| Resumo: | This work presents the study and development of an electronic eolic emulator (EEE), which is implemented using the mathematical models of a wind turbine (WT) and a permanent magnet synchronous generator (PMSG). Considerind a specific wind speed the interaction between the mentioned models is able to generate the voltage references that will be synthesized by a three-phase inverter, emulating a wind turbine. The proposed EEE presents advantages, in relation to the acquisition of a commercial wind turbine, the low cost and the emulation versatility of different models of commercial wind turbines. Since the energy required for the operation of the eolic emulator comes from the grid, a three-phase controlled rectifier is used in the input stage of the emulator to control the voltage of the inverter DC-bus, as well as drain sinusoidal current form the grid so that high power factor is achieved. Besides the mathematical modeling of the DC-bus voltage plant, the mathematical models of the three-phase inverter and the three-phase controlled rectifier are presented in this work, where they are obtained in the synchronous reference frame(dq-axes). Consequently, all the controllers of the power converters are also implemented in rotating frame dq. Based on the power converters and the DC-bus voltage models, the projects for obtaining the gains of the voltage and current controllers are perfomed. In order to validate the study, as well as to evaluate the static and dynamic performances of the EEE, simulation and experimental results are presented considering the system submitted to different operating conditions. |
