Development of a Wind Turbine Emulator Based on Dynamic Model of a Permanent Magnet Synchronous Generator

Abstract

This work presents the development of an electronic wind emulator (EWEm), which involves the dynamic models of the wind turbine, the permanent magnet synchronous generator and the mechanical coupling turbine-generator. These models are used to generate the EWEm voltage references, which are synthesized by a three-phase three-wire voltage source inverter, so that a real wind turbine can be emulated at different wind speeds. As advantages, the proposed EWEm presents low cost of implementation and versatility in the emulation of different models of Artigo submetido em 25/04/2019. Primeira revisão em 13/06/2019.

A three-phase controlled rectifier is used in the input stage of the EWEm to control the DC-bus voltage of the inverter, as well as drain sinusoidal currents from the grid, so that an effective power factor correction is achieved. Both mathematical models of the inverter and the input rectifier are represented in the synchronous reference frame dq. In order to validate the study, as well as to evaluate the static and dynamic performances of the proposed EWEm, experimental results are presented considering the system subjected to different types of load and wind profiles.
