Small-Signal Sequence Impedance Theory & Applications

Presented by Prof Jian Sun of Rensselaer Polytechnic Institute (RPI) Webinar sponsored by the IEEE NSW Section, Joint Power Electronics / Industry Applications / Industrial Electronics Chapter. Characteristics of utility power systems are undergoing some fundamental changes because of the rapidly growing use of power electronics. The fast control of power converters introduces high-frequency dynamics, creating the potential for new stability and resonance problems that are above the frequency range of traditional power system stability studies and require new modeling and system analysis methods. Small-signal sequence impedance theory was developed to meet this need. It has been successfully used to solve practical resonance problems in various systems and is gaining broad acceptance in industry. This lecture introduces the theory and gives an overview of its applications as well as new developments.
