Protection and Reconfiguration of Zonal Distribution Systems

摘要

This research project focused in three areas. The first area developed fault detection and location schemes for ungrounded and high resistance grounded power systems. An evaluation of the impacts of different grounded schemes on system protection and power quality was conducted. The second area concentrated on developing schemes to isolate sensitive loads from voltage sags caused by faults and pulsed loads. One project developed a fault current limiter based on a vector-switching. A second implemented a static series compensator with a flywheel energy storage system to connect between sensitive loads and the system. The third developed an interface for pulsed loads combined with local energy storage. The third area of this project developed an analog model power system for testing protection schemes and power electronic converters.
