Abstract

This paper presents the analyzed results of a permanent-magnet synchronous generator-based microturbine generator (MTG) system connected to a distribution system through an AC-to-DC converter and a DC-to-AC inverter. The employed mathematical model based on a dq-axis reference frame is derived to establish the complete dynamic equations of the studied MTG system for simulating the characteristics of the MTG under various operating conditions. A damping controller is designed for the DC-to-AC inverter using modal control theory to render adequate damping characteristics to the studied MTG under various disturbance conditions. Steady-state performance and dynamic simulations of the studied MTG under different operating conditions and various disturbance conditions are carried out, respectively. It can be concluded from the simulation results that the designed damping controller of the DC-to-AC inverter can provide adequate and effective damping characteristics to the studied grid-connected MTG system under disturbance conditions.
