WatchDog Gamma Series for Wind Power Monitoring Applications

TELE Haase Gmbh             

Wind turbines are unmanned, local and autonomously operated power stations. Special monitoring technologies are needed for them to be safely operated.

Operational reliability demands that the battery charges be monitored in the UPS systems, which move the blades out of the wind in the event of malfunctions (vane position). Navigation light malfunctions and problems with the supply of power to the wind power generators also need to be rapidly recognized and reported.

Within the Process and Manufacturing  Sector, a major area for energy conservation via efficiency monitoring is Motor Driven Systems by electricity. This sector  comprises 20 -  25 % of the world's total electrical demand. In many countries, electrical demand is responsible for about 40% of greenhouse  gas emissions.

Electricity usage in Motor Driven Systems Electricity sector subdivides as follows:

  • Pumps                          20%
  • Fans/ Blowers              18%
  • Air Compressors         17%
  • Cool Compressors     11%
  • Conveyors                       3%
  • Others                            30%

Energy losses appear as heat. Robertson Technology has developed technology for measuring differential temperature to an accuracy of better than 1mK (0.001 Degree C), with long term stability.

This technology has been applied to the measurement of pump, water trubine and fan/blowers efficiency by the thermodynamic method ( Reference below: 1,2,3).

In pumping systems, the total possible energy savings is at approximately 40%, with the following breakdown:

  • Selecting a higher efficiency pump:          3%
  • Selecting a better-sized pump:                  4%
  • Better Installation / Maintenance               3%
  • Better System Design:                               10%
  • Better System Control:                               20%

Total Possible Energy Saving:  Approximately   40%

Accurate on-site measurement and monitoring is requires to achieve much of the above savings.  Robertson Technology provides the relevant products and services.
