Resumo-Este artigo propõe um controlador preditivo baseado em um modelo aplicado no gerador de indução de gaiola de esquilo usando um controle direto de torque. O sistema é composto por um gerador, que é conectado à rede de energia através de um conversor back-to-back. O conversor conectado à rede emprega a técnica de controle preditivo direto de potência. Sendo assim, é possível controlar a potência ativa e reativa que será injetada na rede. O controlador preditivo não necessita de sintonia e possui menor complexidade de implementação. Em ambos os casos, o controlador preditivo seleciona o vetor ótimo a ser aplicado no conversor do gerador ou no conversor da rede elétrica através da minimização de uma função custo, de forma que as referências sejam atendidas. Os resultados experimentais mostrarão o desempenho do controlador preditivo proposto.

“…As turbinas eólicas podem empregar máquinas elétricas síncronas, de indução ou de relutância variável [4]- [6], entre outras. Os geradores eólicos podem ser ligados diretamente à rede ou por meio de conversores eletrônicos de potência [7], que aumentam a eficiência do sistema devido à possibilidade de operar com velocidade variável [8].…”

“…Regarding the use of wind energy, an interesting solution is the use of Doubly Fed Induction Generators (DFIGs) connected to the grid [6][7][8][9]. This type of machine presents some important advantages, such as operation in four quadrants and processing of only 25% to 30% of its nominal power by the converter, while other electrical machines, such as the Switched Reluctance Generator (SRG), Squirrel Cage Induction Generator (SCIG), and Synchronous Generator (SyG) process full power by the converter [10][11][12].…”

Analysis of a Control System for DFIG Wind Generators Based on the Transmission of Power References through a GSM Wireless Network: A Smart Grid Experimental Approach

This work proposes the use of the automatic Short Message Service (SMS) of a Global System for Mobile Communication (GSM) network to transmit the control information to a Doubly Fed Induction Generator (DFIG) of a wind turbine, according to the Smart Grid (SG) concept. In the proposed strategy, the Control Center (CC) can remotely transmit the required power references (active and reactive) to the DFIG controller, in order to manage the power generation of the wind turbine dynamically. The proposed wireless network was developed in a Software Defined Radio (SDR) transceiver connected to an OpenBTS platform. The control information can be directly inserted in the Open Base Transceiver Station (OpenBTS) server (located at the CC) or sent by a wireless device (e.g., mobile phone) connected to the GSM network, and then transmitted to the wireless receiver at the wind turbine. The receiver on the turbine side was developed in a microcontroller board with a GSM card, and the DFIG controller was implemented in a Digital Signal Processor (DSP) board. The results of the tests showed that the DFIG can be satisfactorily controlled according to the power references, considering that they vary at low rates.

An impulsive noise filter applied in wireless control of wind turbines

et al. 2016

View full text Add to dashboard Cite

a b s t r a c tThis paper proposes a novel non-linear filter applied to wireless-transmitted reference signals in a deadbeat control strategy of a doubly-fed induction wind turbines. These signals are likely to be corrupted by spikes intrinsically imposed by the wireless channel. This impulsive noise is traditionally mitigated using classical error-correction schemes, and the proposed filter is an alternative that is simpler and has lower computational cost. The proposed technique, hereby designated as FunctionallyWeighted Moving Average (FWMA) filter, is based on a non-conventional weighting of the signal samples, which is carried out by a rectangular function. The filter realization is as straight as any linear technique. The generator control scheme, which includes the filter, is embedded in a microprocessor locally placed at the generator site, where it acts on the reference signals at the receiving end of the channel. The performance of both the filter and the control system are verified by simulations that include the wind turbine dynamics and the communication channel. The proposed technique is compared with a morphological filter, previously suggested for the same purpose. The results endorse the FWMA filter efficacy to clean out impulsive interferences with minor delays.
