BAKU, Azerbaijan, Feb. 9
By Klavdiya Romakayeva - Trend:
The production of the first hydraulic turbine impeller at the Leningradsky Metallichesky Zavod (Leningrad metal plant), as part of the project to upgrade the Tupolangskaya Hydro Power Plant (HPP), has completed, Trend reports referring to the press service of Power Machines (Russian power engineering company).
It is reported that the wheel is intended for the hydroelectric unit (HU) No. 3. The completion of the manufacture of a complete set of equipment for the modernization of HA No. 3 is planned for the second quarter of 2021.
According to the information, the contract for the design, manufacture, and supply of hydraulic equipment for four hydroelectric units of the Tupolangskaya HPP was concluded with Uzbekhydroenergo JSC in 2019 and entered into force in April 2020.
It is noted that hydraulic turbines and generators with a capacity of 72.5 MW each will be manufactured for the construction of HUs No. 1 and No. 2. In addition, the scope of supply includes electrical equipment, process control systems, generator excitation systems, pre-turbine gates, and auxiliary equipment for hydroelectric power plants.
At the same time, new impellers, equipment for the modernization of turbine control systems, APCS, and excitation systems will be produced for operating HUs No. 3 and No. 4.
Also, the scope of obligations of Power Machines includes the provision of services for installation supervision and commissioning of the supplied equipment.
According to Power Machines, the commissioning of four hydroelectric units will be carried out in stages, the project is planned to be completed in 2022. The total capacity of the Tupolangskaya HPP will amount to 175 MW.
Thus, in addition to replacing the impellers HUs No. 3 and No. 4 will be equipped with modern turbine automation systems and automatic control of pre-turbine gates in the course of the modernization. The hydro turbines will be equipped with sensors for rotation speed, vibration and shaft breakage, an anti-acceleration device, new instrumentation, and electrical wiring.
It is reported that the construction of the Tupolangskaya HPP is carried out in two stages. At the first stage, HUs No. 3 and No. 4 with a capacity of 15 MW were put into operation. The equipment for them was manufactured by the Leningradsky Metallichesky Zavod and the Electrosila plant.
At the moment, the second stage of the project is being implemented - the expansion of the station's capacity to four HUs, due to the construction of two more units No. 1 and No. 2 with a capacity of 72.5 MW, as well as the replacement of temporary impellers with standard ones and the modernization of the equipment of control systems of small HUs No. 3 and No. 4.
