Real-time Distribution System Analysis - integral part of DMS

The paper describes modern trends in real-time distribution system analysis (DSA) - applications that are closely integrated with a SCADA based distribution management system. These applications traditionally include distribution power flow combined with load allocation, optimal volt/VAr control, Fault location, isolation and service restoration. They may also include optimal feeder reconfiguration, large area restoration, short circuit and zero sequence capacitor currents calculations. As more distribution management systems are being implemented in distribution utilities worldwide, real-time DSA applications are becoming more practically oriented, sophisticated in some areas, and simpler in another.
