Attribute
Public PU
  dfimax
Details:
Notes: Maximum rate of change of frequency (<i>dF</i><i><sub>max</sub></i>). It is type dependent parameter.<br/>
Public PU
  fover
Details:
Notes: Wind turbine over frequency protection activation threshold (<i>f</i><i><sub>over</sub></i>). It is project dependent parameter. <br/>
Public PU
  funder
Details:
Notes: Wind turbine under frequency protection activation threshold (<i>f</i><i><sub>under</sub></i>). It is project dependent parameter.<br/>
Public Boolean
  mzc
Details:
Notes: Zero crossing measurement mode (<i>Mzc</i>). True = 1 if the WT protection system uses zero crossings to detect frequency – otherwise false = 0. It is type dependent parameter.<br/>
Public Seconds
  tfma
Details:
Notes: Time interval of moving average window (<i>TfMA</i>). It is type dependent parameter.<br/>
Public PU
  uover
Details:
Notes: Wind turbine over voltage protection activation threshold (<i>u</i><i><sub>over</sub></i>). It is project dependent parameter.<br/>
Public PU
  uunder
Details:
Notes: Wind turbine under voltage protection activation threshold (<i>u</i><i><sub>under</sub></i>). It is project dependent parameter.<br/>
