Flywheel energy storage technology for the data center power "insurance"

More and more people are beginning to realize the role of UPS power in the data center. Instantaneous power interruption, the loss of data loss so that companies can not stand. Data show that after the September 11 incident, many enterprises that did not do disaster recovery backup failed overnight without customer information, no transaction amount and no financial records. The loss of enterprise core asset data made it impossible for them to get out of their difficulties. So, how to choose UPS for your data center?

Bear the brunt of reliability. Driving in winter, often encounter this situation, the car was very good the day before the next morning as the weather was too cold, suddenly could not hit the fire. This situation is often a problem with the battery, which is the characteristics of chemical storage. It relies on electrons to generate electricity from the cathode to the anode, but the process is invisible and unpredictable, leaving a hidden danger to reliability and inherently flawed UPS power itself. Currently, there is a new energy storage technology on the market, namely flywheel energy storage technology. Its principle is very simple, rely on the high-speed rotation of the flywheel to generate electricity, power protection for the data center. However, the more simple and reliable. First of all, the flywheel is of good quality, and secondly, the flywheel must generate energy when it rotates. If the mass is constant, it is easily proportional to the square of the speed. Coupled with the monitoring system, through the monitoring of the vertical, horizontal, rotational direction, vibration and speed of the flywheel, users will be reminded promptly when the rotational speed or physical condition changes, so as to ensure the reliable operation of the "flywheel UPS". Therefore, both in practice and theory, the "flywheel UPS" is seven times less likely than the traditional battery UPS reliability or failure probability. For the data center users undoubtedly increased insurance, equivalent to buying a "full risk."

Second, you need to consider the price. When many users buy products, more consideration is the initial cost, while ignoring its subsequent expenses. In fact, with rising energy prices, electricity is increasingly becoming a more expensive resource than a product, much like the difference between a popular bulb and a LED lamp. Flywheel UPS power supply efficiency is 98%, the traditional battery UPS is about 92% -93%, which means that the loss of flywheel UPS only 2%, while the traditional UPS is about 8%, flywheel UPS energy saving than traditional UPS 75% . Data show that UPS in the entire data center energy consumption accounted for about 15% -25% ratio. Calculated from the above data, relying solely on the "flywheel UPS" can reduce consumption of 10% or more. For large data centers, the potential savings in one year can reach several million kWh, a significant expense for data center operators. Data center life expectancy is 10-20 years, from the point of view of the entire life cycle cost, the initial cost of equipment only a small percentage, if we follow the 10 or 20 years of data center life cycle point of view, but rather "Flywheel UPS" Can help users save up to 60% of the cost.

Finally, the natural services to consider, including the length of insurance, responsiveness, and more. The traditional battery life is generally 3-5 years need to be replaced, usually have its charge and discharge, once the charge-discharge operation is wrong, will greatly affect the battery life. At the same time, but also to ensure that the battery runs at a constant temperature, too high or too low will also affect the battery life. Batteries due to improper operation, or temperature changes occur frequently happen in the case of the flywheel, you may not need to do so. Flywheel UPS can operate normally between 0 degrees -40 degrees Celsius, ensuring 24 × 7 × 365 uninterrupted operation, its life expectancy is up to 20 years, basically can meet the needs of the data center. At the same time, flywheel maintenance is very simple, only need to replace the bearing once every three years, the product's stability and reliability, as well as the ease of operation, greatly reducing the cost of maintenance. In the absence of risk or the probability of occurrence of less risk, the quality of service is also guaranteed.
