Call for Collaboration: Design, Development and Testing of an Electricity Generating System for harnessing the kinetic energy of flowing water streams
ONGC Energy Centre proposes to Design, Develop and Test an Electricity Generating Systems for harnessing the kinetic energy of flowing water streams.
The following are the broad features and performance requirements of the proposed system.
| Technology | Suitable to harness kinetic energy of flowing waters from Open channels, Rivers, Canals, Tail race of Dams |
|---|---|
| Water velocity | Minimum of 1 m/s and the system should remain stable in velocities up to5m/s |
| Net Power Output |
3 - 5 kW at 220 V, 50 Hz at water surface speed of 1.5 - 2.0 m/s of the freely flowing waters It should be possible to transmit power to bank of river/canal through suitable cables to energize any motor or other electrical appliances. |
| Water to Power Efficiency | = > 45% when measured at water surface speed of 1.5 -2.0m/s, measured within the operating influence area of the system. |
| Submergence | Capable to adjust submergence. The system should be sub merged preferably> 40%. |
| Anchoring | Possible to anchor about a meter away from the bank |
| Operation and Maintenance Requirements | The system in waters for regular operations and withdraw for repairs/maintenance.
It should be designed in a manner that maintenance can be done on board either by reaching through a boat or by anchoring the system to the bank of the river/canal. The system when moored and working should have a mechanism to allow maintenance crew to board and de-board the system. The system should have the capability to handle floating debris so as to prevent them from entering the blade area. |
| Safety Features / Requirements |
The system should be safe, stable and operational in water speeds up to 5m/s. There should be a provision for automatic breaking in the event of excess water velocity (>5m/s), turbulence or obstruction in the water flow. It should have a safety net at the rear of the system to rescue accidental fall of personnel. |
| Instrumentation |
Measuring equipment to record on real time basis in a data logger, parameters like inlet and outlet water velocity at different points of contact, torque developed, RPM, power, voltage, current, pH value of water, air velocity etc. should be mounted on- board with digital display and USB or RS 232 output (preferably both) for connecting to data logger system. |
| Performance Testing |
The initial performance testing of the system is to be done in a test bed for measuring the efficiency and performance under standard test conditions. The system should be tested in flowing waters in a river/canal/tail race etc. for a period of one year |
ONGC Energy Centre (OEC) invites interested academic/research/industrial organizations to jointly work on this developmental project with ONGC Energy Centre. The proposed work also envisages simulation studies to assist in optimization of the design and sizing of the system.
Interested organizations are requested to send a technical note (about 4 pages) giving their views on the proposed broad features and performance requirements of the Electricity Generating Systems for harnessing the kinetic energy of flowing water streams to be jointly developed. This note should also include the proposed methodology and outline of design approach for further discussions with OEC.
