The invention discloses a dynamic
harmonic filtering control method and
system, and relates to the technical field of
electric power, and the method comprises the steps: collecting a
voltage signal and a current
signal of a
power grid in real time; performing
spectral analysis on the collected signals, and extracting
harmonic characteristics; based on the
harmonic characteristics, generating a compensation
signal and optimizing the compensation signal; dynamically adjusting filtering parameters, and injecting an optimized compensation signal into a
power grid through a filter module; uploading a
system operation state in real time, and detecting and marking an abnormal state; according to the invention,
rapid response and efficient suppression of
power grid harmonics can be realized, the adaptability and filtering precision of multi-band
harmonics are significantly improved, and the total
distortion rate of the
harmonics is greatly reduced, so that the quality of
electric energy is optimized. The
system operation efficiency and stability are improved, the anti-interference capability is strong, and the system is suitable for a complex power grid environment; the system can monitor the operation state in real time, automatically give an alarm and mark abnormity, the reliability and safety of power grid operation are improved, and the maintenance cost is reduced.
