get_lac_factor {stochLAB}

Large array correction factor

Description

A correction factor for large windfarms with a large array of turbines, to take into account the depletion of bird density in later rows of the site.

Usage

get_lac_factor(
  n_turbines,
  rotor_radius,
  avoidance_rate,
  avg_prob_coll,
  avg_prop_operational,
  wf_width
)

Arguments

n_turbines

Integer, the number of turbines on the wind farm (T).

rotor_radius

Numeric value, the radius of the rotor (R), in metres.

avoidance_rate

Numeric value within the interval [0, 1]. The species avoidance rate, expressing the probability that a bird flying on a collision course with a turbine will take evading action to avoid collision. (A).

avg_prob_coll

Numeric value, the average probability of collision for a single bird transit through a rotor, assuming no avoidance action (p_average).

avg_prop_operational

Numeric value, the average proportion of time turbines are operational through the year.

wf_width

Numeric value, the approximate longitudinal width of the wind farm, in kilometres (w).

Value

The large array correction factor to be applied
