Purpose of the development: Increasing the efficiency of turbines and propeller axial-radial type.

Recommended application field: Small hydro up to 10 MW, operating in parallel mode with the electrical system

Technical characteristic: The range of flow measurement - the nominal value of 0.2-1.0; range of the water pressure - the nominal value of 0.5-1.0; range of the speed - nominal value of 0.5-1.0

Advantages over analogues: The technology of the variable speed hydraulic units of small hydropower plants allows an increase of 20-30% efficiency turbine propeller and radial-axial type for arbitrary flow and pressure of water.

The development stage readiness: The working documentation is developed

Description of the development:
()
Using a discrete variable speed hydraulic turbines is realized through the use of asynchronous generators with a scale synchronous rpm b = 1,0 / 0,75 / 0,5 of the nominal value. Energy efficiency is achieved by matching the speed of the turbine rotor in accordance with the changing values ??of the flow and pressure of water. The developer offers the following services: study the economic aspects of the use of technology; development of technical specifications on the use of technology; to develop circuit solutions for the implementation of the technology; design engineering; support of commissioning; support pilot operation.
