Automated control for Power Transmission System in urban area

Modernization of a power system involves development and deployment of an Intelligent System or a System Integrity Protection Scheme for a Power Transmission System. As the observed urban Power Transmission System has a ring topology, including overhead lines and underground cables, various scenarios of a closed loop and island operation are considered. Deficiencies of a traditional control solution are stated and a modern automated control of the urban transmission system, based on synchronized phasor measurements, is presented. A developed architecture is designed to provide real time monitoring and control functions. Control actions are based on different switching and operational states.
