Mitigation of the voltage fluctuations using an efficient disturbance extraction technique

摘要

This paper introduces an efficient technique for extracting the disturbance signal of the voltage flicker. The proposed technique depends on the supervised state estimation that is controlled by the Widrow-Hoff delta rule. The extracted disturbance signal is employed for mitigating the cyclic voltage flicker by using series and parallel mitigating devices. The speed and accuracy of the proposed technique are verified by simulation results with EMTDC/PSC AD. In addition, experimental results are presented to prove the validity of the proposed algorithm.
