Analysis on Operation Principle of Doubly-Fed Wind Power Generator

Abstract

Basing on its advantages, doubly-fed wind power generator has become one of mainstream model of wind power generator which is connected with power network directly. But at present there is no relevant articles that can describe the operation principle of doubly-fed wind power generator in detail. The electromagnetism relation of doubly-fed wind power generator is discussed detailedly in this paper based on the basic theory of AC motor, and finds the equivalent circuit and vectorgraph, analyzes the energy transfer relation. This thesis offers theory basis for the design and control of doubly-fed wind power generator.
