The Generation of Electricity Using Tidal Power EEE Report is also explaining the c categories of tidal power; Tidal power can be classified into three main types that are Tidal stream generator, Tidal barrage and Dynamic tidal power.

These days our very actions and consumer power is hurting our planet Earth. Pollution, smog, littering, and most notably of recent times to emerge is the threat of Global Warming. Remarkably society has shifted in attitude, with actions and research being conducted to clean the mess created. The frontrunner idea on how we can have a cleaner future is based on how we harvest our energy. Engineers are looking into Wind, Solar, Nuclear, and Hydro power. The technology around these is still developing and is unpredictable with some having hazardous effects. A smart choice may be Tidal Power.

•           Tidal stream systems make use of the kinetic energy of moving water to power turbines, in a similar way to windmills that use moving air. This method is gaining in popularity because of the lower cost and lower ecological impact compared to barrages.

•           Barrages make use of the potential energy in the difference in height (or head) between high and low tides. Barrages are essentially dams across the full width of a tidal estuary, and suffer from very high civil infrastructure costs, a worldwide shortage of viable sites, and environmental issues.

•           Dynamic tidal power exploits a combination of potential and kinetic energy: by constructing long dams of 30–50 km in length from the coast straight out into the sea or ocean, without enclosing an area.

Conclusion:

In conclusion, Tidal energy has the potential to be a leading energy source with the right leadership. Comparing the two systems, Tidal Stream is more of a wise choice than Tidal Barrage. The new major projects to be built for the next 20 years around the world will be the key test.

Project Report On Flexibleac Transmission Systems (Facts): The philosophy of FACTS (Flexible AC Transmission Systems) is used to control electronic devices to be used for the flow of energy in the public transport network control at full capacity. FACTS are one of the best ways to reduce the need for construction of new over head transmission lines is to increase power flow over existing lines.

Without electricity, modern society would cease to function. As the volume of power transmitted and distributed increases, so do the requirements for a high quality and reliable supply. At the same time, rising costs and growing environmental concerns make the process of building new power transmission and distribution lines increasingly complicated and time-consuming. Making exciting lines as well as new ones more efficient and economical then become a compelling alternative.

The definition of FACTS is defined by ‘IEEE’ as power electronic based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and power transfer capability.

The benefits of the Flexibleac Transmission Systems (FACTS) are as follows:

• A Rapidly Implemented Installations

• Increased System Capacity

• Enhanced System Reliability

• Improved System Controllability

• Seamless System Interconnections.

Project Report On Flexibleac Transmission Systems (Facts) Conclusion:

It is envisaged that in future FACTS devices could be installed on wide scale by electrical utilities in an attempt to control the power flows through their networks. Concern has been expressed that such wide scale application of FACTS devices could cause conflict between the control systems of the different devices Using the advanced solid state technology, FACTS controllers offer flexibility of system operation fast and reliable control. They better utilization of existing power generation and transmission facilities without comprising system availability and security .The planner has to select controller out of the set of FACTS controllers, for improving the system operation based on cost benefit analysis.

This Flexible Display EEE Project Report focuses on ecological and economic aspects of the flexible display along with some technical aspects and applications. The basic operation of the display is discussed, and some of its main implementations, and parallel developments. The core of the problem is an analysis of economic and environmental impacts of the above applications.

A durable and flexible display with low power consumption, high contrast, a technical challenge for years. They have robust compliance by low weight, and in some cases, portable, rollable and unbreakable. The recent successful integration of flexible display technologies and the traditional web-based processing and / or inkjet technology offers the possibility of inexpensive and high-throughput roll-to roll production opened and showed the potential to replace the paper today.

The advantages of flexible display are as follows:

•Much faster response time,

•Consumes significantly less energy

• Able to display “true black” picture.

• Wider viewing angles.

•Thinner display.

•Better contrast ratio.

•Safer for the environment.

• Has potential to be mass produced inexpensively.

The disadvantages of flexible display are as follows:

•Constraints with life span.

•Easily damaged by water.

•Limited market availability.

Conclusion:

Because the components and manufacturing processes mature flexible electronics, the concept of flexible flat panel display is finally a reality. Flexible displays offer tremendous advantages over conventional flat panel displays, such as low weight, durability, low power consumption, mobility, etc. In particular, OLED displays offer bright sharp images at wide viewing angles and bright light are, however, difficult to encapsulate.

Gyricon and electro phoretic displays have thin form factors and can be viewed at a great range of angels, but their high resolution displays still require development. LCD displays are already mature, but making the sandwich-structured device flexible is still challenging. Once technical difficulties are overcome and roll to roll processing becomes feasible, flexible flat panel displays will widely commercialize and enter.

The Project Report On Energy Saving Through Counter is about Energy saving through counter. Most of the energy we use today comes from coal, oil, and natural gas. They are fossil fuels. They take millions of years to form. We can’t make more quickly. They are non renewable. We need to save energy. A good way to save energy is by not wasting things. Don’t use paper plates or cups all the time. You only use them once and then throw them away. Write on both sides of your paper. Use a lunch box and thermos instead of paper bags and box drinks.

