High Efficiency Hydro Turbine Generator with Brushless Excitation and IEC Standards Compliance

Hydro turbine generators are driven directly or indirectly by hydro turbines, operating at rotating speeds below 1500r/min. They are available in both horizontal and vertical arrangements, with excitation modes including brushless and static silicon types. Key components consist of the stator, rotor, base frame, bearing, excitation motor, or collecting ring. These generators provide outlet voltages ranging from 400V to 13.8KV and support frequencies of 50Hz or 60Hz, with output capacities from 50KW to 50MW. Designed for high efficiency and reliability, all manufacturing and testing processes adhere to relevant IEC standards.

Hydroelectric generators comprise several main parts. Dynamos generate pulsing direct current through a commutator, while alternators produce alternating current. Mechanically, generators include a rotating part and a stationary part. The armature, which is the power-producing component, generates electric current for external circuits and can be located on either the rotor or stator depending on the design. The field winding or permanent magnets create the magnetic field necessary for operation. Electrically excited generators feature an excitation system to control field winding flux, whereas permanent magnet synchronous generators utilize magnets for this purpose.

The rotor is the rotating component in electrical machines, driven by the interaction between windings and magnetic fields to produce torque. The stator, being stationary, guides energy flow and converts rotating magnetic fields into electric current in generators. In fluid-powered devices, it directs fluid flow. One part generates the magnetic field, while the other induces electric current through wire windings.

Our generators are engineered for optimal performance, with a service life of 30-50 years and features such as PLC speed governors and various inlet valve options. They are suitable for a wide range of water heads and offer easy operation with efficiencies up to 94%. Supported by R&D and ISO9001:2008 certification, these units are ideal for diverse hydroelectric projects worldwide.
