CHAPTER 1 INTRODUCTION World is moving towards the greener sources of energy to make the planet pollution free and environment friendly. The major utilization of these sources with grid integration is the challenging task. It is therefore Distribution Generation particularly single phase rooftop Photo Voltaic system are major research area for grid integration, since these sources have huge opportunity of generation near load terminal. The rooftop application involving single phase Distribution Generation’s fed with Photo Voltaic source can be not only utilized for household use but the excess energy can be transferred to the grid through proper control scheme and adequate hardware. Photo Voltaic systems can generate high voltages. Safety is therefore very important in order to avoid accidents and damage of expensive components and equipment. For safety reasons, solar arrays are normally earthed, either by placing a matrix of metal in the ground under the array, or by using conventional earth rods. It is normally not necessary to protect solar array from direct lightning strikes, provided that their mounting structure is well earthed. However, inverters or other electronics controls connected to the array should be protected. Blocking diodes are installed in solar arrays to prevent reverse current flows into …show more content…
A storage battery is a reservoir, which may be used repeatedly for storing energy. Energy is charged and drained from the reservoir in the form of electricity, but it is stored as chemical energy. The most common storage battery is the lead-acid battery that is widely used in automobiles. They represent about 60% of all batteries sold worldwide and are usually more economical and have a high tolerance for abuse. Lead-acid batteries are inexpensive, relatively safe and easily recyclable, but have a low energy-to-weight ratio, which is a serious limitation when trying to build lightweight
Explain why the circuits works? It converts AC voltage to DC voltage. Current flows through the diode in one direction, showing only the positive half-wave on the oscilloscope. The negative half-wave is suppressed, while the positive half-wave appears across the load.
There so much static electricity that it could short telephone wires, make barbed wire fences catch on fire, and literally make cars start to melt. It's like putting
A solar panel can be used for many things, but the biggest thing is used for capturing the sun's energy in order to make it useful provide energy to the house, buildings even be sold back to the city or town you live in etc.. It works by collecting the sunlight throughout the day, then converts into energy that's usable, then the electricity travels to the net meter then the energy is used for anything. When having the solar panel on a roof you can use it for personal use or even sell it back to the electrical company and they’ll pay you. There are about 73,000 terawatts of energy shining down that's 10,000 times then what we use on daily bases. Perks of having solar panels it's a tax 30% tax write off, doesn’t need any fuel combustion, Securing your energy and not depending on National
In this assignment I was responsible for conducting a study to better understand the impact of lightning on our overhead transmission lines. I has tasked with creating geometric models using EPRI (Electronic Power Research Institute) software and analyzing the affects of lightning on the transmission lines. This rotation helped me develop my analytical, presentation and technical skills. For my second rotation, I was a Supervisor with the Protective Systems Testing department in Substation Operations. I supervised relay protection technicians in the testing of protective relays across twenty-eight substations in Manhattan.
Recent years show that most solar electric energy products have dropped in price and have been useful to many others because of

But what should you do when the skies open up and wreak havoc on your residence or business? Even if the strike hits next to it, the voltage
will sponsor the research of Jeff Dahn till the issues are resolved. Mr. Dahn will focus on expanding the capacity of voltage in batteries without damaging their longevity and reducing the cost of materials. Based on the chief technologist in Tesla Motors Mr. Straubel’s expectation energy density of the batteries and cruising range of electric vehicles need to be increased, thereby battery cost and weight need to be reduced in order to cut the price for Tesla car further model and to meet a sales target of a cumulative one million vehicles by 2020. “In addition to advances in chemistry, Tesla Motors is aiming to reduce its battery costs by bringing in-house the suppliers and processing of lithium, nickel cobalt and graphite. We are making constant progress on all that.
In other words, this system could save your life. Specifically, the battery has its own safety management systems that monitor the activity of each cell and process the information to a CPU (Central Processing Unit). The CPU can do many amazing things like adjusting the cooling system, warn the driver or even forcefully stop the battery from
Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.
“Renewable energy resources that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun or from other natural movement and mechanisms of the environment. Renewable energy does not include energy resources derived from fossil fuels, waste product from fossil sources, or waste products from inorganic sources.” There are a few types of renewable energy sources. 1) Wind Energy 2) Biomass 3)
wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources
Smart grid technology has been employed by two-way communication introduced for controlling the use of appliances by However, the widespread presence of Internet access in most homes has made the smart grid more practically reliable to implement. Smart grid is equally advantageous for
In the modern age of technology, the abundance of batteries cannot easily be overlooked. Batteries convert chemical energy into electrical energy and power several electronic devices such as cell phones, laptops, tablets, PDAs, and iPods to name a few. Furthermore, they provide power to households and several industrial enterprises around the world. Indeed, these batteries have become very advantageous to people because of the convenience they provide in everyday encounters. However, batteries can also be harmful despite the advantages they offer.
The auto battery is the thing that powers all the electrical parts of the auto. It is normally a rechargeable 12 volt lead-corrosive battery that powers the electrical framework in the vehicle. This implies there are different chemicals in the battery that goes into a response when it is being used. When it is energizing, the concoction responses are turned around. Auto Battery Components The fundamental segments of the auto battery is that it begins the starter engine and the start framework.