Present project is designed using AT89S52 microcontroller to count the number of person present in the room and to save the energy used by the appliances. The project utilizes the IL74 optocoupler which is used to detect the visitors. If a person enters in the room then optocoupler will detect the person and the buzzer will generate a sound and there will be an increment in the number of person on the LCD. LCD used in our project is JHD162A which is used to display the number of person. If a person leaves the room then optocoupler will detect the person and buzzer will generate a sound and there will be a decrement in the number of person. On the basis of number of person, different appliances like bulbs, fans, A.C., T.V. etc. can be switched on/off automatically by using relays. A relay is an electrically controllable switch. It allows the isolation of two separate sections of a system with two different voltage sources. Relay used in our project is electromagnetic relay.

 Project Report On Energy Saving Through Counter Conclusion:

In conclusion we can say that, when there will be no person in the room then no device will work. Devices will work only on basis of no. of person present in the room. Thus, this project not only counts the no. of person, it also saves the energy used by the appliances.

This Btech Final Year EEE Project Report on Energy Efficient Electrical Drives discusses topics on energy efficient electrical drives, the electric drive can be made efficient and ultimately save the electric power. Which affects the economical aspects of the unit and so the industry which using these drives. So by using these efficient drives we can save the energy and also the money which is in terms of the electric bill. The key challenges to increased efficiency in systems driven by electrical machines lie in three areas: firstly, to extend the application areas of variable-speed electric drives through reduction of power electronic and control costs: secondly, to integrate the drive and the driven load to maximize system efficiency: finally, to increase the efficiency of the electrical drive itself.

An electric drive is to convert as a form of mechanical equipment to the electrical energy into mechanical energy and provide electrical control of these processes. The used for motion control, defined as an electric drive. Drive system that the motor and speed control devices belong. Drives will be widely used in industry, where variable speed is required. Since energy must be used with maximum efficiency, because the power consumed by the drive must be at least in the economic performance of industry. Energy-efficient drives are defined as the drives which have maximum efficiency.

Conclusion:

There is a trend for increasing efficiency within the electrical machine itself, but the greatest gains are at system level when the machine is combined with a power electronic converter to create a variable-speed drive. The main barriers to this lie in the initial cost of a variable-speed drive, even though in many cases the payback period is short. Future advances in technology will reduce the capital cost of the drive, and so existing markets will grow and new markets open up. In the future, electric drives will become integral to the propulsion of road transport vehicles, so the need for maximizing their efficiency will become even more pressing than it is today.

This Electrostatic Micro Power Generator from Low Frequency Vibration Such As Human Motion describes the analysis, simulation and testing of a micro engineered motion-driven power generator, suitable for application in sensors within or worn on the human body. Micro-generators capable of powering sensors have previously been reported, but these have required high frequency mechanical vibrations to excite a resonant structure. However, body-driven movements are slow and irregular, with large displacements, and hence do not effectively couple energy into such generators. The device presented here uses an alternative, non-resonant operating mode. Analysis of this generator shows its potential for the application considered, and shows the possibility to optimise the design for particular conditions. An experimental prototype based on a variable parallel-plate capacitor operating in constant charge mode is described which confirms the analysis and simulation models. This prototype, when precharged to 30 V, develops an output voltage of 250 V, corresponding to 0.3 muJ per cycle. The experimental test procedure and the instrumentation are also described.

Energy harvesting micro-generators provide alternative sources of energy for many technical and personal applications. Since the power delivered by such miniaturized devices is limited they need to be optimized and adapted to the application. The associated electronics not only has to operate at very low voltages and use little power it also needs to be adaptive to the fluctuating harvesting conditions. A joint development and optimization of transducer and electronics is essential for improved efficiency.

Conclusion:

An electrostatic micro power generator for low frequency energy harvesting applications. This generator shows 40+W of power output at very low frequency vibration (2Hz). Technologies we developed are: 1) a micro power generator consisting of micro ball bearings to roll with the separation gap control and to keep separation gap constant, and 2) a new electric structure to accommodate miniaturization. The advantage of our design is the high power generation structure of both the controlled gap between electrodes and long-range moving, and the high surface potential electrets structure.

This BE EEE Project Report On Construction Of Transformer describes the principle and construction of transformer in brief. All parts in transformer are explained like Bushings, Conservator tank, Breather, etc. Transformer is a device used to convert electrical energy from one circuit to another circuit without changing the frequency. This process goes by inductively coupled circuits, which are the coils of the transformer. It consists of two coils, primary and secondary coil.

In Principle of Transformer the report discussed about primary coil and secondary circuit and its works. The transformer is based on two principles: first, that an electric current can produce a magnetic field (electromagnetism), and second that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromagnetic induction). Changing the current in the primary coil changes the magnetic flux that is developed. The changing magnetic flux induces a voltage in the secondary coil. The report also explains the details about the construction of transformer along with the main parts which are used in construction. The main parts of transformer are

1. Core construction. 2. Windings. 3. Bushings. 4. Transformer tank. 5. Conservator tank.                            6. Breather. 7.     Buchholz relay.

A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors called transformer’s coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer’s core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF), or “voltage”, in the secondary winding. This effect is called mutual induction.

 BE EEE Project Report On Construction Of Transformer Conclusion:

Mainly we use the step up transformer in the power stations and the step down transformers are used in sub stations, distribution stations.  We can design the transformer by using the above points. Each point is briefly explained in the above points. These are the constructional features of the transformer and the main points in the design of the transformer.
