Voltage sags caused by the short-circuit faults in transmission and distribution lines have become one of the most important power quality problems facing industrial customers and utilities. Voltage sags are normally described by characteristics of both magnitude and duration, but phaseangle jump should be taken into account in identifying sag phenomena and finding their solutions. In this pape...

Wildfires are one of the most hazardous natural disasters in Australia terms fatalities, property damage and financial losses. Events catastrophic wildfires recorded across world including United States Canada. Failures along power distribution infrastructure network faults have been identified as some causes for initiation wildfires. Thus, it is critical to better understand mechanisms potenti...

Boiler-turbines are one of the most important parts in power generation plants. The safety problem in such systems has always been a special concern. This paper discusses the application of control reconfig uration by fault-hiding approach for a boiler-turbine unit. In Fault-hiding approach, after occurrence of a fault, nominal controller of the system remains unchanged; instead, a reconfigurat...

After a transmission line fails, quickly and accurately find the fault point deal with it, which is of great significance to maintaining normal operation power system. Aiming at problems low accuracy traditional traveling wave location methods many affected factors, this paper relies on distributed monitoring points arranged lines study improve lines. First, when signal that moves both ends wil...

Frequency response analysis (FRA) is a sensitive ‎method established for testing the mechanical integrity of ‎transformers. However, interpretation of FRA signature still ‎needs expert opinions and there is no FRA interpretation code ‎generally accepted. Various mechanical faults with different ‎extents on power transformers are required to aid FRA ‎interpretation. To address this challenge, in...

Faults are the most critical tectonic factors in geological structures, which have major economic impacts on mining economics. Thus it is necessary to understand faults in order to identify the actual risks and complications associated with mining. In the preliminary investigation of the Sonda-Jherruck coalfield, 3D geological modeling was not performed. The purpose of this work was to perform ...
