Supply of two-speed high-voltage electric motors for the TDM drive for the needs of Vladivostok CHPP-2

Vladivostok CHPP-2 is a thermal steam turbine power plant with combined generation of electricity and heat. The installed capacity of the power plant is 497 MW, thermal power is 1051 Gcal/hour. The thermal circuit of the station is made with cross connections along the main flows of steam and water. VTETs-2 is the main source of supplying industrial steam, thermal and electrical energy to the industry and population of Vladivostok. This is the most powerful station in the DGK system in the Primorsky Territory. It is the largest energy facility in the south of the region, providing 60% of the needs of the city of Vladivostok with electrical energy and 63% with heat.

As part of the current large-scale reconstruction of the energy production and technological complex of the Vladivostok CHPP-2, the three oldest turbine units are being replaced and six worn-out boiler units are being dismantled, and three new ones of increased power are being installed in their place. Electrical and auxiliary equipment will be replaced, and the station building will be reconstructed. As a result of modernization, the station’s electrical capacity will increase to 574 MW, and its thermal capacity to 1,115 Gcal/h. The project is being implemented within the framework of the state program for the modernization of thermal energy in Russia. In addition to large-scale modernization, RusHydro is carrying out a complete conversion of the Vladivostok CHPP-2 to natural gas. The transition to gas significantly improves the environmental situation in Vladivostok: emissions are significantly reduced and ash and slag waste does not accumulate.

EnergoFront was faced with task for the selection and supply of six two-speed high-voltage asynchronous electric motors designed to drive smoke exhausters of the DN28x2BGM type produced by Sibenergomash-BKZ.

To ensure full compliance with the technical requirements for performance characteristics, reliability, operating conditions, as well as the Decree of the Government of the Russian Federation of July 17, 2015 No. 719 “On confirmation of the production of industrial products on the territory of the Russian Federation,” EnergoFront proposed an electric motor of the ADO-S-800/500-6000-8/10-R-U1 type from the domestic manufacturer NPO ELSIB PJSC.

The use of deep-slotted rotors with an increased volume of copper and good contact between the rods and the iron of the tooth makes it possible to reduce the heating of the rods during starts and guarantee reliable operation of engines with a number of starts over the service life of at least 5,000 for especially difficult starting conditions.

Reducing the temperature in the motor by several degrees due to the use of thermosetting stator insulation "Monolit - 4" allows you to increase the service life of the high-voltage stator winding and ensure trouble-free service of the winding for more than 30 years, as well as save the insulation from destruction and the motor from short circuit. NPO "ELSIB" PJSC is the only plant in Russia that has many years of experience in manufacturing motors with Monolit-4 insulation.

The above advantages of electric motors 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.

The production and delivery of equipment is carried out in batches according to the schedule for the reconstruction of the station complex, with a planned completion date of 2026.
