Protection Modelling and Analysis of Energy Transmission Lines and Implementation for Ankara Region
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2019, Vol 7, Issue 2
Abstract
Providing transmission of energy continuously, reliably and high in quality is aim of transmission system operator. In order to achieve this short circuit faults in the power system should be detected by protection relays then faulty parts should be isolated immediately. Main purpose of this study is performing line protection analysis on simulation program in a regional base utilising real system parameters. In this study, 400 kV transmission lines in Ankara have been modelled and simulated in DIgSILENT power system analysis program and protection analysis is performed. It is investigated how a fault is cleared from the power system in cases such that the relay could not detect the fault or not operate, mulfunctioning of circuit breaker. Also it is inspected that effect of this situation on power system. Unlike other studies, real time load flow data and real bus systems are used for modelling. Settings of distance relays which are used in simulations are based on setting principles determined by transmission system operator. In simulations, different cases are investigated in terms of fault currents, behaviours of relays, lines became out of service. Results and suggestions are also presented.
