Double-fed asynchronous generator for wind power

Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. By feeding adjustable-frequency AC power to. . This chapter introduces the operation and control of a Doubly-fed Induction Generator (DFIG) system. The DFIG is currently the system of choice for multi-MW wind turbines. We help our customers, partners and equipment manufacturers to improve energy efficiency, asset reliability, productivity, safety and performance. They are called "doubly fed" because both the stator and rotor are fed with electrical power. This article explores the. .
