Electric Power – hinnat ja saatavuus

Reducing power outage time to each customer is essential to the overall distribution reliability. This book provides the fundamentals of emergency operation using a graph-theoretic approach and exploration of the subsystem(s) that address the operational aspects of electrical fault occurrence to determine possible feeder reconfiguration. The localization of a faulted segment within a feeder involves remote-controlled normally open (NO) and normally closed (NC) switches through supervisory control and data acquisition (SCADA) between radially energized, interconnected feeders. Topics cover: (1) Data extraction from geographic information systems (GIS), (2) Graph modeling of distribution feeders, (3) Programming for backward/forward sweeping unbalanced power flow, (4) Short circuit analysis and fault localization, (5) Fault isolation, temporary and full service restoration, (6) Outage management and crew coordination, (7) Trouble call tickets and escalation to search for fault, and (8) Emerging subject of distribution management systems (DMS). FEATURES•Novel and practical textbook that will help to understand distribution operation in graph theory•Show how to convert GIS coordinate datasets to graph and how to troubleshoot the geometry errors•Explain how to troubleshoot power flow divergence due to the bad metering datasets and allocation factor (AF) for each load within primary and secondary networks•Similar platform as DMS environment, but the graduate students have their hands-on experience to implement the applications in the MATLAB environment•Detailed modeling in graph theory of distribution feeders and possible reconfiguration to locate power outage
