INTRODUCTION
Real turbines can be tested at site in real conditions for which it is designed, only after installation and that too with relatively high inaccuracy. Practically no improvement can be done once the machine has been installed. The tests are therefore conducted on scaled models, on scaled hydraulic conditions. Such model tests process is a time consuming job and it demands well calibrated precision instruments, which are costly and often tailor made. Larger turbine manufactures such as BHEL, Andritz, Voith, GE and Dongfang have their own test facilities. However, smaller developers and consultants concerned with hydro power cannot afford such a big investment. Consequently, several projects have faced surprises during their operation.
HYDRAULIC TURBINE R&D LABORATORY, HRED, IIT ROORKEE |
|
|
A fully automatic SCADA based Hydraulic Turbine R&D Laboratory sponsored by Ministry of New and Renewable Energy, Government of India has been commissioned in 2017 at HRED, IIT Roorkee, Uttarakhand. HRED is a center of excellence for small hydropower in the country, to validate the homologous | hydro turbine models designed & fabricated by various turbine manufacturers. IIT Roorkee is one of the oldest technical institute set up in 1847 and has played an important role in the development of Water resources in India, both through education of competent engineers as well as research work. | |

OBJECTIVESThe laboratory shall support the Indian small hydropower industry (government as well as independent) to grow and compete in the International market in various aspects of hydroelectric power development:
|
|
|
The method used is simulating conditions similar to those around the runner of the turbine in a real hydro power plant. Two VFD driven large pumps are used for varying the water discharge, head and measuring various parameters such as power, discharge, head and speed in complete operating range.
HIGH-TECH FACILITYBoth CFD and experimental tests are carried out to validate the forecast performance and output test results obtained by calculation methods. The experimental tests are conducted for Francis, Kaplan and Pelton turbine by using a scaled model of the turbine. This stage of the hydraulic testing process provides a unique opportunity to verify the complete turbine operating range, taking into account complex operating phenomena, which are not covered in the theoretical calculation and tests carried out in previous CFD stages. This high-tech scaled model test laboratory is designed to test model of Turbine/ Reversible Pump Turbine/Large Pumps. The test rig is capable of simulating Conditions identical to those in a real hydropower plant.The guiding parameters in setting up this Lab are as follows:
|
The key parameters measured on this test-rig are Input hydraulic power i.e. head & discharge, output power i.e. runner speed and torque. This test-rig can measure mechanical power up to 132 kW, for speeds up to 1600 rpm, with maximum test heads of 60m with discharge 75 l/s and minimum test head of 10m with 907 l/s.
