define_turbine

Source: R/define_inputs.R
define_turbine.Rd

make a list of turbine parameters for input into the default CRM

Usage

define_turbine(
  model_id,
  blade_length,
  blade_thickness_narrow,
  blade_thickness_wide,
  d_base,
  d_rotormin,
  d_top,
  hh,
  max_chord,
  min_chord,
  max_nac_h,
  max_nac_l,
  max_width_nacelle,
  rotor_diam = NULL,
  rpm,
  tilt_deg,
  prop_operational = 1
)

Arguments

model_id

character; Label for turbine model - allows the user to define multiple turbine types on a site

blade_length

blade length (m)

blade_thickness_narrow

the thickness of the blade (side on) at its thinnest point (m)

blade_thickness_wide

the thickness of the blade (side on) at its widest point (m)

d_base

diameter of tower at base (m)

d_rotormin

diameter of tower at base of rotor (m)

d_top

diameter of tower at top (m)

hh

hub height (m)

max_chord

the chord of the blade at its widest point (m)

min_chord

the chord of the blade at its tip (thinnest point) (m)

max_nac_h

max nacelle height (side view) (m)

max_nac_l

max nacelle length (side view) (m)

max_width_nacelle

diam of nosecone == nacelle room width (back view) (m)

rotor_diam

if unspecified, defaults to 2*blade_length + max_width_nacelle (m)

rpm

rotational speed of turbine (rpm)

tilt_deg

Blade tilt in degrees

prop_operational

numeric; Proportion of a 24 hour day that turbines are operational. A single number or distribution information using set_random. Default 1

Value

list where items define the value or stochastic distribution for each parameter

Details

Makes a list of parameters for the a given turbine

Details

Each input to this function must be either

  • an object of the class randInput. See set_random for more information on setting up stochastic inputs.

  • a single number representing the average (preferably median) of the variable
