prodSFB: Performance of a PV pumping system

Description

Compute every step from solar angles to effective irradiance to calculate the performance of a PV pumping system.

Usage

prodSFB(lat, G0dm, Ta = 25, modoRad = "prom", 
    previo, MAPA, BaseDatos, 
    FormatoFecha = "%d/%m/%Y", Nm = 1, 
    beta = abs(lat) - 10, alfa = 0, iS = 2, alb = 0.2, 
    Bomba, H, 
    Pg, variador = list(Pnom = Pg, Ki = c(0.01, 0.025, 0.05)), 
    EffSys = list(ModQual = 3, ModDisp = 2, OhmDC = 1.5, OhmAC = 1.5))

Arguments

lat

see calcG0

G0dm

see calcG0

Ta

see calcG0

modoRad

see calcG0. If modoRad='prev' a previous result of this function prodSFB is included in previo in order to obtain new results with the same irradiance on the horizonta

previo

data.frame, needed when modoRad='prev'. It is the result of a previous use of this function

MAPA

see calcG0

BaseDatos

see calcG0

FormatoFecha

see calcG0

Nm

see calcG0

beta

numeric, inclination angle of the surface (degrees).

alfa

numeric, azimuth angle of the surface (degrees). It is positive to the West. It is only needed when modoSeg='est'. Its default value is alfa=0

iS

integer, degree of dirtiness. Its value must be included in the set (1,2,3,4). iS=1 corresponds to a clean surface while iS=4 is the selection for a dirty surface. Its default value is 2

alb

numeric, albedo reflection coefficient. Its default value is 0.2

Bomba

list, with Qn, the rated flow of the pump, and Etapas, the number of stages

H

Total manometric head (m)

Pg

Nominal power of the PV generator (Wp)

variador

list containing the nominal power of the frequency converter, Pnom, and Ki, vector of three values, coefficients of the efficiency curve.

EffSys

list of numeric values with information about the system losses, [object Object],[object Object],[object Object]

Value

• list containing:
• I
  data.frame, set of variables describing the evolution of flow and power in a PV pumping system.
• D
  list, result of resumenProdSFB, which is the daily, monthly and yearly summaries of the irradiation, flow and productivity of the system. For details about this list refer to resumenProdSFB
• param
  list which contains the main parameters of the calculation.

Details

The calculation of the irradiance on the horizontal plane is carried out with the function calcG0. The transformation to the inclined surface makes use of the fTheta and fInclin functions. The performance of the PV system is simulated with fBomba. The PV generator is on a fixed surface.
