Class "ProdPVPS": performance of a PV pumping system.

Description

Performance of a PV pumping system with a centrifugal pump and a variable frequency converter.

Objects from the Class

Objects can be created by prodPVPS.

Slots

prodI:

Object of class "zoo" with these components:

Q:: Flow rate, (m³/h)
Pb, Ph:: Pump shaft power and hydraulical power (W), respectively.
etam, etab:: Motor and pump efficiency, respectively.
f:: Frequency (Hz)

prodD:

A zoo object with daily values of AC energy (Wh), flow (m³) and productivity of the system.

prodDm:

A zoo object with monthly means of daily values of AC energy (kWh), flow (m³) and productivity of the system.

prody:

A zoo object with yearly sums of AC energy (kWh), flow (m³) and productivity of the system.

pump

A list extracted from pumpCoef

H

Total manometric head (m)

Pg

Nominal power of the PV generator (Wp)

converter

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

Besides, this class contains the slots from the Gef class.

Extends

Class "Gef", directly. Class "G0", by class "Gef", distance 2. Class "Meteo", by class "Gef", distance 3. Class "Sol", by class "Gef", distance 3.
