Nowadays, the massive implementation of new energy components in power system has been proved to be effective on the alleviation of energy crisis and environment pollution. However, the connection of new energy components to the grid may cause severe fluctuation to the system without pre- test. Thus, the requirement for the real-time simulation of new energy components becomes inevitable. Traditional field-programmable gate array (FPGA) based real-time simulation platform is developed through hardware description language (HDL) with considerable time spent on the hardware implementation of component model, which is not capable to the fast development of new energy components. To address this problem, in this paper, we adopt high-level synthesis (HLS) technology to accelerate the hardware implementation of mathematical discrete model for new energy components such as doubly-fed induction generator (DFIG). Directives like loop-unrolling, pipeline and so on, are adopted for the simulation performance improvement. The simulation time step achieves 2µs adopting double-precision float-point on Xilinx XC7V690T FPGA. Comparison between real-time and off-line simulation reveals that our efforts decent results while reducing the simulation development cycle significantly.
