Abstract: A reasonable grounding grid design is critical to the safety of persons and equipment. Introduction was made to the IEEE Std 80-2000 which was widely used in the design of foreign substations and grounding grid of power plants. Based on the standard, this paper carried out research on the ground grid design of a 132 kV booster station of certain wind power plant in Pakistan and calculated the grounding resistances, step potential, touch potential and grounding potential rise. The problem that the step potential cannot meet the requirement is solved by adopting a resistance reduction strategy.
Key words: IEEE Std 80-2000; wind power plant; grounding grid; contact potential; step voltage; high soil resistivity
