Perhaps nobody knows that the originator of UPS power is a flywheel device. However, due to its large size, unstable operation and other factors, it was gradually replaced by lead storage battery UPS. Today, the Flywheel UPS is making a comeback and it has begun to emerge in various fields. So, what is the difference between flywheel UPS and traditional power supply?
Taking the most popular flywheel UPS on the market for example, it is manufactured by the American ACTIVE POWER company. Its principle is very simple, similar to the "mechanical watch" is through the high-speed rotation of the flywheel, the mechanical energy is converted into electrical energy, using mechanical energy storage to replace the traditional chemical battery energy storage. What are its characteristics and advantages?
First of all, the efficiency of the flywheel UPS is very high, up to 98%. That is to say that only 2% of the loss is consumed by electricity. When the load is 50%, the efficiency can still reach 96%, which greatly exceeds the efficiency of traditional battery UPS. Under normal circumstances, the conventional UPS has a power supply efficiency of only 92% under full load. In other words, the flywheel UPS saves 75% compared to traditional UPS. For a 10 megawatt data center, the electricity savings in a year can reach millions of kWh, which is not a small amount.
Second, flywheel ups are more secure and reliable. The principle of flywheel UPS is very simple, however, this world is often the case, the simpler and more reliable, Avenue to Jane is the truth. The flywheel is of mass, and there is speed in rotation. If the mass is constant, it is proportional to the square of the speed. The energy generated by the speed can be easily calculated by the physical formula. It is fine and measurable. It is completely different for chemical energy storage. It generates electricity from the cathode to the anode by electrons, but this process is not visible or measurable. There may be voltage when measuring with equipment, but it may not be able to provide so much energy when it is actually discharged. . The most common example is driving in the winter. It was a good day to drive. The next morning, it was impossible to get a fire. It was definitely a battery to check. This is a characteristic of the chemical reaction. According to statistics, 70% of UPS faults are caused by batteries, which have become the most unreliable component of traditional UPS systems. "Flywheel UPS" is seven times less reliable than traditional battery UPS reliability or the probability of failure.
Third, the flywheel UPS has a low degree of reliance on the environment and does not require air conditioning and cooling. Its operating temperature is between 0 and 40 degrees, which is a very large savings for the data center. Because the working temperature of the traditional chemical battery is between 20 and 25, when the room temperature exceeds 25 degrees, the battery life will be shortened by one year. The battery life must be shortened by one year. Air conditioning and cooling must be used. According to statistics, the consumption of air conditioning Electricity already accounts for nearly one-third of data center electricity charges.
Fourth, the requirements for land occupied by flywheel UPS have been greatly reduced. Up to 75% savings for users. Today, land has become the most critical resource. Its significance is self-evident. For example, for 20,000 or even 50,000 square meters, the battery covers an area of ​​1,000 square meters. This is still a backup time of 15 to 30 minutes. If the backup time reaches 30 to 60 minutes, there must be 2000 even more space. Such a large space brings customers additional construction costs, a lot of air conditioning and refrigeration costs, including the entire maintenance cost.
Fifth, the flywheel UPS is green. ActivePower flywheel UPS itself is a steel flywheel and has a life span of 20 years and is non-toxic. A button cell can contaminate a square kilometer of land. Lead dust produced in the production process is also very frightening, it is reported that 1,000 batteries will produce 63.2 kg of lead dust. These fumes can affect the surrounding air, soil and rivers. The direct consequence is that lead poisoning occurs when the content of lead in the blood is too high. It can cause a series of abnormal manifestations of the nervous system, blood system, and digestive system of the body. It can even seriously endanger life. The impact is particularly serious.
Of course similar to watches, this mechanical watch is slightly more expensive than a quartz watch. If your data center is facing high costs, limited space, and insufficient reliability, if you are more concerned with the total cost of ownership, rather than the one-time investment, consider the flywheel UPS. Since then, you will have to remove the battery. Replacement, maintenance and other troubles.
