“…The findings in [17] show a wireless LAN implementation of the IEC 61850 manufacturing message specification (MMS) protocol to facilitate data exchange among IEDs in a given electrical substation. The authors in [18] explore the implementation of the line differential protection function using IEC 61850 sampled value (SV) and GOOSE communication protocols. In addition, in [19], data acquisition cards and IEC 61850-based real-time simulators for protection relays are compared.…”

Protection relays that incorporate advanced microprocessors are vital to electrical grids, providing fast and reliable responses to faulty conditions using efficient communication protocols. Instant detection and response to various faults are essential to minimise the risk of damage. Numerical relays can identify faulty conditions and trigger circuit breakers to open, thus preventing further damage to the system. Due to the lack of autonomous decision-making capabilities, existing numerical relays require manual reconfiguration in situations such as a change in network configuration and protection settings. These relays also do not have the ability to coordinate fault clearance when multiple sources supply power to the grid. A comprehensive overview of the research aimed at developing a multiagent system (MAS)-based adaptive protection relay will be provided by dividing it into separate articles such as firmware and hardware. This first part delves into the firmware aspects of this innovative relay, highlighting its adaptive capabilities and key considerations in its development. The second part will provide detailed design descriptions for the hardware features of the relay. An STM32MPU multicore advanced microprocessor is utilised to design and develop the adaptive numerical relay firmware. It incorporates several protection relay ANSI codes, communication protocols, and MAS-based adaptive protection schemes as part of the firmware.

The digitization of electrical substations brings great challenges for the commissioning of electrical protections, and interoperability tests must be performed with different equipment. Therefore, this work evaluates the response time of an electrical protection relay operating with sampled values in a digital substation with a process bus. A test scheme is proposed to emulate the process bus based on analyzing the main components in a digital substation with multi-vendor device interoperability. In addition, the delay times of the protection relay with the process bus are measured, considering interoperable infrastructure as a fundamental factor in the system performance. The results are compared with the response times of a conventional relay that operates with analog signals to identify the impact of the digitalization of signals in electrical substations with a process bus. Each relay has an instantaneous overcurrent function adjusted to operate with the same pickup currents at different fault current levels. The results show that tripping times are admissible for the operation of the protection relays, considering three-time measuring points in the test scheme. The time delays found are related to high data traffic in the communication network and the traffic saturation according to the time measuring point. Other delays related to processing SVs in an MU do not represent a risk for the protection scheme. For the industry, the methods presented in the research are useful for configuring and testing electrical substations with different equipment and topologies. In addition, the results presented here seek to generate confidence in companies and engineering teams when migrating to systems with digital substations.

The presence of telecommunications and intelligent devices is increasing in electrical systems. With the IEC 61850 standard, the topology of electrical substations is being modified to the known digital substations. These substations are divided into process, bay, and station levels. With this new topology, there is a need for detailed studies about the behavior of protection, control, and supervising functions to analyze if these functions will not lose performance. Protection functions impose significant challenges with the implementation of the process bus. Important evaluation points are the correct operation of these functions, acting time and fault clearing times, and behavior during process bus contingencies. This paper analyzes the dynamic performance of distance protection using the process bus. The main evaluated points are its acting time, fault clearing times, and performance during process bus contingencies. The results show that the use of the process bus presents an error of 1,96 % compared to the conventional topology in the fault clearing time. In the cases considering concurrent traffic in the process bus, the maximum error is 2,38 %, thus concluding that the process bus does not significantly influence the protection performance. Resumo: A presença das telecomunicações e de dispositivos inteligentes vem se tornando cada vez maior dentro dos sistemas elétricos. Com o surgimento da norma IEC 61850, a topologia das subestações elétricas vem sendo modificada para as conhecidas subestações digitais. Essas subestações são divididas em três níveis: nível de processo, de vão e de estação. Com essa nova topologia, são necessários estudos detalhados sobre o comportamento de funções de proteção, controle e supervisão para analisar se o desempenho dessas funções não será degradado. As funções de proteção impõem um desafio grande com a implementação do barramento de processos. Pontos necessários de avaliação incluem a correta atuação das funções de proteção, tempo de atuação e de eliminação dos defeitos, comportamento durante contingências na rede de comunicação, entre outros. Esse artigo faz uma análise do desempenho dinâmico da função de proteção de distância utilizando o barramento de processos. Os principais pontos avaliados são: tempo de atuação da proteção, tempo de eliminação do defeito e análise do desempenho da proteção sobre contingências no barramento de processos. Os resultados mostram que a utilização do barramento de processos apresenta um erro de 1,96 % em relação a topologia convencional no tempo de eliminação de falta. Nos casos considerando tráfego concorrente no barramento de processos, o erro máximo encontrado foi de 2,38 %, assim conclui-se que o barramento de processos não influencia significativamente o desempenho da proteção.
