“…The wind turbine generates AC power at changing frequencies (VF), which then must be converted into CF AC voltage for distribution and integration into the public electrical network. In that respect, the work by Malinowski, Milczarek, Kot, Goryca, and Szuster (2015) was very useful in choosing proper technologies and power electronics systems theory and practice.…”

A proposed novel DC-Link VSCF AC-DC-AC electrical power system converter for Embraer 190/195 transport category airplane is presented. The proposed converter could replace the existing conventional system based on the CSCF IDGs. Several contemporary production airplanes already have VSCF as a major or backup source of electrical power. Problems existed with the older VSCF systems in the past; however, the switched power electronics and digital controllers have matured and can be now, in our opinion, safely integrated and replace existing constant-speed hydraulic transmissions powering CSCF AC generators. IGBT power transistors for medium-level power conversion and relatively fast efficient switching are used. Electric power generation, conversion, distribution, protection, and load management utilizing VSCF offers flexibility, redundancy, and reliability not available with a conventional CSCF IDG systems. The proposed DC-Link VSCF system for E190/195 delivers several levels of 3-w AC and DC power, namely 330/270/28 VDC and 200/ 115/26 VAC utilizing 12-pulse rectifiers, Buck converters, and 3-w 12-step inverters with D-Y, Y-Y, and Y-D 3-w transformers. Conventional bipolar double-edge carrier-based pulse-width-modulation using three reference AC phase signals and up to 100 kHz triangular carriers are used in a manner to remove all even and many odd super-harmonics. Passive low-pass filters are used to remove higher harmonics. The RL AC loads are active in connection with the synchronous and induction AC motors and also include passive AC loads. The overall power factor exceeded 85%. Total harmonic distortions for voltages and currents are below 5%, thus satisfying the MIL-STD-704F and the IEEE Std. 519 power-quality standards, while avoiding the need for active filters. Several PI and PID controllers that regulate synchronous generator DC excitation and inverter banks were designed and tuned using the continuous-cycle tuning method to offer required performance and stability of the feedback loop. Mathworks's Simulink TM software was used for simulation of electrical components and circuits. Several critical scenarios of aircraft operations were simulated, such as go-around, to evaluate the transient behavior of the VSCF system.

“…Já as turbinas eólicas de pequeno porte (TEPP) são opções ainda em desenvolvimento científico e tecnológico, e que ainda estão num processo de consolidação no mercado de energia renovável. Contudo, este processo está ocorrendo num ritmo acelerado, pois dados mostram que este segmento cresce 20% ao ano [1], [2], principalmente em aplicações residenciais, comerciais e em fazendas. Os EUA foi o país que apresentou maior crescimento, em torno de 35% ao ano, tornando-se um mercado considerável e uma vitrine desta tendência para os outros países com características geográficas semelhantes.…”

“…Os EUA foi o país que apresentou maior crescimento, em torno de 35% ao ano, tornando-se um mercado considerável e uma vitrine desta tendência para os outros países com características geográficas semelhantes. A expectativa é que esse crescimento de TEPPs continue nos próximos anos, com previsão de 350 MW em novas instalações em 2016 [1], [2]. Considerando o crescimento de 20% ao ano, em 2020 serão aproximadamente 750 MW em novas instalações, sendo que a potência total instalada chegará a valores próximos de 3 GW.…”

Resumo -Este artigo apresenta um sistema para conexão de turbinas eólicas de pequeno porte à rede elétrica, o qual controla a corrente injetada na rede e rastreia a máxima potência elétrica do gerador. O sistema proposto é composto por uma ponte retificadora trifásica do tipo Ponte de Graetz, um conversor CC-CC tipo Forward, que proporciona isolação, controle e ganho, e um inversor Full-Bridge, que comuta em baixa frequência, com intuito de inverter a corrente do conversor CC-CC e injetá-la na rede elétrica. A solução proposta é baseada em simplicidade, baixo custo, volume reduzido e robustez. O texto apresenta a análise da topologia, princípio de operação, modelos dinâmicos, estrutura de controle e resultados experimentais para um aerogerador de 1 kW conectado à rede elétrica (220 V/60 Hz). A SYSTEM FOR CONNECTION TO THE GRID OF SMALL WIND TURBINESAbstract -This paper proposes a system to connect a small wind turbine into the electric grid, which controls the current injected into the mains and tracks the maximum power of the generator. The proposed system is based on a three-phase diode bridge rectifier, a DC-DC Forward converter that provides electrical isolation, gain and control, and a Full-Bridge inverter that is switched at low frequency to invert the current from the DC-DC power converter and inject it into the electrical grid. The solution is based on simplicity, low cost, low size and the potential to be robust. The analysis of the topological states, principle of operation, dynamic models, controller structures, simulation results and experimental results for a 1 kW system connected to the mains (220 V/60 Hz) are presented herein.
