THE ELECTRICAL CONVERSION SYSTEMS AND FUNDAMENTALS OF WIND TURBINE OPERATION

Abstract

This article provides a synopsis of wind turbine electrical conversion technologies. A brief overview of the electric system's needs is followed by a review of the fundamentals of wind energy conversion using wind turbines. Up next, we'll go over the pros and drawbacks of the three traditional conversion methods: constant speed, variable speed with a doubly-fed induction generator, and variable speed with a direct-drive generator. We will quickly go over the power electronic converters that are used in this context. We wrap off by talking about some of the latest developments and alternate generation methods. The use of systems with variable speeds is becoming more common. More and more systems that use doubly-fed induction generators have the ability to ride through grid faults. Compared to electrically stimulated synchronous generators, radial flux permanent-magnet synchronous generators are more efficient and cost- effective for direct-drive turbines. Generator voltages are anticipated to rise to levels of 5 kilovolts.
