Experimental evaluation of matrix converter for wind energy conversion system under various abnormal conditions

Abstract

This paper presents the experimental evaluation of reversed indirect matrix converter (MC) interfaced wind energy conversion system (WECS), where space vector pulse width modulation together with adaptive fuzzy logic control is effectively used to enhance the performance of system under various abnormal conditions like abrupt change in wind speed, disconnection from grid, misfire in the converter, sudden out of one phase, change in load etc. The proposed adaptive control system is realized using dSPACE DS1104 board. Selective experimental results are presented using a laboratory 1.2 kW prototype of WECS to demonstrate the resulting improvements of the developed system under abnormal conditions.
