A new R&D lab to help small hydro power projects
It is estimated that India has the potential to generate 20,000 MW of power from small hydropower projects alongside rivers and irrigation canals.
Roorkee: It is estimated that India has the potential to generate 20,000 MW of power from small hydropower projects alongside rivers and irrigation canals.
The Government has been taking several steps over the year to realize this potential to meet the growing need for electric power in the country. The Ministry of New and Renewal Energy (MNRE), which is the nodal agency for promoting small hydropower projects, has aimed to harness at least 50 percent of the potential in the next 10 years. The present installed capacity is about 4,500 MW.
A major roadblock in converting the potential to reality has been in terms of testing of the hydro turbines that generate the electricity. They can be tested for their efficiency in real conditions only after they are installed and even then not only the results are not accurate enough but also no improvements can be done once the machine is installed.
Consequently, the tests are conducted on scaled models and on scaled hydraulic conditions. Such tests are time consuming and demand well calibrated precision instruments that are expensive and often tailor made.
Only large turbine manufacturers can and therefore, have their own test facilities. Smaller developers and consultants cannot afford such investments. As a result, several projects have faced surprises during their operation.
A solution is now available for the problem. The Ministry has set up a dedicated fully automatic SCADA-based hydraulic turbine research and development laboratory at the Alternate Hydro Energy Centre (AHEC) at the Indian Institute of Technology, Roorkee.
Set up at the cost of Rs. 40 crore, the laboratory will act as a design and validation facility and also conduct research on hydro turbines and other hydro mechanical equipment conforming to national and international standards.
It has the capability to conduct tests on scaled models of hydraulic turbines for various technical parameters such cavitation performance, pressure pulsation and runaway speed, characteristic curves for the turbine quadrant, hydraulic thrust and torque. The laboratory is equipped with state of the art SCADA based automatic control system with first principal based flow measurement, precision pressure transducers and sensors.
It has obtained accreditation from the National Accreditation Board for Laboratories (NABL) as per ISO/IEC standards for fluid flow testing and calibration. NABL is part of Asia Pacific Laboratory Accreditation Cooperation (APLAC), which, in turn, is part of the International Laboratory Accreditation Cooperation (ILAC).
