PCTrainTurbineModel: Create an IEC-conformal power curve

In AndyClifton/PowerPerformance: Package to analyze wind resource and wind turbine data (developer test version)

Description

PCTrainTurbineModel creates a wind turbine power curve using the method described in IEC 61400-12-1 (2005).

Usage

PCTrainTurbineModel(ws, power, ti = rep(NA, length(ws)), power.rated = NA,
  ws.delta = 0.5, ws.cutin = 3, ws.min = 0.25,
  ws.max = (round(max(ws)/ws.delta) * ws.delta) - ws.delta)

Arguments

ws	wind speed observations
power	power observations
ti	(optional) the observed turbulence intensity
power.rated	(optional) the rated power of the turbine generator
ws.delta	(optional, default = 0.5 m/s) the width of the bins
ws.cutin	(optional, default = 3 m/s)
ws.min	the minimum wind speed, below which power = 0
ws.max	the maximum wind speed to bin data to

Details

The input windspeed is assumed to have been corrected for density.

Value

a data.frame containing

ws.binmin

The minimum wind speed in that bin

ws.binmax

the maximum wind speed in that bin

ws.binnpoints

The number of observations (points) in that bin

ws.binmean

The mean wind speed in that bin

ti.binmean

The mean turbulence intensity in that bin (NA if no Ti given)

power.binmean

The mean power in that bin

power.binsd

The standard deviation of the power in that bin
