Wireless short-range device for wind generators

Abstract

Cooperation of small generation units within distributed generation system or micro-grid require solving many communication, control and data transmission problems. A wind energy conversion system (WECS) with squirrel cage induction generator (SCIG) and a full-scale power converter is considered in present paper. Application of wireless communication in WECS is discussed in the paper. Some experimental results are presented.

Performance of a Direct Power Control System Using Coded Wireless OFDM Power Reference Transmissions for Switched Reluctance Aerogenerators in a Smart Grid Scenario

“…It is worth noting that there are researches in the scientific literature referencing the application of wireless technology in multilayered architecture for end-to-end connectivity at industrial systems [47], or for monitoring wind energy systems based on sensor networks [48]- [50]; however, there has not been any deep research presented about the use of wireless technology for control applications in these systems, making it difficult to estimate the real impact of its use or its advantages and difficulties. Additionally, implementation and studies of communication systems for wireless monitoring and control applications in wind plants referenced to a remote system are presented in the papers [51], [52], demonstrating its potential applicability in the close future.…”

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 trend is explained by their increasing reliability, reduced cost, easy maintenance, high speed, and flexibility of connection between different devices [22][23][24][25]. In the literature, it is possible to find several studies about wireless systems in the control of renewable energy systems [10,[26][27][28][29][30][31]. Despite the inherent difficulties of transmitting signals through wireless channels such as noise, interferences, and multipath fading, the use of wireless systems has become increasingly attractive, especially with the materialization of the SG [32].…”

Wireless coding deadbeat power control for doubly-fed induction aerogenerators in smart grid applications

“…A codificação LDPC foi recentemente acrescentada ao padrão IEEE 802.16e, mais conhecido como WiMAX (Worldwide Interoperability for Microwave Access) para aplicações móveis (IEEE, 2004). E importante ressaltar que existem alguns trabalhos na literatura científica referentesà aplicação da tecnologia sem fio no monitoramento de geradores eólicos baseados em redes de sensores (Adamowicz et al, 2010a;Adamowicz et al, 2010b), entretanto não existem estudos mais profundos relacionados a utilização da tecnologia sem fio para aplicações de controle nestes sistemas supracitados. Adicionalmente, nos trabalhos de Li et al (2009), Anaya-Lara et al (2006) e Wanzhi et al (2009 são apresentados estudos e implementações de sistemas de comunicação sem fio para aplicações de controle e monitoramento em plantas eólicas referenciadas a uma central remota, demonstrando seu potencial de aplicabilidade em um futuro próximo.…”
