4-549: Generic Substation Events ( GSE ) is a control model defined as per IEC 61850 which provides a fast and reliable mechanism of transferring event data over entire electrical substation networks. When implemented, this model ensures the same event message is received by multiple physical devices using multicast or broadcast services. The GSE control model is further subdivided into GOOSE ( Generic Object Oriented Substation Events ) and GSSE ( Generic Substation State Events ). Generic Object Oriented Substation Events ( GOOSE )
8-716: A status list (string of bits) rather than a dataset as is used in GOOSE. GSSE messages are transmitted directly over IEC/ISO 8802-2 and 8802-3 using a similar mechanism to GOOSE messages (refer IEC 61850-7-1 Clause 12.2, IEC 61850-8-1 Clause 6.4). As the GSSE format is simpler than GOOSE it is handled faster in some devices. GSSE is being progressively superseded by the use of GOOSE and support for it may eventually disappear. Equipment manufacturers have started to offer non-standard protocols to report events over substation networks, citing advantages to these approaches. IEC 61850 IEC 61850
12-455: Is a controlled model mechanism in which any format of data (status, value) is grouped into a data set and transmitted within a time period of 4 milliseconds. The following mechanisms are used to ensure specified transmission speed and reliability. Generic Substation State Events ( GSSE ) is an extension of event transfer mechanism in UCA2.0. Only Status data can be exchanged through GSSE and it uses
16-774: 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. 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 ], SV (Sampled Values) or SMV (Sampled Measure Values), and soon to web services .
