Application of Smart Grid technology in cloud computing data center

Smart Grid is the latest trend of the development of the world's energy industry, reflecting the social progress, representing the future development of the power grid. It is widely believed that the future grid should have the characteristics of high efficiency, cleanliness, safety, reliability and interaction. Smart grids should be "stronger and smarter". According to the research and summary of the smart grid, smart grid should have the following characteristics: the need for self-healing ability, high reliability, asset optimization management, cost-effective, user-friendly interaction with the user, compatible with a large number of distributed power access.


　　


Smart Grid As the future of power grid development vision, its own inevitable to the development of technology has guidance and leading role, its technology involves the power system of hair, transmission, change, distribution, electricity and so on. For the cloud computing data room of the planning and design, and related to the main distribution and electricity should be two aspects. Can the power distribution and power technology of the smart grid be used in the planning and design of cloud computing data room to achieve a more optimized cloud computing data center room?


　　


the application of new power distribution technology in smart grid


　　


Future power Distribution technology must have the following characteristics: Network fast self-healing, strong anti-interference ability, provide high-quality electricity, and user interaction. These smart grid power distribution technology will promote the cloud computing data room of the power system more secure and reliable.


　　


1, synchronous break off technology


　　


Cloud Computing Data Center room, due to the large demand for electricity, often involves high-voltage power supply. At present, most of the high-voltage switches are mechanical switches, long break time, large dispersion. This slow process of mechanical breaking can easily cause the operation of over-voltage, speed up the aging equipment or directly damage the equipment. Synchronous break off, also known as intelligent switch, is the voltage or current specified phase of the circuit to complete the disconnection or closure. The use of electronic switch to replace mechanical switch, in theory, the use of synchronous break-off technology can completely avoid the power system operating overvoltage. In this way, the insulation level of power equipment determined by the operating overvoltage can be greatly reduced, and the damage caused by the operation of the equipment (including the circuit breaker itself) can be significantly reduced.


　　


2, fault current limiting technology


　　


Due to the size of the cloud Computing data center, the electricity current in the data center is very large, short-circuit current is also increasing trend, if not to take effective measures to restrain short-circuit current, once the short-circuit fault, switch and user equipment will be unbearable. With the development of power electronic technology and superconducting technology, it is possible to limit short-circuit current, which relies on the development and development of fault current limiter (FAULTCURRENTLIMITER,FCL). There are more researches on superconducting FCL and power electronic FLC abroad, which can be used for reference in cloud computing data center.


　　


3, Active distribution network technology


　　


Future "Active distribution Network" may take the form of similar to the Internet, namely distributed decision and bidirectional trend. Control devices will be available on all nodes throughout the system. The function of the active distribution network is to connect the power supply and the user's requirement effectively, allowing both sides to decide how to run the best in real time. To meet this requirement, the level of control is much higher than the current distribution network level. This includes power flow assessment, competitive voltage control and protection technology, and a new communication control system with more sensors and automatic devices than the current distribution network, which enables the active warning, load balancing and three phase equilibria of the cloud Computing data center. 12 Next Page
