for cloud computing data room 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.

4, energy storage technology


Energy storage technology has been regarded as an important part of power grid operation. After introducing the energy storage link in the system, it can effectively realize the demand side management, eliminate the peak and valley difference between day and night, smooth load, not only can use the power equipment more effectively, reduce the power supply cost, but also can be used as a means to improve system running stability, adjusting frequency and compensating load fluctuation


The energy storage technology can be used for the emergency power supply of cloud computing data center, and to make full use of the local peak and valley electricity price difference. The existing energy storage methods can be divided into mechanical storage, chemical energy storage, electromagnetic energy storage and phase change storage energy. Superconducting energy storage can be used as an ideal electromagnetic energy storage device due to its large current, high power density and fast access, and the critical temperature of superconducting materials has been the limiting factor of superconducting energy storage, so the research of direct cooling superconducting energy storage (htc-smes) has been highly valued by the United States and Japan. But most superconducting energy storage devices are cryogenic superconducting energy storage systems.

Future Data center sensors will be more intelligent, the function will gradually merge. Wind, fire, water, electricity, gas, temperature, humidity, smog, carbon dioxide and so on are the Sensor collection object. The sensor not only can analyze and extract the characteristic data of the data center environment, but also can interact with the specific data management analysis system, and can provide the overall analysis and scientific evaluation to the data center's daily data, the overall efficiency and the environment index.


2, advanced electric power monitoring technology


Power monitoring technology is divided into two levels: electric monitoring technology and electricity control technology. The new type of electric monitoring technology is used to monitor the user's power consumption information dynamically, and to help the users to understand their detailed electricity information, so as to instruct the users to optimize the system's electricity behavior. Based on the information acquisition and the user's demand, the new type of electric power control technology automatically controls the power system of the whole data center, and realizes the distribution of electricity more rationally.
