IBERDROLA has awarded Ingeteam the contract to deliver Full Power Converters for the modernization of two Generating Units for the132-MW Torrejón hydroelectric plant on the Tajo River (Spain)
As part of the modernization, the plant will be converted to full power variable-speed operation.
For the Torrejón hydropower plant, Ingeteam Contract comprises 2x45-MVA 6.6kV water cooled Full Power Converters INGEDRIVETM MV900, including the power transformers and the electrical rooms for converters.
For the same project Indar, Ingeteam Group, is delivering the corresponding 2x45MVA –Vertical Motor-Generators, including excitation systems.
By modernizing and converting these units to Full Power Variable Speed concept, Ingeteam is making an important contribution to a more flexible use of hydropower plants and to increase the stability of electrical grid in Europe due to its high level of operating flexibility.
Variable speed Units offer several advantages for both pumping and generating modes such as:
possibility of active power control in pumping mode,
efficiency increase in generating mode especially under partial load,
wide range of operation,
additional Energy Generated/Stored compared to a conventional fixed speed alternative,
grid stability improvement by reactive power control, even with all groups stopped; the Full Power Converter can act as STATCOM, providing the necessary reactive power to the network, and
grid stability improvement by instantaneous active power injection in the grid (flywheel effect).
IBERDROLA is one of the world’s biggest electricity utilities with a total installed generating capacity of 52,084 MW, in Spain (26,627 MW), Mexico (9,532 MW), the U.S. (8,361 MW), Brazil (4,079 MW), the UK (2,520 MW) and other European countries (965 MW). The company’s renewable technologies include offshore and onshore wind, hydroelectric power, solar photovoltaic and combined cycle.
