Voltage and Current Inrush Control of Wind Driven Embedded Wound Rotor Induction Generator

ABSTRACT With the depletion of fossil fuel reserves and an increase in interest in renewable energy generation systems, embedded renewable energy generation (EREG) has become increasingly common. A number of reasons limit the addition in capacity of generating units at the substation busbar (embedded generation). Voltage related a problem such as steady-state voltage rise is a major limiting factor. Techniques such as power factor control; network reinforcement and load control to regulate the voltage has been used to limit the steady-state voltage rise. In this paper, a new scheme is proposed which limits the voltage rise problem of induction generators used in wind energy conversion systems (WECS) and simultaneously reduce the magnetising current to a large extent at generator cut-in.
