Abstract: Seamless information exchange in smart substations is vital to ensure the successful operation of functions in a smart grid domain. IEC 61850 is an international standard that enables interoperability between devices in smart substations through standardized data model and communication services. One of the communication services defined in IEC 61850 is the generic object oriented substation event (GOOSE). The communication using IEC 61850 GOOSE replaces point to point copper wiring between intelligent electronic devices (IED) in conventional substations with high speed communication over Ethernet technology. However, the implementation of GOOSE has posed new challenges, mainly in monitoring and managing signals that carry specific substation functions. This is because with GOOSE, these signals are transmitted using single Ethernet connection which carries significant amount of information in a form of network packets at any point of time. Therefore, there is a need for power utilities who implement IEC 61850 standard in substations, such as Tenaga Nasional Berhad (TNB) to develop tools which are able capable in administrating and maintaining the features of IEC 61850 in substations. This paper will discuss the development of a prototype IEC 61850 GOOSE monitoring application which is a part of TNB IEC 61850 Substation Intelligent and Management System (61850 SIMS). This paper will also elaborate on the application development process, which is according to the Software Development Life Cycle (SDLC). The application is designed to represent IEC 61850 GOOSE information in terms and expressions that can be appreciated by conventional protection and maintenance engineers. The prototype application was successfully developed and tested at TNB IEC 61850 System Verification and Simulation (SVS) laboratory. This paper will also discuss on the application capabilities and new features that are planned to be included for future improvements.
