摘要：
The protection technology of the distribution network with distributed generation is critical for the safe and stable operation of the new power distribution system. As large-scale distributed new energy sources are connected to the distribution network, the traditional reclosing and current three-stage protection cannot meet safe operation needs. It is urgent to study new relay protection technologies for distribution networks. However, the distribution network protection research still lacks a systematic summary and induction. Therefore, this paper reviews the research on new distribution network protection based on the structure and protection requirements of the distribution network with distributed generation. First, the distribution network protection configuration is introduced, and the impact of distributed generation on distribution network protection under different working modes, access capacities and locations, and different types of power supply scenarios is analyzed. Secondly, we analyze and summarize the protection technology based on the current research on short-circuit protection and control of distribution networks with distributed generation at home and abroad. Finally, combined with the research status of distribution network protection and the demand for distributed new energy access, the research direction of new distribution network protection under the high penetration rate of distributed generation is discussed. © 2023 Science Press.
