The invention belongs to the field of power electronic valve assembly tests, and particularly relates to a switching test method and device for a capacitor strong compensation device. The device is provided with a capacitor module comprising a plurality of capacitors and leading-out connectors corresponding to different capacitors respectively, so that the device can be connected with a capacitor strong compensation device through the leading-out connectors when a test loop is configured, capacitance values connected with the capacitor strong compensation device in parallel are flexibly selected, and different transformer substation filter capacitor working conditions are simulated; moreover, the flexibility of simulating the damping and voltage working conditions of the transformer substation is improved through the damping resistor module and the voltage regulator which are combined in series and parallel at the same time, the same test loop can be adopted to simulate the working environment of the capacito
