A few years ago, in the IT session, DIY can be a very popular word, DIY Do It Yourself is short, that means DIY. It is just the beginning of the field in IT, DIY assemble their own computer, DIYer who is assembling a computer.

We introduced earlier, the computer is composed of many parts, more or less in between these parts there were all kinds of relations, such as interfaces to be consistent, Sudu to coordination, and if the parts properly selected, not only affect your computer’s Read More…

In industry, social activities and daily life power energy is essential mainly to supply through the grid. So far most of the power grid operated by power companies, and in compliance with the premise of many of the provisions also provide stable power. However, competition principles and rules relaxed, fuel cells as electric power has been given a new space. Content of its rules relaxed: ? grid divided into generation, transmission and distribution parts; ? power sector is divided into several companies, introduce competition; ? user can direct contract with the power companies buy and sell electricity; ? allow sale of small-scale decentralized power generation power. Lenovo Thinkpad X300 battery Incidentally, the greatest impact for the fuel cells that can be freely traded to the power companies generating excess electricity.

(1) operations

To make fuel cells more penetration into society, the most important thing is to use more affordable. In the current conditions, the fuel cell’s equipment costs are still relatively high, so they need much longer time for the rated operation to improve efficiency. If a long operation, then through the sale of surplus power generation power grid power system becomes more important. Electricity and power generation power grid power can be traded, can make the economics of fuel cells are dramatically improved. This will load a small family is particularly important, Toshiba Satellite M100 battery however, deal only if the power generation in fuel cells where strong introduction to the power grid would cause a great burden.

(2) configuration

View from the fuel cell’s capacity, often connected to the electricity network with the system as power distribution system. Connected fuel cell power distribution system that has the following advantages. ? is set to power a fuel cell power generation directly connected with adjacent users can reduce the supply of electricity from the power grid, power distribution system capacity can be maintained above the maximum demand; ? As the distribution line current reduction in distribution system losses reduced accordingly; ? fuel cells can improve the distribution system voltage control of voltage stability; ? If you can link to the online distribution of accidents, can improve reliability.

If the maximum of utilizing these configuration, then make use of natural energy dispersion type power supply with stable capacity.

Many new services such as quality of electricity supply

The power grid after deregulation according to the user’s need to provide multiple services. For example, the domestic electricity supply, the short outage for a few minutes what the impact will not refrigerators and heating machines and other equipment and even a moment of power failure would have serious implications for the information equipment can be considered separately on their own to change the supply of power quality power. Sony VGP-BPS3 battery In addition, you can study according to the needs of users to select service mode to improve the supply of electricity blackouts would not the price, while reducing the power supply to allow short-term price of power failure. One of the means to achieve this purpose is electric power network managers must have its own fuel cells and electric storage devices, to provide and use a variety of quality power.
