Sub-Harmonic Protection Relay Product Overview The S-PRO sub-harmonic protection relay protects generators, wind turbines, and SVC equipment from uncontrollable subharmonics 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. The easy-to-use S-PRO also provides control, automation, metering, monitoring, fault oscillography, dynamic swing recording and event logging with advanced communications. Protect against sustained sub-harmonics in wind farm operations Un-damped sub-harmonic current oscillations created by series capacitors interacting with the wind system can cause serious damage to wind turbine controllers and also to conventional generators. The wind turbine’s own mechanical system interactions (tower-to-blade) can also generate sub-harmonics, which are detrimental to induction generators and transformers, and may cause resonance at the point of common coupling in the electrical grid. The S-PRO relay detects these sub-harmonic oscillations and allows the utility to monitor and protect the power system by isolating the healthy grid from sub-harmonic generation sources. 10 Year WARRANTY www.erlphas
