Hydroelectric generation

Hydropower is electricity produced from flowing water. Hydropower produces approximately 7% of U.S. energy (19% of world energy) and accounts for 45% of total renewable energy in the U.S. Newer technologies harness energy in ocean tides, waves, and currents.

 

Hydroelectric Scheme

Applications

1. Intake, reservoir & tailrace level monitoring

the ability to reliably monitoring the intake reservoir and tailrace levels of certain types of Hydroelectric power plants provides operators with needed information to manage and control flow rates throughout the system.   Additionally, these...

2. Surge tank level monitoring

The main function of a surge tank is to control pressure variations due to rapid changes in the velocity of the water. When the power turbine is running at a steady load, there are no surges in the flow of water since the quantity of water flowing...

3. Dam seepage monitoring (flumes & weirs)

Dam seepage can be a serious problem over time. Many observations are taken into consideration in monitoring possible dam seepage issues including visual inspections, flow measurements, water property changes, sediment accumulation in the open...

4. Draft tube level & compressed air leakage

Some hydroelectric power plants can operate in two different modes: generator mode or synchronous condenser mode.

5. Oil/water interface detection

When seals fail, there is a possibility of water and oil mixing together either on the water or the oil side.  Both situations are highly undesireable, but water in the oil reervoirs is the worst of them as contaminated oil will not perform its...

6. Oil & hydraulic fluid reservoirs

Hydroelectric power plants have several large oil reservoirs for the lubrication of the turbine thrust and upper & lower guide bearings as well as other rotating equipment throughout the facility.

7. Pump protection & cooling water flow

It goes without saying that pumps should never run dry to ensure their proper operation and prevent unnecessary wear and tear of critical and expensive hardware.  Additionally, minimum flow rates for cooling water flow should be achieved prior to...

8. Air flow/ventilation monitoring (fans & blowers)

Fans and blowers must be monitored to ensure they are operating at their “Best Efficiency Point” (BEP).  Monitoring fan and blower air flow output provides a means of quantifying the performance and reliability of the ventilation system and...

9. Leak & flood detection (draft tube, sumps, pits, etc.)

All fluid leaks in a hydroelectric plant related to the operational equipment are contained in strategically located sumps and pits to be disposed of periodically.  Magnetrol offers a variety of Level switch and transmitter technologies to monitor...
