Intelligent Distribution Equipment for Fault Anticipation

چکیده
Condition monitoring of distribution equipment is essential for the prediction of distribution system failures. So, KEPCO developed intelligent distribution equipments that can diagnose its degradation conditions through special sensors and monitor its performance by a distribution automation system. Intelligent circuit breakers, switchgears, reclosers, transformers and surge arresters have been developed. These communicate with the distribution automation system’s control center via RTU by DNP3.0 protocol. KEPCO has also proposed diagnostic criterion for efficient maintenance. These pieces of intelligent equipment are installed in Jeju’s smart-grid demonstration area. Underground cable is also important distribution equipment but was not considered for on-line monitoring; however, an intelligent underground cable monitoring system is under development. This distributed temperature monitoring system uses fiber optic cables for improved efficiency and cable life. Failure prediction and prompt restoration will be possible because of rapid detection and location of

Decision Support for Distribution Automation: Data Analytics for Automated Fault Diagnosis and Prognosis
Distribution Automation (DA) is deployed to reduce outage times, isolate the faulted area, and rapidly restore customer supplies following network faults. Recent developments in Supervisory Control and Data Acquisition (SCADA) and intelligent DA equipment have sought to improve reliability and security of supply. The introduction of such ‘intelligent’ technologies on distribution networks, wher...
متن کاملAdaptive and intelligent control of permanent magnet synchronous motor (PMSM) using a combination of fuzzy logic and gray wolf algorithm under fault condition
Nowadays, permanent magnet synchronous motors have been widely used in industry due to the elimination of excitation losses, longer life and higher efficiency. Errors in engine and drive systems are unavoidable during operation. Therefore, a suitable scenario should be considered for when these systems fail. If the necessary predictions and control algorithms are not considered for the error co...

متن کاملCross Entropy-Based High-Impedance Fault Detection Algorithm for Distribution Networks
The low fault current of high-impedance faults (HIFs) is one of the main challenges for the protection of distribution networks. The inability of conventional overcurrent relays in detecting these faults results in electric arc continuity that it causes the fire hazard and electric shock and poses a serious threat to human life and network equipment. This paper presents an HIF detection algori...
متن کاملApplication of Multi-Agent Technology to Fault Diagnosis of Power Distribution Systems
When a fault occurs in a power system, the protective relays detect the fault and trip appropriate circuit breakers, which isolate the affected equipment from the rest of the power system. Fault diagnosis of power systems is the process of identifying faulty components and/or sections by analysing observable symptoms (telemetry messages). As the domain itself is characterised by dynamic situati...
