A major development in the field of hydroelectric power production, the Powerdrive frequency converter offers major advantages:
- Maximised annual production:
The Powerdrive frequency converter can be used to adjust the speed for installations with a high tidal range, with the turbine being used below its rated speed at low tide.
It is also possible to eliminate the gearbox if desired, thanks to the introduction of a standard slow-speed generator.
- Compliance with current and future legislation:
The Powerdrive frequency converter can supply or consume reactive power by eliminating the banks of capacitors from the installation and integrated management of reactive power by an electronic reference.
It manages microbreaks smoothly and efficiently and ensures immediate restarting.
- Reduced maintenance:
The Powerdrive frequency converter reduces racing and eliminates mechanical and electrical shocks on connection and disconnection. This makes it possible to do without the mechanical gearbox (on a Kaplan turbine), simplify mechanical flow regulation and eliminate the synchronous coupler.
Integrating the latest technical developments, the Powerdrive frequency converter comes in a cabinet, with ingress protection IP 20 to IP 54, and is air or liquid-cooled. It consists of a combination of standard modules; rectifiers, inverters, ventilation, control, assembled on a chassis, making maintenance simple and easy.A set of options are available for adaptation to any environment: fieldbus, add-on electrical protection, etc.
The existing range is suitable for power ratings up to 2800 kW at 690 V.
