Francis Turbine Generator 500kW Hydro Power Unit 400V for Small Hydropower Station

500kW Francis Turbine Generator Set

This 500kW Francis turbine generator set is built for small and medium hydropower stations with a water head of 25 to 120 m. The unit is supplied as a complete package: turbine, generator, governor, inlet butterfly valve, control panel and excitation system, so the station can be commissioned with one supplier responsible for the whole mechanical and electrical scope.

Selling Points

• Complete package supply. Turbine, generator, governor, inlet valve, control and excitation system from one factory, so interfaces are pre matched before shipment.
• Hydraulic profile matched to site. Runner and distributor are selected against the measured head and flow of the station, giving 92% to 94% efficiency at the design point.
• Brushless excitation. Static or brushless excitation with automatic voltage regulation, stable terminal voltage under load steps.
• Site support. Installation supervision, alignment and commissioning support available on request, with spare parts list for the first two years of operation.

Product Parameters

Supply Scope

• Francis turbine with distributor and draft tube liner
• Synchronous generator with excitation system
• Microcomputer speed governor with oil pressure unit
• Inlet butterfly valve with hydraulic actuator
• Control, protection and synchronizing panel
• Foundation and anchor bolt drawings

Station Data Required

• Net water head, minimum and maximum
• Design flow and dry season flow
• Grid voltage and frequency
• Tail water level and plant layout drawing

Why This Unit

The matched runner and distributor keep efficiency high across the flow range, which matters for stations running at part load through the dry season. Single supplier scope removes the interface risk between turbine, governor and electrical panel, and shortens the commissioning period.

Packing and Delivery

The unit is protected with rust preventive coating, fixed on a steel skid or packed in a seaworthy wooden case. Electrical parts are packed in moisture proof bags. Site drawings, test reports and the operation manual are supplied with the shipment.
