Argentina: The modernization process advances in the Yacyretá Hydroelectric Power Plant

This EBY release was published using machine translation.

The Yacyretá Binational Entity advances with the Modernization process of its Unit Control equipment.

One of the control systems to intervene corresponds to the Excitations of the Generators of the Vertical axis turbines.

The generator excitation systems are used to generate the rotating magnetic field in order to produce the design voltage electromotive force, the voltage control at the generator terminals and the stabilization of external electrical parameters in the event of electrical disturbances in the systems. Associated electrical.

To this end, in an International Tender process, the firm ANDRITZ Hydro LTDA was awarded for the execution of the Engineering, manufacturing, transportation, assembly and commissioning of the 18 new control units for 18 Generators.

The Contract entered into force on March 23, 2021 with an execution period of 36 months from the date.

On Friday, October 21, 6 trucks arrived from the ANDRITZ HYDRO Brazil Branch, transporting part of the supply, containing the Power system for self-excitation, made up of a voltage reducer transformer in dry insulation, rectification boards from Alternating Current to Direct Current and those corresponding to the automatic tension control of the
excitations for the Generators associated with each Turbine.

Each truck transports in the order of 21 tons of equipment, whose application is destined for each generating unit, totaling 126 tons for the first 6 units in this first delivery.

The Strategic Program aims to enhance the value of the Power Plant's generating park, maintaining the original features of the equipment and maintaining the installed power as well as extending the useful life of the entire renewable energy generation park after 30 years of generation. sustained.
Yacyretá, energy for a developing country.
