April 7, 2017

On the 31st of March, TYAZHMASH and Gidrospetsstroymontazh (Volgodonsk) signed the contract on supply of hydroturbine equipment for reconstruction of Belorechenskaya HPP hydraulic units Nos. 1 and 3. The first turbine will be supplied by 2018, and the second turbine will be supplied by 2019.

The contract value is more than 450 mln roubles. Under the contract, JSC TYAZHMASH is obliged to prepare technical documentation, produce, and supply two radial-axial hydraulic turbines (rated power is 24.65 MW) with electrocylinders, spare parts, and mounting facilities. TYAZHMASH is also obliged to carry out supervision installation and adjustment supervision of equipment.

One of the equipment main features is a complex geometry of runner blades. Moreover, TYAZHMASH will apply the unique technology — electrocylinders providing high-accuracy electromechanical control over wicket gate without oil hydraulic drives. This method of control is environmental friendly, it excludes oil leakages, and increases reliability and stability of control over hydraulic unit in normal conditions and emergency ones.

To achieve the required power ratings and efficiency factor, five various versions have been developed. The best version has been chosen to provide the required performance characteristics. During designing, the materials and technical solutions corresponding advanced worldwide standards have been used.

The owner of Belorechenskaya HPP is Lukoil-Ekoenergo LLC. It is the main supplier of power in the South of Russia. JSC TYAZHMASH has been cooperating with Lukoil-Ekoenergo LLC since 2002. Syzran plant has already manufactured and supplied equipment for hydraulic unit No. 2.
