi-FPGA as the core parallel computing unit to effectively improve the simulation computing ability and shorten the simulation step. The requirements of data transmission rate between interface cards are analyzed, and an enhanced serial peripheral interface (SPI) communication mode is proposed. Based on this architecture, a real-time simulation platform is developed, and the hardware description language is used to build a 10 kV 12 cascaded H-bridge static synchronous compensator (STATCOM) model for real-time simulation verification. The experimental results show that the real-time simulation step can reach 2 μs while the simulation error between the real-time system and the MATLAB/Simulink waveforms is within 0.5%. © 2017 Automation of Electric Power Systems Press.
