Abstract: In the acceptance of the wind turbine generator (WTG) grounding project, since each participating units will have a greater dispute on the measurement methods, the WTG grounding acceptance can’t adhere to the scientific and impartial principle. Combining with the requirements of WTG grounding resistance in wind power plant from the WTG manufacturer and IEC standards, and based on the characteristics of the WTG grounding network, this paper focused on the research of the three-electrode grounding resistance testing method and gave the main testing principle and method of the WTG grounding device.
Key words: wind turbine generator grounding device; wind turbine generator grounding network; wind turbine generator grounding resistance; three-electrode method
