Abstract:The global climate is deteriorating day by day, and China has also made commitments to "peak carbon emissions and carbon neutrality". A large number of new energy sources such as solar energy and wind energy are connected to the power grid. At the same time, with the development of China"s urbanization process, urban power grid grounding projects, and a large number of cables are used in urban power grids. The "two priorities" are written into the safety production law, which puts higher requirements on safety, A new issue has been proposed regarding the neutral point grounding method in the distribution network under the new power system and new situation. This article analyzes the current problems of neutral point grounding in distribution networks, proposes the influencing factors of neutral point grounding in high-voltage distribution networks under new power systems, systematically analyzes the effects of ungrounded, arc suppression coil grounding, and low resistance methods on overvoltage, equipment selection, and manufacturing, elaborates on the advantages and disadvantages of the three methods, and finally summarizes the applicable conditions of high-voltage distribution network grounding methods, providing a basis for engineering design and practice.
