“…O protocolo de cooperação considerado pelo PC-MAC e pelo W/O Corr. foi o PLC-CMAC [11]. Por fim, vale ressaltar que a camada física foi tratada como uma "caixa preta", tendo sido utilizados, nas simulações, apenas valores de BER associados a cada enlace (SR, SD e RD PLC e sem fio), que podem corromper cada bit das sequências binárias (pacotes) transmitidos.…”

“…Caso pelo menos uma dessas cópias seja recebida corretamente pelo nó D, o mesmo envia um acknowledgment (ACK) ao nó S. Caso contrário, o nó D ativa o protocolo de correção de pacotes, que utilizará as duas cópias corrompidas de m, presentes em bf rRX D . Apenas após uma falha do protocolo de correção, o nó D envia um NACK ao nó S, que também é recebido por R. Quando isso ocorre, um processo de retransmissão se inicia, que ocorre de forma cooperativa com o uso do protocolo PLC-CMAC [11]. Depois da retransmissão, o nó D recebe duas cópias do pacote retransmitido, m PR e m WR .…”

“…Nesse contexto, Oliveira et al [11] mostra que protocolos de cooperação, na camada de enlace de sistemas PLC, podem oferecer melhorias no goodput e na confiabilidade da comunicação. Porém, quando técnicas e protocolos preexistentes não são suficientes para assegurar essa confiabilidade, excessos de retransmissões e até mesmo perdas de pacotes de dados podem ocorrer.…”

Resumo-Este artigo introduz um novo protocolo de correção de pacotes que atua na camada de enlace de sistemas híbridos PLC/wireless. O objetivo da presente proposta é a redução da necessidade de retransmissões e até mesmo da perda de pacotes de dados. Por atuar na camada de enlace, a presente proposta é capaz de introduzir melhorias e preservar o legado de camadas físicas padronizadas. Resultados numéricos mostram que, mesmo no pior caso, no qual uma de taxa de erro de bit de 10 −5 é considerada, sistemas de comunicações apresentam perdas de pacotes de 10 −14.78 , quando consideram o uso do protocolo proposto, e de 10 −2.81 quando não o consideram.

“…This solution allows for the identification of users with high accuracy and reliability, without misjudgment or unidentified users, over a long transmission distance. However, a downside of this approach is that carrier signals can be interfered with when common high voltage, common ground, common line trench string, and cross‐transformer coupling are present, affecting the ability of the transformer area identifier to identify line topology [10]. Populating the substation area identification instrument and applying it to establish the membership relationship between users and transformers requires significant manpower and material resources.…”

Communication quality is a key factor affecting the effectiveness of distribution network operation status management. Therefore, it is required that the communication performance of the distribution network management system be good, and the communication signal can directly reflect the communication quality. Therefore, a genetic algorithm (GA) based HPLC communication signal feature extraction method is proposed. The process of constructing reference samples, training recognition models, constructing noise samples, self‐coding denoising processing, and denoising sample recognition has completed the identification of power line channel transmission characteristics. The state feature quantity of the topological line is based on the positioning results of the diagnostic function, and the calculated value of the reflection coefficient calculation model at the head end of the topological line is compared with the measured value. By optimizing the feature quantities containing topological line states through GAs, abnormal feature quantities close to the true state of topological lines are obtained. Experimental analysis shows that this method can correctly identify the position of reactive power compensation in the transmission line, and can also correctly identify the extraction of topological anomaly features. Therefore, the research method is of great significance in improving the safe operation of power systems and extending the service life of topology lines.

“…Reviewing the literature about PLC technologies, measurement [11], [12], characterization [13] and modeling, as well as the development of techniques to improve the performance of PLC systems at the physical and link layers [14]- [17], there are a number of technical contributions providing understanding into how PLC systems work and pointing out challenging issues related to the advancement of the PLC technology. Although there is a plethora of literature on the general PLC systems, a similar volume is currently not available for coupling techniques in PLC systems.…”

The advent of power line communication (PLC) for smart grids, vehicular communications, internet of things and data network access has recently gained ample interest in industry and academia. Due to the characteristics of electric power grids and regulatory constraints, the effectiveness of coupling between the power line and PLC transceivers has become a very important issue. Coupling devices used to inject or extract data communication signals into or from power lines are very important components of a PLC system. There is, however, an obvious gap in the literature for a detailed review of existing PLC couplers. In this paper, we present a comprehensive review of couplers, which are required for narrowband and broadband PLC transceivers. Prevailing issues that protract the design of couplers and consequently subtended the inventions of different types of couplers are clearly described. We also provide a useful classification of PLC couplers based on the type of physical couplings, voltage levels, frequency bandwidth, propagation modes and a number of connections. This survey will guide researchers, as well as designers alike, into a quicker resourcing when studying coupling in narrowband and broadband PLC systems.
