Fast Frequency Response

by | Jan 1, 2016 |

Fast Frequency Response  is a software module available to all GRIDlink products.

Respond to over or under-Frequency conditions by shedding or consuming load.

  • GRIDlink receives frequency reading every 1-2 seconds.
  • GRIDlink logs line frequency in the GRIDview Cloud if desired.
  • The system monitors both under and over frequency.
  • The user can set under and over frequency threshold limits with deadbands.
  • If the frequency drops below the threshold, Digital Output 3 will provide a 24VDC output to change the state of a relay to shed  load.
  • For over frequency, Digital Output 2 can be configured to change the state of a relay to consume energy.
  • A timing element requires the frequency go above or below the threshold for a configured amount of time before tripping the relay.
  • A configurable dead band in concert with a configurable time delay will determine when the system will return to normal.

Multiple relay outputs require Model VT-MIPM-135 ADR
