Distributed fault detection and isolation for power system
International Journal of Robust and Nonlinear Control, 2021AbstractIn this article, a novel distributed fault detection and isolation method is proposed for large‐scale power system affected by additive type of faults and energy bounded disturbances. First, in order to design the local residual generators, a bank of Luenberger observers are designed to estimate the local states of the system, and the ...

Lightning-Correlated Faults in Power Distribution Networks
2007 IEEE Lausanne Power Tech, 2007The paper deals with the correlation between lightning and distribution networks faults and/or voltage dips. In particular, the paper presents an application of a method proposed by the authors to correlate lightning events and relays operations based on the integrated use of: (i) data obtained from the Italian lightning location system (CESI-SIRF ...

Fault tolerance in distributed power systems
IV IEEE International Power Electronics Congress. Technical Proceedings. CIEP 95, 2002The demand for continuously available information processing systems increases every day. Transaction processing, communications systems, and critical processes all require nonstop, fault tolerant operation. There are four steps to achieving fault tolerance in any system. However, no system will operate without a supply of electrical power.

Single-phase power distribution system power flow and fault analysis
IEEE Transactions on Aerospace and Electronic Systems, 1992Alternative methods for power flow and fault analysis of single-phase distribution systems are presented. The algorithms for both power flow and fault analysis utilize a generalized approach to network modeling. The generalized admittance matrix, formed using elements of linear graph theory, is an accurate network model for all possible single-phase ...

Fault protection on shipboard A-C power-distribution systems
Electrical Engineering, 1944THE growth in the use of electrically driven auxiliaries on shipboard has produced very large increases in the installed generating capacity. This fact together with the necessity for maintaining a high degree of reliability and continuity of service in shipboard powerdistribution systems has emphasized the importance of providing adequate fault ...

Fault size distributions — are they really power-law?
Journal of Structural Geology, 1996Abstract Power-law fault size (throw) distributions spanning ca seven orders of magnitude are analysed using sample lines from seismic, coal-mine plan and outcrop data sets. Outcrop data sets generally have lower power-law exponent values than seismic data sets, consistent with a general decrease in exponent value with decrease in fault size. If such

Extended Fault-Location Formulation for Power Distribution Systems
IEEE Transactions on Power Delivery, 2009In this paper, an extended impedance-based fault-location formulation for generalized distribution systems is presented. The majority of distribution feeders are characterized by having several laterals, nonsymmetrical lines, highly unbalanced operation, and time-varying loads.

Voltage sag distributions caused by power system faults
IEEE Transactions on Power Systems, 2003Voltage sag distributions caused by faults at different voltage levels and experienced by low-voltage customers were established for four different power system areas. The shares of different fault types at each voltage level and the sag propagation throughout the power system were taken into account.

Fault-location Observability Analysis on Power Distribution Systems
Electric Power Components and Systems, 2014AbstractMost of the fault-location methods developed in the past employed measurements obtained from a limited number of meters installed in a power system. Optimal meter placement in power systems is to make the best use of a limited number of meters available to keep the entire network observable.
