description The invention relates to the technical field of dynamic reactive compensation, and discloses an STATCOM control method and device, and the method comprises the steps: carrying out the reactive power control or AC voltage control of an STATCOM, and obtaining the amplitude of an instruction voltage; performing power synchronous control on the STATCOM to obtain the frequency of the instruction voltage; performing virtual potential control on the STATCOM based on the amplitude and frequency of the instruction voltage to obtain a current reference value; and obtaining a switching signal of the STATCOM by using the current reference value and a preset modulation method. According to the invention, a power synchronous control link is added into the control of the STATCOM, so that the STATCOM has a current within an allowable range of a device which is rapidly output by a synchronous phase modifier when the system voltage is suddenly changed, and meanwhile, the STATCOM can rapidly respond to a reactive power instruct
