Fault Current & Fault Voltage Analysis of Power Distribution Network
2018 3rd International Conference for Convergence in Technology (I2CT), 2018Power distribution networks such as distribution substations plays very important role while distributing power to the consumers. Analysis of fault for distribution network of power is very necessary. Fault analysis can be done by various methods such as symmetrical components, MVA method, percentage impedance, percentage admittance method, per unit ...

Power-Law Testing for Fault Attributes Distributions
Pure and Applied Geophysics, 2013This paper is devoted to statistical analysis of faults’ attributes. The distributions of lengths, widths of damage zones, displacements and thicknesses of fault cores are studied. Truncated power-law (TPL) is considered in comparison with commonly used simple power-law (PL) (or Pareto) distribution.

Fault level analysis of power distribution system
2013 International Conference on Energy Efficient Technologies for Sustainability, 2013Fault level analysis in power distribution system is important issue in power system protection study. Demand of power increases day to day. So, continuous power supply to the consumer is necessary without any interruption. Fault analysis in power distribution system is necessary for selection of proper protective devices such as relays and circuit ...

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
