Modelling and simulation of microturbine for a distribution system network with hybrid filter

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 necessity of reducing the harmonics injected by the microturbine generation system into the grid is solved by introducing a hybrid filter. The simulations of the microturbine generation system for the filter is done and the waveforms, THD and harmonic spectrum of the grid current with the use of the hybrid filter in the system are studied. The study shows that the hybrid filter provides harmonic reduction in the grid current.
