Set of power electronics applicable in this design NCEs, provided the company Mitsubishi electric. In the test modes were tested the product in an uninterruptible power supply, and storage of recovered energy electrified urban land transport, subway, commuter trains Rossiykih railways. In addition, the approach was tested in a model of the IRC networks of large industrial energy users with sharply varying schedule of load consuming equipment and networks with alternative energy sources.
In tests the drive was attended by representatives from companies holding JSC "Russian Railways" JSC "Transneft", companies that use UPS to create powerful data centers, organizations petrochemical industry experts, venture investors.
The greatest interest among potential users of the kinetic storage capacity has caused rapid energy storage recuperated with high power electric transport during braking electric rolling before stopping. The stored energy is stored in the required time drives during stops and issued in a contact network to break cars. Calculations based on these experimental results show that the use of kinetic energy storage devices can save up to 30% of the energy consumed by electrotransport. This scope of the SCE can achieve high rates of economic efficiency that are inaccessible to other types of energy storage devices.
Also, high interest is the scope of the IRC as an uninterruptible power supply. Kinetic is able to drive quickly, within a few minutes, to store a large amount of energy to maintain the readiness of responsible energy consuming equipment categories. And if necessary, to give it a larger capacity in the consumer grid. Unlike traditional UPS chemical batteries, the storage element NCE — handwheel — not wear, so it is no replacement throughout the lifetime of the unit — more than 15 years. SCE has a number of important advantages over chemical batteries: lower operating costs, the lack of stringent requirements on climate protection areas, significantly higher efficiency, a much smaller footprint, no harmful chemicals, bezrazryvno of power supply in case of main power supply. Thanks to this, today the UPS market delineated steady growth of interest in the kinetic energy of the drives from the companies building and operating data centers and other facilities with a responsible energy-consuming equipment. Currently, UPS based on the IRC medium and large capacity for use as an uninterruptible power supply are being actively implemented in developed countries. Designed by "Russian superconductor" UPS-based storage of kinetic energy shows the characteristics that rivals the best world standards, and in some important ways significantly exceeds them.
The use of IRC on enterprise networks with a sharply uneven load schedule also achieves significant effects, experimental studies have shown the past. For example, the compensation of large peaks and dips in energy supply and, therefore, reduce the load on the equipment supply substations. Businesses that have or are planning the installation of local energy sources, can significantly reduce their power and, thus, capital and operating costs, as the peak load in this case offset by the energy stored in the flywheel. For businesses that purchase power from energy suppliers for the first time it is possible to significantly reduce the volume of its purchases. In addition, the IRC at the same time acts as a network filter, smoothing the jumps and dips voltage from the network.
As the general director of "Russian superconductor" Alexander Katz, the company in the near future is going to hold the certification process of the first model of the wide range of storage of kinetic energy. "We have already received inquiries from potential customers for the supply of kinetic drives, we are in a joint consultation on the introduction of the IRC in the energy consumer, provide estimates of economic benefit from their use," — said A.Katsay.
The immediate objectives of the company is to develop the next model with increased 3-4 times power consumption and power up to 300 kW, holding her tests, including at sites of real consumers.
