Novosibirsk State Technical University (NSTU) is developing a guaranteed power supply system to ensure continuous operation of industrial equipment. Video.
The development order was received from the scientific and technical center "Systems of guaranteed power Supply" (STC SGPS). The company supplies uninterruptible power supplies (UPS), in particular, for the oil and gas industry, where continuous operation of critical equipment such as drilling rigs, pumps, compressors, and pipeline equipment is important. Power supply failures can lead to downtime and financial losses, as well as problems with starting stopped units, since they have high starting currents, said Dmitry Stein, Deputy director of the Institute of Power Electronics at NSTU-NETI.
To ensure continuous operation, oil and gas installations are equipped with uninterruptible power supplies, which must be as reliable as possible and operate 24/7. The UPS protects the equipment from power surges, power outages, and provides battery power in case of power outage.
"In order not to manufacture an uninterruptible power supply for a specific application every time, we are developing a range of standard modules, including a rectifier module and an inverter module. As part of the Priority 2030 program, we are creating a universal control system for industrial uninterruptible power supplies with a capacity from 30 to 400 kVA. With the help of this system, various modules will be controlled, and it is also applicable when increasing UPS power. By the end of the year, we must produce and test it as part of the facility," Dmitry Stein said.
To date, a range of 10, 30, 60 kVA uninterruptible power supply systems has been developed. The modules are installed in a standard assembly cabinet, and the system is currently undergoing testing. The commissioning works are carried out at the enterprise "Promautomatics Systems". Energy indicators are checked: basic performance, quality of electrical energy, trouble-free operation in conditions of voltage fluctuations, functioning under conditions of different loads, different network parameters or the absence of a network.
The tests of the developed series of modules will last until the end of the year. After that, the customer will launch mass production of UPS units equipped with a universal control system, and NSTU-NETI will begin developing higher-power systems.
