With the soaring connection of power electronics converter’s generation and loads in power systems, the fundamental characteristics and dynamic behaviour of the systems are changing. The well-known natural frequencies of the system can get excited by sophisticated and now fast-acting control systems and sustain a sub nominal oscillation. 

The tech talk is aimed to introduce the sub-synchronous oscillations phenomena and talk through different types, cause and effects, simulations, diagnostics, and mitigation methods. Related stability of inverter connected generation facilities will be discussed and examples will be presented of the past sub-synchronous oscillations events in South West Inter-Connected System (SWIS) and other networks.

Learning outcomes

In this presentation you will learn: 

  1. The phenomime of resonance in power systems and Sub synchronous resonance.
  2. Sub synchronous torsional interaction.
  3. Sub synchronous control interaction.
  4. Symptoms, consequences and mitigation techniques.
