IMPACT OF WIND ENERGY CONVERSION SYSTEMS FOR DISTRIBUTED GENERATION By, Shikha T.S,Bhatti and D.P.Kothari

This novel work : 1. Introduces a new concept of amplifying the wind speed before it comes in contact with the rotor blades of a savonius turbine by using a convergent nozzle. 2. Emphasizes on the improvement of the efficiency these commercially unsuccessful rotors. 3. Verifies the nozzles characteristics with the help of a research program involving wind tunnel tests of five different models. 4. Analyses the important nozzle dimensions

DISTRIBUTED GENERATION – A TURN FOR THE BETTER Distributed resources are: 1. Uniquely portable, flexible, diversifiable, controllable, and accountable to end-users. 2. Avoid many of the hidden costs of centralisation and entail less risk. 3. Enable utilities to increase capacity in small increments.

New modified rotor can be conveniently built in small units (Distributed generation) 4. Reduce delivery costs and make more efficients use of existing grid. 5. Avoid T and D losses and risk of failure. 6. Lower technical risks and increase reliability. 7. Entail environmental and social benefits.

UNSUCCESFUL BUT PROMISING - SAVONIUS WIND TURBINE Principle of operation: A simple savonius turbine

Required modifications: Use of concentrating nozzle with savonius rotor in two different positions

A four bladed savonius rotor with a convergent nozzle A six bladed savonius rotor with a convergent nozzle

IMPORTANT NOZZLE PARAMETERS 1. Length of nozzle (L,cms) 2. Outlet to inlet area ratio (A 2 /A 1, Ratio ) Experimental set up: Five nozzle models (Different outlet area ) fabricated and tested outside wind tunnel in following conditions: 1. controlled wind velocity at the inlet of the nozzle.

. 2. outlet of nozzle left open to the atmosphere. 3. Tests conducted for three different lengths of the nozzle. 4. Nozzle placed at different distances from the wind tunnel outlet.

RESULTS Table: Average amplification of wind velocity for different models Model no. A 2 /A 1 (Ratio) L = 80 cms L = 55 cms L = 25 cms

ANALYSIS OF PERFORMANCE CHARACTERISTICS Area versus velocity ratio

CONCLUSION 1. The six-bladed rotor turns out to have an optimum design. 2. Use of nozzles with six-bladed rotor enhances the power extraction at low wind speeds. 3. The new improved rotor using a convergent nozzle can outperform existing ones by a significant margin.

4. The amplification rate thus also becomes constant after a fixed distance from the wind tunnel. 5. Calculations indicate that this rotor will draw 2 to 3 times as much wind as conventional windmill of same swept area. 6. The ideal power coefficient and hence efficiency can be enhanced to a good extent.
