Investigation of Electromechanical Characteristics of a Three-Phase Linear Generator

Abstract

The motion of sea waves can be converted into electrical energy using a three-phase linear generator. This paper investigates the electromechanical characteristics of two types of the three-phase linear generator, namely TPLG-6 and TPLG-18. The electromechanical characteristics such as power, efficiency, torque, d-q axis synchronous inductance, saliency ratio and current are investigated. MATLAB Simulink is used for the simulation. In this study, the d-q synchronous inductance is calculated to investigate the effects of d-q synchronous inductance on the permanent magnet. The Maximum Torque Per Ampere (MTPA) is plotted to determine the torque required to generate the maximum d-q current. The saliency ratio will also be investigated by comparing the d-q synchronous inductance for TPLG-6 and TPLG-18.
