How does PowerFactory interpret p.u. values for turbine and generator models?

Power Equipment Models
Answer

PowerFactory is using the rated power of the turbine as an additional input parameter to the turbine model and converts the turbine output (in turbine-p.u.) to synchronous machine p.u. at the output of the turbine model:

pt = pt_t*Pnt/Png

where

  • pt Turbine power in synchronous machine p.u.
  • pt_t Turbine power in turbine p.u.
  • Pnt Rated turbine power
  • Png Rated generator power
