A REPORT ON

INDUSTRIAL VISIT TO M.P. WIND FARMS BY THE STUDENTS OF ELECTRICAL AND ELECTRONICS

ENGINEERING DEPARTMENT

Venue: Dewas

Date: 08/03/2014

INTRODUCTION

In this era of depleting non-renewable resources, technology has to adapt according to it and think of more innovative and eco-friendly ideas for power generation. One of them being wind energy, although it is used throughout the world but still comprises of a small percentage of global power generation. Many of the largest operational onshore wind farms are located in the United States and China. For example, the Gansu Wind Farm in China has a capacity of over 5,000 MW of power with a goal of 20,000 MW by 2020. In India development of wind power began in the 1990s, and has significantly increased in the last few years. Although a relative newcomer to the wind industry compared with Denmark or the United States, India has the fifth largest installed wind power capacity in the world.[1] In 2009-10 India's growth rate was highest among the other top four countries. Wind power accounts for 8.5% of India's total installed power capacity, and it generates 1.6% of the country's power.

MADHYA PRADESH (386 MW)In consideration of unique concept, Govt. of Madhya Pradesh has sanctioned another 15 MW project to Madhya Pradesh Wind farms Ltd. MPWL, Bhopal at Nagda Hills near Dewas under consultation from Consolidated Energy Consultants Ltd. CECL Bhopal. We had the privilege of visiting one of these wind farm in Dewas district which makes an a annual power of 1.84 Mw.

TECHNICAL DISCRIPTION

On the trip we were guided by Mr. A.K. Bhaumik, he explained us about the overall process of wind utilization, power generation, structure, transmission and receiving. We also did step into a windmill to study the various measuring devices, startup panels, and safety mechanism.

The following are some of the key points he pointed out for us:-

It was setup in 1995, the parts were imported from Denmark. The power plant gives a total generation of 300,000 units per annum. For one rotation of blade shaft the rotor of generator rotated 40 times, using gear

system. Generator rating- 225kW

Wind speed range -2.5m/sec to 18 m/sec, after this limit the safety mechanism for the rotor would break the rotors, as beyond this speed it can inflict damage on itself and the generator.

The casing was made out of iron. Each wind turbine has 2m base dia., 30 m height ,13m long blades(3 Blades) Blade material- Aluminum and composite materials/fillers. Installation cost per wind turbine- Rs.11,000,000 There are 58 such wind turbines. Annual maintenance cost-2% of initial cost. Every generator has its own auxiliary transformer 315 KVA, all of which then I

transferred to a central grid for the wind farm, which then transfers it to nearest substation for distribution.

He also mentioned that this setup will only be working till 2016 after which the 30m wind turbines will be replaced by 50 wind turbines, hence increasing the total output generated significantly.

FEEDBACK

The educational visit proved to be very beneficial for us. We came to know about the power generation through wind mills. The working action of wind mills were very well explained by the staff member. He gave an elaborate description of the constructional and working features of the wind mills. He

also informed us about its establishment and maintenance procedures.

This type of visit should be conducted on regular basis and some more modification should be done in industrial training, few of them are enlisted below-

Companies should be invited to offer training to the students of pre-final year of various departments in the campus itself, whose selection criteria should be based on the personal interview.

Industrial collaboration should be made by the college to provide better exposure to the practical outside world. This would enhance the growth of student as well as that of college.

This type of industrial visit and training would help the students to apply their knowledge to practical areas.
