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.

Equivalent Circuit Models

There has been a growing interest in building equivalent circuit models for lithium-ion battery with evolutionary algorithms. One of the well-known algorithm is the Hoeffding bound based evolutionary algorithm (HEA). In this paper, we first introduce the definitions of the Hoeffding bound, selection operations and Hoeffding evolutionary algorithm. And then, we introduced the method for building equivalent circuit models, which composed of four fundamental functions, connection-modifying function, component-creating function, arithmetic-performing functions and automatically defined function. In this way, a Hoeffding-evolutionary-algorithm based equivalent-circuit-model for lithium-ion battery is modeled. With the model-based state estimation approaches, the obtained model can assess the state-of-charge (SOC) of cells precisely.
