Project Summary

The prospective growth in necessity and protection of the natural environment dictating the global warming compels to rise the expansion of renewable energy. In the renewable energy sources wind energy is plenty in nature, as a consequence expansion of wind energy ruled net renewable power generation capacity. The renewable energy resources are cost effective and viable energy resource due to this advantage the rooftop wind energy system is proposed for commercial and residential areas. The machines used for wind power generation in this project is “Rooftop Wind Energy Conversion System”. Designing a cost-effective wind power generators are a great matter of interest nowadays. Generator size and complexity reduction with low-speed operation is desired objective. The generator that will be investigated for “Rooftop Wind Energy Conversion system” has flux switching perspective and a dual stator along with single rotor. In contrast with PM machines, Dual stator generator are of low cost and reliable, but PM machines are costly, and the permanent magnets are rare earth magnets and demagnetizes with time. The same perspective of flux switching is obtained in this machine with dual stator, and each stator has AC and DC windings. The rotor of this machine is very simple and robust. The power density of this generator is high and have high output power due to dual stator mechanism.       

Project Objectives

Following are the main objectives of the proposed Project.

?   To design the dual stator flux switching generator for Rooftop Wind Energy Conversion System targeting the residential and commercial areas.

?   To investigate the Phase Flux, Phase Voltage and torque and power characteristics and optimize the generator for maximum performance.

?    Integration of rooftop wind energy conversion system with main grid and DC micro grid.

? To fabricate proposed Dual-stator Field Excited flux switching generator and analyze machine performances experimentally.

By accomplishing the above-mentioned objectives, the manufacturing cost of Dual-stator Field Excited flux switching generator is reduced as compared to PM machines.

Project Implementation Method

The implementation of our project consists of the following two parts.

1) Simulation

2)  Hardware

Simulation:

                  For the simulation purpose the registered version 20.1 of JMAG software is used to analyze the performance. In JMAG the proposed generator will be designed which is composed of two stators, with DC and AC windings. Results obtained from the proposed generator by the JMAG will be compared with the existing conventional state of the art. 

Hardware:

In the next step hardware for Rooftop Conversion Energy System will be designed. It consists of following major parts.

Generator Fabrication:

Inner Stator

Outer Stator

Rotor

Copper wires

Assembly parts

Rooftop Installation:

                                     To install the rooftop mechanism, the micro wind turbine is placed at the roof of any building, residential or commercial. The wind energy is extracted form this turbine and is given to the generator.   

Benefits of the Project

Wind Energy is a potential renewable energy resource to cope up with ever increasing energy demands in future. Designing a cost-effective wind power generators are a great matter of interest nowadays. Generator size and complexity reduction with low-speed operation is a desired objective. Generator’s Output Voltage enhancement and Loss minimization in wind power generators are also required. In this project Rooftop Conversion Energy System is designed to achieve low-cost and improve output power. Due to the flux switching perspective the machine is brushless and does not have slip rings, by which the maintenance cost is also reduced.  This generator is designed for the availability of the low-cost renewable energy at domestic level up to 1kw and requires less annual maintenance. 

Technical Details of Final Deliverable

1. Generator for Rooftop Conversion Energy System has Low cost due to no magnet usage because it is rare earth material.
2.  Flux controllability due to field excitation winding.
3.  Brushless operation due to elimination of slips rings.
4. 1kw rooftop energy conversion system for domestic purposes.
