IEC 61850 GOOSE Explained: Complete Guide to Fast Substation Messaging, Protection & Automation

GOOSE (Generic Object Oriented Substation Event) is one of the most important communication services defined in IEC 61850. It is used to exchange fast, event-driven messages between protection IEDs, bay controllers, and automation devices. GOOSE is designed to carry protection signals such as trips, interlocks, blockings, permissives, and alarms with very low latency and high reliability, replacing copper… Read More »

IEC 61850 MMS Explained: Full Guide to Reporting, Control, and Communication in Digital Substations

IEC 61850 is the modern communication standard used in power utility automation systems. It defines how intelligent electronic devices (IEDs) communicate inside substations and across modern electrical networks. One of the most important technologies inside this standard is MMS (Manufacturing Message Specification). MMS is used for supervisory communication, real-time monitoring, remote control, reporting, configuration, file exchange, and system… Read More »
