An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Substation communication plays a vital role in power system operation. The power industry is changing; there is more or less a global electrical power market with international power companies. Thus, national differences in for example communication protocols, special substation automation solutions etc, are an economic obstacle when the international electric companies are seeking even better productivity and economic performance. It is therefore necessary to design Substation Automation Systems that are more cost effective to operate and maintain and that ensure quicker returns on investment than in the past. It is therefore necessary to design Substation Automation Systems that are more cost effective to operate and maintain and that ensure quicker returns on investment than in the past. This new perspective with reference to the conceptual design and engineering of modern control systems, has been the driving force for the new standard IEC 61850, with a global approach on communication and information handling.
GOOSE is an acronym for Generic Object Orientated System-wide Events. It aims to replace the conventional hardwired logic necessary for intra-IED coordination with station bus communications. Upon detecting an event, the IED(s) use a multi-cast transmission to notify those devices that have registered to receive the data. The performance requirements are stringent – no more than 4ms is allowed to elapse from the time an event occurs to the time of message transmission. The main objective of the paper is to provide a framework for Substation Engineers to simulate GOOSE messages for fast transmission of substation events, such as commands, alarms, indications, as messages which take advantage of Ethernet and supports real-time behavior with Motor protection Relay using KALKI protocol Gateway Lite for Substation Automation project. To generate GOOSE messages with Embedded Artists LPC2468 OEM Board.
