People of the world are in need to find and develop new sources of energy to power their lives. Owing to the increasing demand for electrical energy, world’s fossil fuel supply will thus be depleted in a few decades. Hence, alternative or renewable sources of energy have to be developed to meet the future energy requirement. Grid connected wind capacity is undergoing through fastest rate of growth compared to any other form of renewable power generation, achieving global annual growth rates of 20–30 %. The power electronic converters play a major role in wind energy conversion system for controlling and conditioning of output power from wind energy. During last few years matrix converters and multi level converter topologies have generated significant interest. This paper discusses the diode clamped multilevel matrix converter design for double fed induction generator based wind energy conversion system. The MATLAB/SIMULINK software is used for analyzing the converter performance.

1. INTRODUCTION
Energy plays a vital role
The main purpose of the wind energy is to create energy source which is pollution free and come with a reasonable price. The wind energy used in wind turbines are increasing their demand and becoming popular in the green energy world. Since the rebirth or rapid growth of wind energy took place from early 1980. The growth of the industry has been more than expectations. As all the good things the wind energy poses certain negative impacts of having high maintainer cost. Repair and data collection should be monitored regularly of the turbine to get the idea of placing a new wind energy plant or to maintain the old one. This paper explains the modeling of Wind Energy Conversion Systems and their technologies which is used for the generation of wind power and control strategies of the conversion system.

This is to certify that Mr. Bhavesh Purohit, 12226, student of B.Tech in ASET (Department) has carried out the work presented in the project entitle "Design of Wind Turbine" as a part of Second year programme of Bachelor of Technology in Mechanical and Automation Engineering from Amity School of Engineering and Technology, Amity University, Noida, Uttar Pradesh under my supervision.
Wind power can be produced by air flow turning wind turbines or sails, often used to create mechanical or electrical power. As one of the clean and recycle energy, more and more countries pay attention to wind power. According to the recent EU analysis for the new constructions, the cost of the wind power has fallen to a fifth of that cost in the 20th century during the last 10 years, due to use the new method of math modeling and the new technology of the electrical component. With the development of the analysis in wind power, engineering mathematics takes an important part in using the wind to produce electrical
Since 1980’s wind turbines have noted a remarked progress making the whole sector and technology mature in order to enable the rapid growth on the market. This is justified by Fig.3 where it is observed that from 1996, the growth is steadily increased till 2012 and is still growing. From then till now, the cost
New era that will not mainly relay on central power stations seems to have started. A novel independent power producers who provide less expensive, more efficient and smaller-scale power plants is well underway [1]-[2]. Renewable energy is heavily involved in such direction and
Power electronic converters, especially DC/AC inverters have been extending their range of use in industrial application because they provide better system efficiency, reduced energy consumption and improved quality of power. The output voltage of inverter could be fixed or variable at a fixed or variable frequency and output waveforms are therefore made up of discrete values, producing fast transition rather than smooth ones [2]. The ability to
This new technology has replaced many of the old ones, bringing many advantages to the user, for example DC & AC drives, soft stators, UPS, etc. Since this new technology is rapidly gaining in the modern industries, power systems are expected to provide an ideal sinusoidal waveforms for currents and voltages,
Li et.al[5] suggested Newton Raphson load flow method with wind power. Asynchronous and double fed induction generator were explained in detail and accordingly Jacobian matrices were suggested. An IEEE 5 bus system was used for case study which proved that the new NR method had a good convergence hence could be used for calculations for large grid with wind power. Steady state equivalent circuit for AG and DFIG were also discussed in the paper.

This report aims to discuss the working of DC-AC converter for photovoltaic systems and how it has been implemented to convert renewable energy into usable power to be supplied to the load (power supply application).A topology of a two-stage DC-AC converter has been designed in which a boost converter and a full bridge inverter act as an interface between the photovoltaic (PV) array and the power supply applications. A controlled strategy called Maximum Power Point Tracking (MPPT) technique has been used for achieving maximum power output at the load. Various modes of operation of the converter and the inverter are also discussed. MATLAB Simulink environment has been used for designing the circuitry and to observe various waveforms related to the output.
The American inventor Charles F. Brush invented the first automatically operated wind turbine in 1887. [1] Since then, multiple developments have contributed to the design of today’s modern wind turbine. And when grouped together into a wind farm, wind turbines are becoming an important source of renewable energy.

So that the voltage and current is of poor qualities and the switching frequency causes more amount of switching losses. Those drawbacks are rectified using three phase neutral point clamped multilevel inverter. The voltage and current quality are better and the switching losses are reduced when compared to the conventional technique. Also the THD is found to be better.
