defining wind power
Defining Wind Power
  • Wind power is the conversion of wind energy into a useful form of energy, such as electricity, using wind turbines
  • Wind energy systems convert the kinetic energy to more useful forms of power
  • Wind energy continues to be the fastest growing Renewable Energy Source with worldwide wind power installed capacity reaching 14,000 MW
  • Five nations – Germany, USA, Denmark, Spain and India – account for 80% of the world’s installed wind energy capacity
why renewable
Why Renewable ?
  • Global climate change threatens our economy, national security and the physical landscape itself, denying the urgency of global warming. That is why we cannot abandon the Kyoto Protocol, which calls for industrialized nations to take the lead in reducing greenhouse gas emissions
  • Carbon credits are a key component of national and international attempts to mitigate the growth in concentrations of greenhouse gases (GHGs). One Carbon Credit is equal to one ton of Carbon. Carbon trading is an application of an emissions trading approach
  • The objective of the Kyoto climate change conference was to establish a legally binding international agreement, whereby all the participating nations commit themselves to tackling the issue of global warming and greenhouse gas emissions. The target agreed upon was an average reduction of 5.2% from 1990 levels by the year 2012.

Wind Energy

Usable as it exists

Inexhaustible

Use where it is available

Reduces our dependency on our natural security

  • Have to be procured & made usable through laborious & environmentally damaging process
  • Limited in reserves, expected to be exhausted in coming 60 years
  • Transportation required, for further processing exposing environment to danger
  • Has Geo-Political implications resulting in over-reliance on our energy security
why wind energy
Why Wind Energy ?
  • Most viable & largest renewable energy resource
  • Plentiful power source
  • Widely distributed & clean
  • Can get started with as small as 100-200 W
  • Produces no green house gas emissions
  • Low gestation period
  • No raw materials & fuels required
  • No pollution
  • No hassles of disposal of waste
  • Quick returns
  • Good alternative for conventional power plants
wind power in india
Wind Power In India
  • The development of wind power in India began in the 1990s, and has significantly increased in the last few years. The "Indian Wind Turbine Manufacturers Association (IWTMA)“  has played a leading role in promoting wind energy in India
  • As of November 2008 the installed capacity of wind power in India was 9587.14 MW
  • Wind power accounts for 6% of India's total installed power capacity, and it generates 1.6% of the country's power

  • Excise duty exemption (Notification No. 6/2002-Central Excise andamendments Thereof)
  • 20% additional depreciation under new plant and machinery
  • Under RGGVY scheme 90% subsidy in case of rural electrification through renewable energy.
types of wind turbine
Types of Wind Turbine

Today's wind turbines are much more lightweight than the turbines used on windmills of old. The wind turbine is usually standard in design, consisting of two or more rotor blades. The energy output of a wind turbine is determined largely by the length of the blades, which installers and engineers call "sweep.“

Majorly , there are three types:

  • Large or medium/ small wind turbines
  • Down or Up wind turbines
  • Horizontal or vertical access wind turbines

group introduction
Group Introduction
  • ALTEM formed because of the group’s focus on Renewable Energy
  • Part of the group known in Indian Power Engineering Sector with interest in renewable energy, power distribution & management equipment
  • The Group is a known name in power sector equipments
  • Well equipped with modern infrastructure & well qualified technicians
introduction to altem power
Introduction to ALTEM POWER
  • In collaboration with a major European company for manufacturing of wind turbine generators
  • Research driven to provide good quality ,reliable , durable & cost effective products
  • Core focus on customer service
  • Office connectivity for real time data and faster services
factors for setting up a turbine
Factors for setting up a Turbine
  • Ideal site requirements:

Wind Speed – An annual mean wind speed of 5m/s or greater

Proximity to neighbors - More than 50 mt – 100 mt from the nearest neighbor property. This in effect eliminates many urban environment

Location - Good clear run of open ground without trees or building to the south west, maximizing wind speed & minimizing turbulence.

wind turbine towers as per site conditions
Wind Turbine Towers as per site conditions
  • Small turbine towers - The case of small wind systems (more than a 1KW) is less simple, with several types of towers and different heights and configurations: guyed towers and non-guyed towers, cylindrical/pipe and lattice configurations, etc.
  • Their installation should be done a) far enough of obstructions, and on the top or on windy hill sides: see Wind Turbines Location; b) with enough room to raise and lower the tower for maintenance and stabilization
  • Guyed small cylindrical Towers - Many small wind turbines use narrow pole towers (pipe, tubing) supported by guy wires. It’s a cheap solution, though with some disadvantages: they aren't easy climbable (for inspections or repairs) and require more land than self-supporting towers, due to the guy wires.
  • Non-guyed cylindrical towers - Non-guyed tilt-up/cylindrical towers use pipe or tubing and a self-supporting design. They do not use guy wires and have a small footprint. These towers can include climbing pegs but are a relatively expensive type of tower.
  • Lattice configuration - Lattice towers use welded steel profiles and are a cheap and tested solution. Most lattice towers aren’t guyed, but there are also guyed configurations: three legged lattice structures suspended on all three sides by guy wires. They are usually climbable.
obstacles involved
Obstacles Involved
  • Wind speed at the ground is near zero, and increases with height.
  • A 15m –18m tower will produce between 15%-25% more energy than a 12m tower
  • Buildings, trees and other obstacles increase both surface roughness, slowing the wind down, and cause turbulence, which significantly affects turbine efficiency. This can cause more than a 50% energy loss
  • Dense urban areas suffer from low wind speeds due to high surface roughness. Rooftops additionally suffer from turbulence
how to size a battery bank
How to size a Battery Bank

Battery bank sizing can be one of the more complex and important calculations in your system design. If the battery bank is oversized, you risk not being able to keep it fully charged; if the battery bank is sized too small, you won't be able to run your intended loads for as long as you'd planned.

calculative factors
Calculative Factors

Before tackling the calculations, start by identifying a few key pieces of information:

  • of electricity usage per day
  • Number of Days of Autonomy
  • Depth of Discharge limit
  • Ambient temperature at battery bank
