In order to ensure the safe and stable operation of the large power grid with high proportion of renewable energy access, the automatic voltage control (AVC) system of the new energy power station is very important. The control strategy of the AVC and the response characteristics of the voltage and reactive power regulating equipment will affect the AVC regulation effect directly. However, the pure digital simulation software cannot simulate its actual response characteristic. This paper established a hardware in loop (HIL) testing platform based on RT-LAB real-time simulation system. The real AVC controller and the real static var generator (SVG) controller hardware are connected to RT-LAB testing platform via I/O physical interface and MODBUS communication, and the HIL coordinated simulation testing scheme is studied based on FPGA of RT-LAB. With established testing platform, the voltage regulating characteristic and reactive power replacement capacity of AVC control strategy is verified.
