Synthetic Power Curve¶

• RESKit allows synthetic power curves to be created in case they are not known

Workflow:

1. Import required packages
2. Calculate power curve from given capacity and rotor diameter
3. Calculate power curve from given specific capacity
4. Calculate power curve from given specific capacity and cutoff wind speed

In [1]:

import reskit as rk

import reskit as rk

In [2]:

# Power curve from a given capacity (kW) and rotor diameter (m)
pc = rk.wind.PowerCurve.from_capacity_and_rotor_diam(capacity=3000, rotor_diam=140)

pc

# Power curve from a given capacity (kW) and rotor diameter (m) pc = rk.wind.PowerCurve.from_capacity_and_rotor_diam(capacity=3000, rotor_diam=140) pc

Out[2]:

In [3]:

# Power curve from a specific capacity (in W/m2)
pc = rk.wind.PowerCurve.from_specific_power(specific_power=250)

pc

# Power curve from a specific capacity (in W/m2) pc = rk.wind.PowerCurve.from_specific_power(specific_power=250) pc

Out[3]:

In [4]:

# Adjustable cutoff wind speed
pc = rk.wind.PowerCurve.from_specific_power(specific_power=250, cutout=30)

pc

# Adjustable cutoff wind speed pc = rk.wind.PowerCurve.from_specific_power(specific_power=250, cutout=30) pc
