System Performance
Defined as ensuring the Wind system meets the requirements of the ISO or Utility Large Generator Interconnection Agreement and all of the applicable FERC/NERC Standards.
This task starts with a a series of studies on the complete project - WTG to the Point of Interconnection (POI) :
Load flow study Short-circuit study Harmonic study Insulation Coordination study Dynamic and transient stability study Grounding and neutral grounding study Electromagnetic interference study Voltage fluctuation study
