---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - The use of induction generators to generate electricity from unconventional sources has attracted considerable interest from energy researchers. Based on economy, high technical knowledge and environmental friendliness to provide electricity used for all development. Wind energy plays an important role in developing an environment friendly economy with low carbon footprint. This paper provides an overview of wind turbine generator technology and compares the advantages and disadvantages when applied to wind energy applications. Traditionally, DC motors, synchronous motors, and squirrel-cage induction motors have been used to generate small electrical currents. For medium and large wind turbines, doubly-fed induction generators are currently the dominant technologies, while permanent magnetic, switched reluctance and high-temp superconducting generators have been extensively researched and developed over many years. This paper discusses the topology and characteristics of these devices, including their practical considerations regarding design, control and operation.
industrial policies. The 1990s also saw a shift in focus from onshore to offshore development in key wind developing countries, particularly in Europe, Offshore wind farms were first proposed in Germany in the 1930s, first installed in Sweden in 1991 and in Denmark in 1992. By July 2010, offshore wind turbines were installed 2.4 GW established in Europe Compared to onshore wind, offshore wind energy has some interesting properties such as wind speed.
The paper presents a summary of wind turbine technology through a literature review of wind turbine systems followed by a discussion of systems applied on doubly fed induction generator wind turbines in particular.
Fig -1: Ever-growing size of horizontal-axis wind turbines. Over the past three decades, wind turbines have experienced tremendous growth as the global wind market continues to grow and accelerate. At the end of 2009, global capacity was 160 GW. The contribution of wind energy to the global electricity market is estimated to increase from 1% in 2008 to 8% by 2035. This can only be achieved by building larger wind turbines and putting more into the wind industry. In terms of scale, large megawatt wind turbines are starting to appear in the EU, the US, and now China and India. Typically the largest wind turbines installed in utility grids are 1.5-5 MW while 7.5 to 10 MW are in high development, as shown in Fig-1, Modern wind turbines are now Reliable, quiet, costeffective and commercially competitive, while wind turbine technology has been demonstrated are also proficient. Current technical challenges are generally related to everincreasing wind turbine size, power transmission, energy storage, energy efficiency, complex design and fault tolerance .Nowadays, it is widely recognized that wind power is the main source of economically viable renewable energy available. A global map of wind power potential is shown in Figure 2. However, wind power is variable in nature and such applications require high reliability and are

1. INTRODUCTION 1.1 .Utilization of wind energy Wind energy was used as early as 5000 B.C. when they sailed across the Nile. It is recorded that in 200 B.C. Since then, wind has been used as an energy source in ancient China and the Middle East to pump water, grind rice, and propel cars and ships. The first recorded windmill was built in the first century B.C. or the first century AD. Effectively, this wind turbine is used to convert kinetic energy into mechanical energy. These wind turbines themselves tend to be small (less than 100kW) but can be designed for larger wind turbines (5MW or specified). Until the early 1990s, wind projects literally got off the ground, driven primarily by government and
