Analysis and Control Technology for Wind Power Stations

  • Digital Innovation Laboratory
  • Energy Solution
  • Energy Creation
  • Safety and Security
  • Technology of reliable power transmission maintaining quality of renewable energies
  • Analysis of voltage and current abnormality in power transmission lines
  • Harmonic suppressing by controlling reactive power compensators and batteries

Wind power stations have risks of power quality deteriorating when voltage fluctuations occur due to power system conditions, or when harmonics expand (resonate) due to cables and filters.

The technology is being developed to simulate this deterioration in power quality, and to suppress and control abnormal voltage and current.
