“…Due to its numerous profits, such as the reduced cost, brushless rotor structure, roughness, and simplicity of maintenance, the autonomous induction generator which is also known as the self-excited generator is widely used in wind power converting requests [1]. The main difficulty encountered with the use of this kind of generator is to ensure the output stator voltages regulation simultaneously in magnitude and frequency with respect to the load changes and fluctuations in rotor speed [2,3].…”

This paper proposes a novel idea to governing wind power conversion plants supplying DC loads characterizing an isolated site based on self-excited squirrel-cage induction generators (IG). In this wind power converting application, the induction generator produces an active power from the mechanical power provided by a wind-turbine to variable DC loads through a static converter with an output capacitor under constant voltage levels. For this reason, A specific vector control technique has been developed for controlling the induction machine in an analogous manner with a separated DC machine case. Thus, in order to satisfy the active power demand characterizing a variable DC load at a given rotor mechanical speed, the corresponding control laws are performed in steady-state conditions from a new control variable introduction defined by the ratio of the desired output DC-bus voltage square value and the rotor velocity. Computer simulations validated by experimental results demonstrate that the projected control approach including just one conventional controller ensures excellent tracking performances of the DC-bus voltage to its reference trajectory under simultaneous variations of the load-power demand and the rotor velocity profiles.
