S-PRO, Sub-Harmonic Protection Relay

The S-PRO sub-harmonic protection relay protects generators, wind turbines, and SVC equipment from uncontrollable sub-harmonics which cause

  • Sub-Synchronous Torsional Interaction (SSTI)
  • Sub-Synchronous Control Interaction (SSCI) and
  • Ferro-resonance

The S-PRO monitors potentially harmful Sub-Synchronous Oscillation (SSO) in real time & detects Sub-Synchronous Resonance (SSR) in transmission lines with power controller interactions such as FACTS or HVDC lines, particularly those lines with series compensation and interconnected with wind farms.
