Ansaldo Energia Turbogenerators are designed for reliability.
They represent the perfect match for different types of Gas and Steam turbines, meeting the requirements of the prime movers and optimizing the conversion of the primary energy into mechanical energy.
Ansaldo Energia Turbogenerators offering encompasses different technologies, depending on the required power output – from air cooling to hydrogen cooling, and up to hydrogen/water cooling. All models can also operate as Synchronous Condensers. All models take advantage of Ansaldo Energia’s well known flexibility in matching Clients’ needs with tailored solutions.
THE HIGHEST OUTPUT RANGES
Ansaldo Energia hydrogen-/water-cooled generators (WT, THAR series), with water-cooled stators and hydrogen-cooled rotors, are top-level products for very high-power turbines.
Thanks to their high efficiency and quality, they ensure optimum and reliable operation for any turbine requirement – as witnessed by more than 60 installed units corresponding to >30 GVA.
They comply with all standards for safe operation in presence with hydrogen gas.
Dedicated auxiliary systems condition and circulate de-ionized water and hydrogen for cooling the system and keeping the shaft seals supplied with oil.
Static excitation units provide fast-response adaptation of the air-gap flux to load conditions. This allows the generator to provide stable power when operating on a network, and to keep the generator voltage constant during no-load operation or servicing.
HIGH PERFORMANCE AND LONG LIFE
Ansaldo Energia hydrogen-cooled generators (THR series) are used with gas turbines and steam turbines in single- or multi-shaft configuration. They are robust, reliable and easy to maintain.
Hydrogen provides for low frictional losses and increases overall performance.
Over 170 units installed since 1950 provide a total capacity of over 27 GVA.
Dedicated auxiliary system keeps the shaft seals supplied with oil.
The dedicated H2 skid conditions and monitors the coolant under all operating conditions, maintaining appropriate hydrogen pressure when in operation, and carrying on CO2 and then air purging during shut-down.
COMPACT FOR BASE AND PEAK LOAD
Ansaldo Energia air-cooled generators (WY/WX, and TRX TRY/TRX series) are robust, reliable and easy to maintain.
Air-cooled machines requires few auxiliaries to operate, and this reduces the initial investments to realize the plant.
Air-cooled generators can be adopted with gas turbines and steam turbines in single- or multi-shaft configuration. They can also be used in geothermal applications, where environmental conditions are particularly severe.
Air-cooled turbogenerators have indirectly-cooled stator windings and directly-cooled rotor windings. They are self-ventilated in a closed circuit with air-to-water coolers.
Specific solutions give the possibility to work under high overpressure to allow for further power extensions, or with light overpressure to install and operate the turbogenerator in hazardous areas (with ATEX certification).
