Dead Section Detection
This app focus on Voltage Unbalance type events with relevance to the detection, and location, of Dead Section situations in the Medium Voltage network. In the present version of the system, the events contained in this app are:
- VOLTAGE UNBALANCE
- VOLTAGE PHASE UNBALANCE
- MV DEAD SECTION
- MV DEAD SECTION VECT
Since the final goal of this app is to identify and locate Dead Section faults along the MV network, we need to have a representation of the MV network that contains the SDSs. In particular we need to know how the SDSs are connected along the MV grid, which mv feeder contains a given SDS and how SDSs in the same mv feeder are ordered. This way we can locate MV Dead Section faults by investigating the first SDSs that is showing Voltage Unbalance events consistent with a MV Dead Section.
Because of this need, besides showing the SDSs, we also represent in the map the MV PDS (Primary Distribution Substation) that feeds the SDSs.The MV feeders are represented by colours: SDSs of the same feeder have the same marker colour. In order words, in this app, markers colours are used to indicate mv feeders and not alarms. The existence of unsolved alarms in an SDS is represented by means of a cross over the marker, the colour of the cross indicating the highest severity among the unsolved alarms for a given SDS.
