Abstract: A test system for mine reactive power compensation device is designed. Firstly, the working principle of reactive power compensation device is introduced, and then, starting from the voltage level of mine reactive power compensation device, the design schemes for mine high-voltage （3.3 kV, 6 kV, 10 kV） and mine low-voltage （400 V, 660 V, 1 140 V） reactive power compensation device test systems are presented, and the system output parameters for the corresponding voltage levels are listed. Finally, the control strategy and test loading scheme are given.
