Design and Implementation of Power Harmonic Monitoring System based on Robust Kalman Filtering

摘要

The inverters consisted of Power Electronic Devices are widely used in dredger, which makes Dredger Power System lots of Upper Harmonic. In order to achieve precise harmonic monitoring of cutter suction dredger power system, the paper proposes a power harmonic monitoring system based on Robust Kalman Filtering (RKF). In the simulation experiments, it showed that the Robust Kalman Filtering (RKF) is superior to the Kalman Filtering (KF) because the optimal estimate value is almost in agreement with the ideal value after adding the RKF. It gives experimental set-up and algorithm principle of RKF, and explains the correctness and feasibility of Power Harmonic Monitoring System based on Robust Kalman Filtering in the theory.
