International Level Hydraulic Turbine Lab

      International-Level Hydraulic Turbine R & D Laboratory Brochure

      Hydropower Equipment Manufacturers, independent power producers, EPC contractors, consultants, government institution and others developing hydropower.

      Alternate Hydro Energy Centre (AHEC), Indian Institute of Technology (IIT), Roorkee has established an international-level hydro turbine R & D laboratory as design and validation facility in addition to conducting research in hydro turbines and other hydro mechanical equipment conforming to national and international standards.

      The laboratory shall support the Indian small and large hydropower industry (government as well as independent) to grow and compete in the International market in various aspects of hydroelectric power development.

• Spearheading research and development activity in the country for hydro turbine.
• Developing human resources for small hydropower in respect of entrepreneurs, engineers, plant operators and researchers.
• Generating data and building expertise for solving site specific problems.
• Providing affordable facility to small hydro manufactures for design verification.
• Validating designs of small hydro turbine and layouts using CFD technique.
• Developing and validating flow-measuring techniques leading to optimum utilization and generation.
• Providing calibration facility for measuring instruments used for both field-testing and power-plant operation.
• Providing facilities for testing and certification of turbines.

The guiding parameters in setting up this Lab are as follows:

• Good overall accuracy in turbine efficiency measurement (target 0.25%)
• Repeatability (target 0.15%).
• Limiting the normal power consumption in the Laboratory to 300 kW level.
• Meeting IEC 60193 and IEC 17025 requirements.
• Flexible rig to accommodate many types and designs of turbines.
• Test conditions and parameters to be stable.

TESTS ON SCALED MODELS

• Weighted average efficiency and turbine output
• Cavitation’s performance
• Pressure pulsation
• Run away speed

Besides above following tests are also conducted

• Characteristic Curves for the Turbine Quadrant
• Hydraulic Thrust
• Torque

      The laboratory is equipped with state of the art SCADA based automatic control system with electromagnetic flow meter, pressure transducers and sensors. The Laboratory has flow measurement tank and calibration tank. There will be a provision to calibrate the instrument against weight of water.
