Power Hardware-in-the-loop Simulation of a Gas Engine Cogeneration System for Developing a Power Converter System

Abstract

This research focuses on the development scheme of a power converter in a gas engine cogeneration system using a power hardware-in-the-loop simulation. A matrix converter is adopted to substitute a conventional ac/dc/ac converter and transfers three phase electricity to single phase electricity directly. To inevstigate the interaction between gas engine-generator unit and the proposed matrix converter, a power hardware-in-the-loop simulation is carried out, in which a piece of real matrix converter is installed in the simulation loop and interfaces with the numerical model of gas engine-generator unit. Numerical models of gas engine and generator are presented and verified by experiment. The configuration of the power hardware-in-the-loop simulation is described and results are also presented, through which the practical application of matrix converter is well demonstrated.
