Supply of a two-speed high-voltage electric motor of type 2ADO-S to drive the VDN-25*2 blower fan for the needs of JSC "Quadra - Power Generation" - "Tambov CHPP"

Tambov CHPP is a thermal power plant, part of JSC “Quadra - Power Generation” (part of JSC Rusatom Infrastructure Solutions), located in the city of Tambov, Tambov region. Installed electrical capacity is 235 MW, the main type of fuel is natural gas, the backup fuel is fuel oil. The Tambov thermal power plant is the largest producer of electricity and supplier of thermal energy for consumers in the regional center. The Tambov CHPP generates about 30% of the electricity consumption of the entire Tambov region and provides heat to about 70% of consumers in the city of Tambov. Currently, the Tambov CHPP operates six steam boilers with a total steam output of up to 1680 tons per hour, four turbine units with an installed electrical capacity of 235 MW and 4 hot water boilers with a thermal capacity of 405 Gcal/h.

As part of the program to maintain the functioning of the energy complex of the branch of JSC “Quadra - Power Generation” - “Tambov Generation”, task on the replacement of the obsolete and already exhausted electric motor DAZO2-18-59-6/8 (manufactured by Armelektromash JSC), installed on the drive of a VDN-25*2 type blower fan, with a modern analogue. In this case, the electric motor must be mounted on an existing foundation.

In order to fully comply with the established technical requirements for performance, reliability and operating conditions, the EnergoFront company proposed a two-speed electric motor of type 2ADO-S-1600/800-6000-6/8-R-U1, produced by the domestic plant NPO "ELSIB" PJSC.

A long-term partner of EnergoFront is the company NPO ELSIB PJSC, which has established itself as a high-quality and reliable manufacturer of large high-voltage asynchronous motors used in the energy sector, oil refining, gas production and other industries in Russia. The company has many years of experience using modern technologies in the design and manufacture of large electric motors, generators and excitation systems.

The main advantages of the electric motor NPO "ELSIB" PJSC 2ADO-S series in comparison with the installed electric motor DAZO2-18-59-6/8 produced by JSC "Armelektromash" are:

• higher efficiency, as a result of reduced costs for the station’s own needs;

• higher permissible temperature of the stator winding, which allows the motor to remain in overload mode longer;

• stator winding insulation type “Monolit-4”, which increases the reliability and service life of the electric motor (for Armelektromash - 20 years, for ELSIB - 30 years);

• lower static and dynamic loads on the foundation due to the lower weight of the electric motor;

• a sliding bearing with liners with an elastic metal-plastic coating, instead of less reliable sliding bearings with forced lubrication;

• increased number of starts by 20% compared to the installed DAZO2 electric motor.

The above advantages of the electric motor of NPO "ELSIB" PJSC allow us to provide extended warranties: 36 months from the date of commissioning, 42 months from the date of shipment of the equipment from the manufacturer. Delivery of electric motors is planned ahead of contractual deadlines until the end of 2024.
