Summarize this article for a 10 year old
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations. It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems.[1] The abstract data models defined in IEC 61850 can be mapped to a number of protocols. Current mappings in the standard are to Manufacturing Message Specification (MMS), GOOSE (Generic Object Oriented System Event) [see section 3, Terms and definitions, term 3.65 on page 14[2]], SV (Sampled Values) or SMV (Sampled Measure Values),[3] and soon[when?] to web services. In the previous version of the standard, GOOSE stood for "Generic Object Oriented Substation Event",[4][5] but this old definition is still very common in IEC 61850 documentation.[6] These protocols can run over TCP/IP networks or substation LANs using high speed switched Ethernet to obtain the necessary response times below four milliseconds for protective relaying.
