Kaplan Hydro Turbine Generator 1MW Low Head Unit Adjustable Blade Runner

1MW Kaplan Hydro Turbine Generator

This 1MW Kaplan unit is designed for low head river and canal stations with a head of 5 to 25 m and a large flow. Runner blades are adjustable through the oil head servomotor, so the unit keeps efficiency high when head and flow vary through the season.

Selling Points

• Adjustable blade runner. Blade angle follows the guide vane opening through the oil head servomotor, holding efficiency across a wide head and flow range.
• Low head capability. Runner and draft tube designed for 5 to 25 m head with a short, hydraulically efficient draft tube.
• Gearbox or direct drive. Speed matching by gearbox where the generator speed differs from turbine speed, with thrust bearing arranged for the vertical load.
• Silt and cavitation control. Blade profile and material selected against the sediment data of the site, with replaceable wearing rings.

Product Parameters

Supply Scope

• Kaplan turbine with adjustable blade runner and oil head
• Synchronous generator with excitation and thrust bearing
• Microcomputer governor with double regulation
• Inlet valve and shaft seal
• Control, protection and synchronizing panel

Station Data Required

• Net head range and design flow
• Flow duration curve
• Sediment concentration and water quality
• Plant layout, tail water level and grid data

Why This Unit

Double regulation keeps a low head station efficient when the river flow falls. Because head variation on run of river sites is large, the adjustable blade arrangement recovers several percentage points of annual energy compared with a fixed blade propeller unit, and the replaceable wearing rings keep the outage scope predictable.

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.
