“…Thus, the magnitude current value also increases, causing malfunction of protective devices as well. Simple protective devices are proposed and utilised on the radial distribution system, such as the overcurrent [6][7][8], reclosers [9,10], and fuses [11,12]. Losses of coordinated protective devices are concerned with the processes observed, such as loss of tripping, loss of action, and loss of trip command to another device [13,14].…”

This study aims to evaluate the impact of the distributed generator (DG) connection to the grid. The simulated results present the parameters of the system required to install DG on the end of the main distribution feeder. Various parameters, such as voltage, current, and protective relay coordination are modelled after the actual provincial electricity authority (PEA) distribution system. Various case studies compared the coordination without and with DG connections to the grid by finding the difference of protective devices. The results indicate that the malfunction can be fixed in order of priority protective devices, which operate according to the parameter setting. Additionally, the coordinate functions between the recloser and fuse devices in both phase and ground configurations in the operating zone prevented the drop-out fuse melting or burning out. Based on the result, this problem is fixed by providing a directional recloser device and increasing the fuse-link rated with 40k installation for replacing the conventional sizing, which can improve the performance in case of fault occurrence to investigate the reliability and stability of the distribution system.

“…A inserção de GD pode alterar de forma significativa o desempenho de esquemas de proteção, exigindo adequações para garantir seu adequado funcionamento. Dentro desse contexto, estudar os impactos causados pela integração de GDs é essencial, permitindo aperfeiçoar procedimentos Sociedade Brasileira de Automática (SBA) IX Simpósio Brasileiro de Sistemas Elétricos -SBSE 2022, 10 a 13 de julho de 2022 ISSN: 2177-6164 1593 DOI: 10.20906/sbse.v2i1.3092 relacionados ao acesso de GDs às redes de distribuição (Yousaf et al, 2021;Haque et al, 2021).…”

This paper evaluates different scenarios of single-phase faults in the medium voltage system operating in island and supplied by distributed generation (DG) with synchronous generator in steady state, observing the resulting overvoltages due to the delta connection in the primary of the coupling transformer. In this context, the present document proposes to contribute to the technical issues related to the connection of DG, presenting a series of simulations carried out in ATP Draw, considering installations framed in the simplified primary standard. It is not intended here to exhaust all possible technical possibilities but rather to assess how each of the main parameters influences the overvoltages resulting from single-phase faults and whether or not the neutral overvoltage protection function (ANSI 59N) is mandatory for these installations. The results indicate that significant overvoltages may occur in the system depending on load, generation, and fault impedance conditions. Resumo: Este trabalho avalia diferentes cenários de faltas monofásicas no sistema de média tensão operando em ilha e alimentado por geração distribuída (GD) com gerador síncrono em regime permanente, observando as sobretensões resultantes devido à conexão delta no primário do transformador de acoplamento. Neste contexto, o presente documento propõe-se a contribuir para as questões técnicas relacionadas com a conexão de GD, apresentando uma série de simulações realizadas em ATP Draw, considerando instalações enquadradas no padrão de entrada primário simplificado. Não se pretende aqui esgotar todas as possibilidades técnicas possíveis, mas sim avaliar como cada um dos principais parâmetros influencia as sobretensões resultantes de faltas monofásicas e se a função de proteção de sobretensão de neutro (ANSI 59N) é obrigatória ou não para essas instalações. Os resultados indicam que podem ocorrer sobretensões significativas no sistema dependendo das condições de carga, geração e impedância de falta.
