Power Flow solutions details feature allow users to request and review power flow solution details to identify areas of the model with data problems. Non-administrative users have access to Power Flow Solution Details for all real-time based power flow solutions, which are auto-generated; administrative users also have access to real-time Power Flow Solution Details and also have the ability to force generation of details for forecast and study mode power flow solutions.
The solution details page is available from the Viewer's Device Details Power Flow Results tab, from the Feeder Load Management Feeder Load Overview table, and from the Feeder Load Summary.
