Tiivistelmä
The amount of information generated in substation automation systems has grown exponentially since the introduction of Intelligent Electrical Devices (IED). Until recent years substation communication between IEDs was realized with proprietary protocols. This led to communication problems in systems with IEDs from different vendors. The IEC 61850 standard was introduced in order to harmonize substation communication and gain interoperability.
The IEC 61850 is an international standard defining communication networks and systems in substations. The standard defines substation functions, communication services and communication between devices as independent units. Thus the standard provides an opportunity for redefinition if technology in one area develops. The standard divides substation communication into three levels. This study focuses on horizontal GOOSE communication between IEDs in bay level and its applications. Horizontal communication has conventionally been solved by hardwiring required information between devices. GOOSE communication enables the transmission of these signals via Ethernet network, therefore creating a system that is more easily expandable and reducing the need of hardwiring.
The purpose of this work is to provide information for ABB Process Industry Plc concerning IEC 61850 and GOOSE. The substance of IEC 61850 and horizontal communication are presented in the theory chapters. The applications of GOOSE were examined in order to get more practical results. The applications were selected based on the capabilities of recently introduced REF615 IED. Each application is first described in general, followed by an example solution with REF615 IEDs. A fault arc protection application was selected for further testing based on an upcoming customer project. This application was configured between two REF615 IEDs and the functionality of the application was confirmed before the customer project was initiated. /Kir10
