Abstract: Based on the different characteristics of general substations from smart substations, there are more accurate requirements to analyze the abnormal impacts and to handle correctly in time when the abnormal intelligent equipment needs to be processed. This paper described the the abnormal intelligent equipment, took a 500 kV substation for example to analyze the intelligent equipment’s abnormal impact on the failure protection under special circumstances and put forward the handling measures, combining with three cases, which provides a feasible reference for the operation and maintenance personnel.
Key words: smart substation; intelligent unit; GOOSE network; exception handling; failure protection
