“…In [106] A performance comparison between two teleprotection interfaces can be seen in [107]. The first one is based on a conventional teleprotection framework, supported by IEC 60834-1 standard, while the second one is implemented using a structure similar to the gateway communication system presented in IEC 61850 part 90-1.…”

“…The adoption of IP technologies by the power utilities for mission-critical scenarios are getting closer, once the proposed smart grids ideals are more widespreaded on the power industry, tied to the benefits offered by these technologies and the end of the life cycle of TDM technologies. Thus, the MPLS technology is a relevant name for the scenario in the coming years [236], specially in developing countries, such as Brazil, India, etc.…”

The appeal for more reliable, efficient and resilient power grids has become indispensable with the recent technological development and ever-increasing demand for electrical energy. These goals might be achieved by introducing sensors and actuators in the power grid, with the purpose of enabling a smart control of the power network. All power devices must be connected using a reliable communication network, which should be able to operate even when the power grid fails. Currently, several communication technologies have been applied for supporting this new application scenario. This paper aims for reviewing both academic and market use cases for technologies applied to the mission-critical, control networks and Smart Grid applications, such as teleprotection, self-healing, communication with control centers and field devices, among others. More specifically, the key aspects, potential technologies, main protocols and use cases of operating data networks in energy transmission, power distribution and smart grid environments, including circuit and packet switching technologies, are discussed into details. Furthermore, resilience and the main telecommunications technologies used in power grids, as well, the correlation among them, are exploited in practical point of view. The article provides a broad discussion on the best telecommunication options to build the emerging intelligent energy distribution systems, covering control networks, teleprotection, and smart grid applications.

“…Para a validação do estudo, resultados de aplicações em campo e testes em laboratório foram utilizados. Rahman et al (2018) reportam os resultados de testes utilizados na preparação da migração das redes que interligam relés de proteção da subestação San Diego Gás & Electric (SDG&E) de SONET para MPLS. Os testes apresentados foram realizados tanto em laboratório, quanto em modelo de simulação usando o Real Time Digital Simulator (RTDS).…”

O consumo energético vem crescendo continuamente, sustentando o modelo social atual. Neste cenário, as concessionárias de energia proveem meios de interligar as fontes geradoras aos consumidores finais. Sistemas como os de teleproteção são utilizados para garantir que as falhas presentes nas redes elétricas não afetem os consumidores. Tradicionalmente, as concessionárias de energia utilizam tecnologias de multiplexação por divisão de tempo (do inglês, Time-Division Multiplexing - TDM), como meio de comunicação para os sistemas de teleproteção, porém a sua ineficiente alocação de recursos e o seu final de ciclo de vida vem possibilitando a utilização de novas tecnologias, tais como as baseadas no protocolo Internet (do inglês, Internet Protocol- IP). Deste modo, esse trabalho avalia o desempenho de redes estatísticas para o serviço de teleproteção, apresentando resultados laboratoriais com equipamentos utilizados em campo. Os resultados dos testes indicam uma potencial viabilidade da utilização de redes estatísticas em relação aos requisitos operacionais de teleproteção, constituindo um passo importante para a realização de implementações em campo. No entanto, mais testes serão necessários para a prova definitiva dessa viabilidade.

“…One method addressing latency and asymmetry requirements for tele-protection communications is high priority provisioning using Quality of Service (QoS) prioritization [5]. This ensures that tele-protection traffic packets do not incur additional latency due to queuing which is caused by waiting for larger, lower priority packets to be processed.…”
