Wave Power {renpow}

Wave Power Functions

Description

Calculations in wave power generation

Usage

generate.duration(file)
powflux.wave(Hs, Tp)
wave.contour(X,label,sum, sumlabel)
duration.wave(datafile, file=TRUE)
energy.wave(Pflux, D)
energy.gen(Ew, L, nu)

Arguments

datafile

either a data file name or a renpow dataset

file

a logical to decide between a data file or a dataset

Hs

height in HsTp matrix

Tp

duration in HsTp matrix

X

Object to plot as contour; can be Pflux, Ew, or Eg

Pflux

Power flux produced by powflux.wave function

Ew

Energy produced by energy.wave function

label

label for plot; the default is ""

sum

logical default TRUE

sumlabel

label for sum; the default is ""

D

duration produced by duration.wave function

L

length of structure or energy conversion device

nu

efficiency

Details

Basic calculations for wave power

Value

Eg

Energy produced by energy.gen function

Examples

 Pflux <- powflux.wave(Hs=seq(1,10),Tp=seq(5,20)) 
 wave.contour(X=Pflux,label="Power flux (kW/m)")
 D <-  duration.wave(WaveHsTp,file=FALSE)
 # alternatively using file in extdata 
 #  D <- duration.wave(system.file("extdata","WaveHsTp.csv",package="renpow"))
 wave.contour(X=D,label="Duration (hrs/yr)")

 Ew <- energy.wave(Pflux,D)
 wave.contour(X=Ew,label="Energy flux (MWh/yr/m)",sum=TRUE,sumlabel="(MWh/yr/m)")
 Eg <- energy.gen(Ew,L=30,nu=0.4)
 wave.contour(X=Eg,label="Energy produced (MWh/yr)",sum=TRUE,sumlabel="(MWh/yr)")
