Uninterruptible Power Supply – Electricity Generation & Distribution

To fully understand and appreciate the importance of uninterruptible power supplies (UPS), it is crucial to first understand how electricity is generated and distributed in whatever country around the world you happen to be. In many Westernised societies it is tightly controlled, regulated and fairly reliable but in other areas it is not and power protection at the final point of consumption, whether business or residential, needs to bare this in mind. It may be that what’s needed is some form of micro-generation as well as uninterruptible power supply. Electricity can be derived from a number of sources these days and the call for renewable technology in response to environmental pressures means the list is getting longer. Coal, gas-fired or nuclear generation stations have been the primary methods so far but wind, wave or solar power are beginning to make their mark. The phenomenon that generates electricity is termed Electro-magnetic Induction. Its output is an alternating current (ac) waveform. The process by which this happens utilises magnets on a shaft which rotate near to windings (usually three) into which electric current is induced; referred to as Electro-motive Force. The process is the same in each case; the only difference between each of the energy generation types is the fuel it uses to make the shaft spin. The windings within a generator are separated by 120 degrees of rotation, which creates a three-phase waveform comprising of P1 (phase 1), P2 (phase 2) and P3 (phase 3) components. The measurement of kV, at which electricity is generated, varies around the world from country to country, region to region. In the UK, for example, it is typically 25kV, which is stepped up to 275/400kV before being distributed as a three-phase, 50Hz supply. It needs to be distributed at a high voltage to overcome resistance (that might be in the network) or transmission losses. As it moves through the network, however, to the point of use, the voltage is reduced. On the outskirts of major towns and cities, substations lower the voltage. In the UK this would be to 132kV. These substations are connected to even smaller substations that reduce the voltage even further to typically 33kV and 11kV (UK). These are found either within or close to the point of delivery. It is at these substations that a neutral and earth reference are added so that, in the case of the UK, a 400Vac, three-phase, plus neutral and earth (TP+N+E) can be supplied to the incomer of a site or building, which could be residential (larger buildings such as blocks of flats), commercial or industrial. The physical point at which this happens is known as the Point of Common Coupling (PCC). In the UK, a single-phase, 230Vac supply (more typically for residential consumer use) can be derived from the same substation (or incomer), by drawing on any one phase and neutral. In this way, the earth and neutral reference points are connected all the way back along the distribution network to the substation. Each country or region around the world has its own set of grid transmission and distribution codes that govern electricity generation and distribution. In particular these stipulate minimum and maximum voltage and frequency values allowed. For any site, the quality of power received through its incomer is directly affected by the performance of the electrical distribution network upstream. Today this can be intercontinental and span a range of political and cultural environments. Within a distribution network power problems can be caused by:? Network operation, grid switching, auto re-closers and fault tracing. Network hardware failure, including transformer and breaker malfunctions. Power shortages during peak demand periods when supply is restricted. Accidental severing of supply cables during construction or street works. Acts of terrorism, vandalism or deliberate sabotage. Environmental activities such as lightning, heat, rain, snow, ice, wind or wildlife. ? On any site, a stable and clean electricity supply can be affected and influenced by local overloading, simple switchgear faults and the operation of industrial or commercial equipment and fittings – including mechanical presses, welding equipment, lifts, escalators, air-conditioners, photocopiers and fluorescent lights. All of these can induce power problems into a mains power supply that may have been reasonably stable and clean beforehand. A review of power generation and distributed and the effect it might have on power quality (alongside other environmental, political and social unrest that may have an effect) has a baring on the size and type of uninterruptible power supply that may be ideally suitable to an installation.

Peak Oil: Does America Have Sustainable Power?

Peak Oil: Does America Have Sustainable Power?

We are living in a tumultuous world. We are experiencing an economic downturn, and the way things look right now, it seems this ?recession? may even be greater than the great depression. The war as they say is the cause. The budget deficit for 2008 was over $400,000,000. This money certainly would have been put to better use within America itself.

The ?Conspiracy? Theory

Most people will are of the opinion that the president of the United States waged war on Iraq country due to oil; America after all is one of the world?s largest consumer of this scarce natural resource. Everything in the US is automated, or electrical. To run machines you need oil products, to produce high demands of electricity you need millions of barrels of oil to run the generators.

It is not preposterous to believe that the U.S, whose reliance on Middle Eastern oil is immense, has vested interest in acquiring a country so rich in black gold. First of all it will make oil sources available anytime they want without having to bother with diplomacy and pass through another government. Second more profit for the American oil corporations, because if they can get fossil fuel at cost then they will have more earnings. The theory makes sense and could very much be possible.

Sustainable Power Resources

We are not here to discuss political and personal issues. All I want to do is to point out that there are other faces in this picture. Yes, America is one of the world?s largest energy consumers, but it also has the largest alternative energy resources in the World.

Geothermal, Hydro, Wind and etc

The United States of America is considered as the world?s greatest geothermal energy producer. The Geysers located just north of San Francisco are the planet?s first and largest dry steam fields. The amazing thing about these power plants -since there are several- is that sewage waste from surrounding cities are pumped into the geothermal plant in order to replenish the supply of steam needed for energy production. States such as Nevada, Oregon, Idaho, Arizona, and Utah have their own geothermal plants.

Considered the fourth country with the largest hydropower capacity, the U.S has revolutionized hydropower by building numerous dams in highly planned areas all across the country. Definitely, the most popular is the Hoover Dam. At the time it was fully operational Hoover Dam was said to be the world?s largest electricity generating hydropower plant. The Hoover dam supplies electricity to the states of Nevada, Arizona and most of Southern California.

Rock Port, Missouri is a city in North America which is fully powered by wind farms. Of the 50 states in America, over half have wind farms which help supply their electricity needs. Some states may have aesthetic issues, but wind farms will definitely become essential in the future especially when the impact of declining oil supplies from the Middle East is felt.

Conclusion

The United States have their own oil resources right within their backyards. There are new and promising sites in Texas and just off shore from New Orleans. And then there is a lot of excitement around the ?Bakken Formation? in the States of Montana and the Dakotas. But one thing remains obvious, fossil fuel as an energy source is not viable for human health and the future of our environment. If you?re still asking why the American government is waging war for oil? Maybe it?s not just oil after all. Perhaps, there is a more deeper and nefarious plan at work, a peace crusade with a sword in hand, but not to accomplish peace, rather to expand power and?
