Comparison of water turbines
| Parameter | Screw hydro turbine | Kaplan turbine | Notice |
|---|---|---|---|
| Efficiency | 0 | 1 | The efficiency of the screw hydro turbine to 90%, Kaplan turbines to 93% |
| Annual electricity | 1 | 0 | Annual electricity production is higher by screw hydro turbine, due to operational reliability and uniformity of efficiency curve. |
| Reliability, floating solids | 1 | 0 | Lack of cleaning equipment and fine inflow screens. |
| Maintenance | 1 | 0 | Rare control of operating parameters |
| The cost | 1 | 0 | The cost of the screw hydro turbine is lower by 20% – 40% |
| Construction costs | 1 | 0 | The installation of Screw hydro turbine is more simpler- lower construction costs by 20% – 30% |
| Time frame construction | 1 | 0 | The time for installation of a compact srew hydro turbine is only a few days. |
| Icing | 0 | 1 | If it is too long outdoor temperature below -15 ° C frost it can be occur. Elimination with covering. |
| Patency for fish | 1 | 0 | Screw hydro turbine make possible downstream fish migration without their injury. |
| Noise | 0 | 1 | Outside residential zone is no problem, otherwise it is eliminated by covering. |
| Adjustability | 1 | 0 | Using frequency inverter speed range from 0 to 125% |
