Abstract

The objective of this Work is to provide a vector control combined with an electric asynchronous motor. The configuration of this system includes a photovoltaic generator (PVG), a PV bus, a PV filter connected to a boost converter, a DC bus and a voltage inverter fed induction machine coupled to a centrifugal pump. To ensure operation at maximum power of PV system for various climatic conditions, the MPPT (Maximum power point tracking) control is used. At the end of control flow and total head of pumping station, the control strategy for flux vector oriented FOC (flux oriented control) served here as a solution. Simulation results show the effectiveness of different commands used in this system.

Key words: Photovoltaic; MPPT; flux oriented control; asynchronous machine.
