Containerized Flywheel Energy Storage UPS System
1、Components of containerized flywheel energy storage UPS systems
The system consists of a flywheel energy storage UPS, a diesel generator set, an ATS intelligent control system, a lighting system, a smoke alarm system, an air conditioning system, aviation sockets, etc., and is designed to provide uninterrupted and long-term power supply for critical loads.
2、The functions of the main components in the system
UPS function: Through the rectifier and inverter inside the system, it filters out impurities and interference generated by the mains power supply, thereby serving important loads
It provides uninterrupted, high-quality power supply.
The role of flywheel energy storage: In the event of a power outage, the stored kinetic energy can be converted into electrical energy through energy conversion for diesel generators
It provides sufficient energy for the start of the group.
The function of the diesel generator set: It can supply power to the load for more than 6 hours in the event of a mains power failure.
ATS function: In the event of a mains power failure, it provides a dry contact signal to the diesel generator set, enabling it to start up quickly.
3、What a containerized flywheel energy storage UPS system works and diagram of how flywheel energy storage UPS works
Schematic diagram of containerized flywheel UPS system
Flywheel energy storage UPS schematic diagram
When there is a problem with the mains power supply, the static switch within the containerized power system instantaneously switches to the flywheel energy storage UPS to supply power to the load, while sending a start signal to the diesel generator set via ATS; When the diesel generator set has started up, the flywheel energy storage UPS synchronizes, locks the phase and gradually transfers the load to the diesel generator set, while the ATS switches the power supply circuit to the diesel generator set. When the mains power returns to normal, the ATS automatically switches to the mains power to supply power to the load while charging the flywheel, and the diesel generator delays the shutdown. Throughout the transition process, there will be no fluctuations in the load.

5 System advantages
Millisecond-level switching time
In the event of a mains power failure, the flywheel energy storage system can complete the switching in less than 3 milliseconds, fully ensuring uninterrupted power supply to the load.
Long live time of the system
The flywheel energy storage UPS is perfectly combined with the diesel generator set through intelligent control to provide uninterrupted, long-duration power supply for critical loads (sustainable emergency power supply for 6 hours when the fuel tank is full).
High reliability
The application of flywheel magnetic levitation technology eliminates unreliable components in the UPS, achieving a reliability of 99.99%.
Easy to maintain
It only requires an online oil change of the vacuum pump once a year.
Strong environmental adaptability
Low ambient temperature requirements. Compared with the strict ambient temperature requirements of battery-powered UPS, this system can adapt to complex environments and temperature changes, starting temperature -20 ° C - 40 ° C, operating temperature 0 ° C - 40 ° C; The cabinet is equipped with air conditioning, which can automatically adjust the indoor temperature according to temperature changes.
Low overall noise
With flywheel energy storage technology, it has features such as constant speed, low noise, and low friction, reducing noise emissions during operation. In addition, intake silencing, exhaust silencing and smoke silencing devices have been added inside the container. When mains power is normal, the noise is less than 45 decibels; When there is a power failure, the noise is less than 85 decibels at the moment the diesel generator starts and lasts for 15 seconds; After the diesel generator starts, the noise is less than 75 decibels until the diesel generator stops running.
