Hello!
I'm currently using PySAM and wanted to clarify the documentation on the WindPower Losses class.
In the
documentation
, most losses are marked "If not provided, assumed to be 0."
However, for the following model...
d = wp.default("WindPowerNone")
d.Resource.wind_resource_model_choice = 0 # hourly
d.Resource.wind_resource_filename = windSRW # srw filename
d.Turbine.wind_turbine_powercurve_powerout = powerout # ndarray
d.Turbine.wind_turbine_powercurve_windspeeds = speed # ndarray
d.Turbine.wind_turbine_hub_ht = 100
d.Farm.wind_farm_xCoordinates = [0]
d.Farm.wind_farm_yCoordinates = [0]
d.execute()
The losses are assigned as follows:
Balance-of-plant = 0.5
Grid availability = 1.5
Turbine availability = 3.58
Electrical efficiency = 1.91
Electrical parasitic = 0.1
Environmental degradation = 1.8
Environmental conditions = 0.4
Environmental exposure = 0.0
Environmental icing loss = 0.21
Environment curtailment = 1.0
Grid curtailment = 0.84
Load curtailment = 0.99
Operational strategy = 0.0
Turbine generic = 1.7
High wind hysteresis = 0.4
Sub-optimal performance = 1.1
Site-specific loss = 0.81
External wake loss = 1.1
Future wake loss = 0.0
Internal wake loss = 0.0
Just curious if this mismatch is intentional and/or if I missed an important dependency.
Thanks (:
