Modelling and simulation of microturbine for a distribution system network

Abstract

Distributed generation systems have become the new focus of the world and microturbine generation system is one of the systems. The connection of a microturbine generator to a distribution system requires the use of an AC/DC/AC power converter which in turn creates a harmonic problem to the distribution system. A modelling of a microturbine generation system on PSCAD is presented and the harmonic impact of the microturbine generation system on the distribution system is investigated. The simulations of the microturbine generation system for the distribution system network is done and the waveforms, THD and harmonic spectrum of the grid current in the system are studied. The study shows that the THD harmonic of the grid current (Igrid) for microturbine generation system found to be high, which is 36.43%
