Abstract: This paper presents the methodology of development wide-area protection and coordination (WAPC) for Provincial Electricity Authority (PEA) electrical transmission systems. The methodology of development WAPC consist of three main parts: the database management system, the evaluated operation of relays and the reconfiguration of miscoordinated relays. DIgSILENT Stationware software is used as a database management software and DIgSILENT PowerFactory is used as an analysis software. This proposed method could be applied to solve miscoordinated relays and to manage data. The proposed method has been implemented in the 115 kV southern 1 region of PEA transmission systems. The test results show the proposed method could be implemented to improve relay coordination. The method is easy to use, flexible and saving time.
Keywords: Wide-Area Protection and Coordination (WAPC), miscoordinated relays, DIgSILENT Stationware, DIgSILENT PowerFactory
