Substation automation has critical role in power systems. Substations are responsible for many protection, control and monitoring functions that allow robust routing of power from generators to loads through a complex network of transmission lines. With the latest technology development many intelligent electronic devices (IEDs) available in substations today are capable of performing enhanced functionalities beyond what their basic function is. This brings an opportunity for adding new functionalities that go well beyond what the traditional substation automation solutions have provided. This presentation summarizes requirements for automated fault analysis functions that may be performed in substations in the future. Particular focus is on requirements for implementing a new concept of merging operational and non-operational data with a goal of improving fault analysis. The requirements are aimed at expanding the substation automation role in automated fault analysis towards better serving many utility groups: operations, protection and asset management.
