Tashkent, Uzbekistan (UzDaily.com) -- The Leningrad Metal Plant (part of Power Machines JSC) has completed the shipment of a set of hydraulic turbine equipment manufactured for the first hydroelectric unit (HU) of the Tupolangskaya HPP in Uzbekistan.

Earlier, in 2021, Power Machines manufactured and delivered to HPPs hydro-turbine equipment for the modernization of HAs No. 3 and 4, hydro-generator equipment for HUs No. 1 and 2, as well as excitation systems for all four HUs. Currently, production of turbine equipment for HUs No. 2 is being completed at the production sites of Power Machines.

The commissioning of all four HPPs will be carried out in stages during 2022, as a result, the total capacity of the Tupolangskaya HPP will be 175 MW.

The contract for the design, manufacture and supply of process equipment for four hydroelectric units of the Tupolangskaya HPP was concluded with Uzbekhydroenergo in 2019 and entered into force in April 2020.

For new hydraulic units No. 1 and 2, hydro turbines and generators with a capacity of 72.5 MW each are manufactured. The scope of supply also includes electrical equipment, automatic process control systems, generator excitation systems, pre-turbine gates and auxiliary equipment of HPPs.

New impellers, equipment for the modernization of turbine control systems and excitation systems were manufactured for the existing hydroelectric units Nos. 3 and 4, the production of automated process control systems is underway.

The scope of obligations of Power Machines also includes the provision of services for supervised installation and commissioning of the supplied equipment.

In the course of modernization, in addition to replacing impellers, hydroelectric units No. 3 and 4 will be equipped with modern turbine automation systems and automatic control of pre-turbine gates. The turbines will be equipped with speed, vibration and shaft breakage sensors, an anti-acceleration device, new instrumentation and electrical wiring.
