Guidelines for Subsynchronous Oscillation Studies in Power Electronics Dominated Power Systems (updated)

This Technical Brochure provides a general guideline for evaluating subsynchronous oscillations (SSO) in power systems. A new classification of SSO including the issues related to power electronic devices is proposed. A systematic study procedure including initial screening studies, detailed studies, mitigation / prevention techniques and protection/monitoring mechanisms is presented. The TB also discusses the industrial practises and the SSO issues reported in power systems.
