With the increasing number of renewable energy plants connected to the power system, the gap grounding mode is often adopted by the high-voltage side neutral point of the interconnecting transformer of the renewable energy plants in order to improve the performance of the zero sequence protection. In practical engineering applications, the low-voltage side of the …
Globally, around 1.1 billion people do not have access to electricity and 84% of the population who do not have modern energy access are living in rural and remote areas of developing countries. Since the loads are far from the grid and providing the connection by extending from the main grid requires a high investment associated with long and costly …
The conventional neutral grounding methods can be categorized into three distinct types: solid grounding, arc suppression grounding (ASG), and high-resistance grounding (HRG). The selection of the appropriate method is contingent upon multiple factors, including the system''s scale, voltage level, and the specific protection schemes employed.
