Microprocessor and PI controller based three phase CHBMLI based DSTATCOM for THD mitigation using hybrid control techniques

摘要

Nowadays, in power electronic devices the power quality associated problems are more preoccupied. Different methods of power devices are needed for compensating PQ disturbances. For increasing the PQ one of the power electronic devices used is Distributed STATCOM. The performance of DSTATCOM must be improved by reducing the PQ disturbances. For increasing the behaviour of DSTATCOM and PQ compensation a hybrid controller is developed in this paper. The Radial Basis Function Neural Network method is utilized by deduce the source current for compensation of DSTATCOM and decreasing PQ issues. By using DSTATCOM the harmonic disturbances are decreased. The developed hybrid controller method is utilized to make constant DC voltage in the DC link capacitor of the developed MLI. Consequently, developed method uses Harmonic analysis for estimating the THD values. The proposed technique is developed using matlab simulation. The new developed technique is appraised and differentiated with PI, fuzzy logic, microprocessor and ANN controllers. (C) 2020 Elsevier B.V. All rights reserved.
