    Available Tools to Uncover Sub-Harmonics on Your Power System

As new and exciting sources of generation are brought online, the interconnected power system becomes ever more complex. Utilities are taking up the challenge, not only to monitor and protect against possible harmful frequencies, but to record and report that information as well, especially during system disturbances.

A deep knowledge of system interconnections is necessary to protect against possible transients that can result. A detailed view of system frequencies is extremely helpful to identify underlying patterns and predict potential for misoperation of the system. Especially at points of interconnection with the grid, it is also important to capture records that prove adherence to standards, and identify the sources of abnormalities after the fact.

S-PRO 4000 You will learn…
Sub-harmonics and hidden frequencies in the power system:

  • The concept of sub-harmonics
  • Effects of sub-harmonics
    • Induction generator effect
    • Torsional interactions
    • Toque amplification
  • Solutions for the effects of sub-harmonics
