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