Regular Kaplan:  The low head & high flow machine !

The regular Kaplan units covers a range of 200-5000 l/sec. water flow at 2-25 m head, provides an electric output of 10-1000 kW, 3-phase, LV or MV, 50 Hz. It incorporates:

  • the hydro turbine, output draft tube and the PMSY  / SBSY  / SQIN  generator;
  • the MAS (microhydro automation system).

This turbine has a classic vertical shape, fixed or adjustable guide vane and rotor fixed or orientable blade design, and was developed for human safety, maximum reliability and easy maintenance. The End-user has to build the external hydro elements (retention dam, water intake, debris screen, 300 mm penstock pipe, inlet valve, draft tube, outlet canal - see PDF sketch) with usual materials (wood, fiberglass, concrete, PVC or metal pipe, etc.), based on a very simple design proposed in the offering stage.

If grid operated, the MAS includes a soft-starter for smooth connection. The speed is imposed (at rated value) by the grid frequency, while the generated power will then be solely determined by the available water head and flow.

If island operated, MAS will have to cope with the electric load variations. While the turbine runs at constant head, despite the speed and flow variation with the load, MAS will maintain the rated output frequency and voltage.

Depending on the site characteristics, several constructive variants (propeller, siphon, open flume, horizontal or vertical, etc.) of Kaplan turbines are available. Careful overall design has to be performed for all the technical aspects of the hydro station.
