ON MAXIMUM POWER FOR AN ELECTROAEOLIAN SYSTEM OPERATING AT VARIABLE WIND SPEED VALUES

Abstract

This paper proposes a simple method for determining the performance of a system composed of a wind turbine – (WT) and a permanent magnet synchronous generator (PMSG). By using the WT and PMSG characteristics, the system equations are deduced, from which can be calculated the basic variables: speed, currents, voltages, couples, operating at points of maximum power for specific wind speed values. For a certain wind speed, one can actually calculate all variables that define the points of maximum power operation.
