Abstract
The disclosure discloses a virtual impedance comprehensive control method for an inductive power filtering (IPF) system. According to the disclosure, harmonic damping control at grid side and zero impedance control of filters are organically combined according to a technical problem which is unsolved and process difficulty in equipment manufacturing in an existing filtering method, so that the problem of performance reduction of passive filtering equipment caused by a change in an impedance parameter of a power grid system is solved on one hand, optimization control over a quality factor of the passive filtering equipment may be implemented to reduce dependence on an equipment production process level on the other hand, a quality factor of the single-tuned filters may meet a design requirement, and an overall filtering characteristic is further improved.
