Resonance and Ferroresonance in Power Networks

This TB provides an overview of the fundamental frequency resonance and ferroresonance in power networks starting with a thorough description. It then covers various network topologies that may lead to each phenomenon. Particular attention is given to shunt compensated transmission lines that can result in resonance. Ferroresonance in electromagnetic voltage transformers and power transformers are treated separately. Mitigation measures that can be employed to overcome resonance and ferroresonance are given in the form of active or passive measures. Guidance in modelling both phenomena and case studies are also provided.
