Emulador Eletrônico de um Sistema de Geração Eólica Baseado no GSIP Interligado à Rede Elétrica Trifásica

Abstract

This work presents an electronic emulator of a wind generation system (EE-WGS) based on the wind turbine mathematical models (WTMM) virtually composed of the association of a wind turbine and a permanent magnet synchronous generator. Control references, proportional to the electrical power generated by the MMA, are calculated in a reference generation system (RGS) and used to control the input stage of the back-to-back converter composed of an isolated controlled rectifier and an inverter voltage, both connected to the power grid and sharing the same DC bus. The controlled rectifier drains sinusoidal currents from the utility grid, whose amplitudes are proportional to the power defined by the RGS. The voltage source inverter, controlled in current, controls the voltage of the DC-bus, in addition to injecting sinusoidal currents into the grid. In the RGS, the maximum power point tracking is also carried out to optimize the performance of the virtual eolic system. Additionally, in the d-q synchronous reference, the transfer functions of the power converters are presented, as well as the DC-link voltage control. Simulation and experimental results are presented to validate the proposed EE-WGS, seeking to demonstrate and evaluate their static and dynamic behaviors.
