SynchroGrid provided a relay coordination study for Cross Texas Transmission's entire 345kV system. The study included the analysis of several relay functions under normal and contingency conditions.

 

Relay Services:

  • Reviewed all line protection settings coordination using CAPE
  • Identified potential coordination issues for zone 1, zone 2 and zone 4 ground and phase elements
  • Checked mutual effects on ground distance elements
  • Identified deficiencies in Out of Step Functions
  • Provided relay setting report indicating settings changes
  • Provided new relay setting files with recommended changes
