Abstract

This paper proposes a detailed switching model for the medium voltage cascaded H-bridge multi level inverter drive and induction motor system using fuzzy logic controller which is suitable for power system dynamic studies. The model includes the aggregated effect of an MVD, an induction motor, and their control system, and thus, it can accurately represent the dynamic responses of the motor drive system under Disturbances. Voltage and frequency both are depended on system modelling. The efficiency of the model is varied by a case study. A sensitivity study is conducted to evaluate the impact of the model parameter variation on dynamic response characteristics. The developed detailed switching model using fuzzy logic controller can be readily inserted in the large-scale power system simulation software for power system dynamic studies.
