【 摘 要 】

To develop and design the power electric hardware, the hardware-in-the-loop simulation system suitable for power electronics is carried out. An architecture of hardware-in-the-loop simulation system in power electronic based on multi field-programmable gate array (FPGA) is presented. The functional modules of the hardware-in-the-loop simulation system are independent, and different functional boards are formed to facilitate the system expansion. The full hardware FPGA architecture is adopted, and multi-chip FPGA is used as the parallel core operation unit. Therefore, the system simulation capacity is effectively increased. At the same time, the simulation step is shortened, and the simulation precision of the system is ensured. In addition, the hardware-in-the-loop simulation platform based on multi FPGA is built. The external controller and the hardware-in-the-loop simulation platform are connected to realize the closed-loop simulation control of the hardware in the 10k V STATCOM. The experimental results show that the system can take a long and stable hardware-in-the-loop simulation for the power electronic devices with ideal condition and non-ideal condition. The controller can be directly applied to the actual platform by the hardware-in-the-loop-simulation.
