Pelton Turbine Generator 200kW High Head Hydro Unit Six Nozzle Runner Wheel

200kW Pelton Turbine Generator Set

This Pelton unit suits mountain stations with a water head from 120 m up to 800 m and a limited flow. The six nozzle runner wheel lets the unit run efficiently from 10% to 100% of rated flow, which is important where the stream flow drops sharply in the dry season.

Selling Points

• Six nozzle runner wheel. Nozzle group switching keeps part load efficiency high, and the unit can start on 10% of rated flow.
• Stainless steel runner. Cast and machined bucket profile in ZG06Cr13Ni4Mo resists silt erosion at high jet velocity.
• Deflector and jet brake. Hydraulic deflector closes the jet within seconds on load rejection, protecting the penstock from pressure rise.
• Compact powerhouse. Horizontal single or twin nozzle layout keeps the powerhouse footprint small on steep terrain.

Product Parameters

Supply Scope

• Pelton turbine with runner wheel, nozzle assembly and deflector
• Synchronous generator with excitation
• Microcomputer governor with jet and deflector control
• Inlet valve and manifold
• Control and synchronizing panel

Station Data Required

• Net head and head variation
• Design flow and minimum flow
• Penstock diameter and length
• Grid voltage and powerhouse layout

Why This Unit

High head sites are sensitive to runaway speed and water hammer. The deflector and jet brake arrangement limits both, while the six nozzle design keeps the unit productive when flow falls in the dry season. Bucket profile and stainless material extend runner life under abrasive silt.

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.
