Method and device for testing excitation system of phase modifier

The invention discloses a method and a device for testing an excitation system of a phase modifier. The method comprises the following steps: based on a target scene for testing the phase modifier excitation system, determining a simulation power grid model connected to the phase modifier excitation system and target scene disturbance data for disturbing the phase modifier excitation system; determining simulation disturbance data of the simulation power grid model and fault disturbance data of the simulation predetermined fault; determining multiple sections of target disturbance data according to the target scene disturbance data, the simulation disturbance data and the fault disturbance data; and testing the phase modifier excitation system according to the simulation power grid model and the multi-section target disturbance data to obtain a test result of the phase modifier excitation system in the target scene. According to the invention, the technical problem of incomplete test caused by the fact that t
