Following the catastrophic 2014 ice storm, ELES commissioned the
development of the DTRi (Dynamic Thermal Rating icing) module as part of the
SUMO (System for the Determination of Operating Limits) system. The task of the
DTRi module is to calculate the minimum value of the current in a phase conductor at
which the conductor surface temperature does not drop below freezing. DTRi is a
stand-alone module that runs the corresponding calculations for the times
(from this moment up to a day and a half ahead) based on the ice alarms sent by ARSO
(Slovenian Environment Agency). The DTRi module delivers the results of the
calculations to the SUMO BUS service bus (application server with web services for
the SUMO system), where they are available for further use. So far, the interpretation
of the results has been carried out on the ODIN-VIS visualization platform (name of
the EES Advanced Visualization System), which serves as a support tool for operators
in control centers.
In the context of this master thesis, a deep integration of the results of the DTRi
module into the SCADA/EMS (Supervisory Control And Data Acquisition/Energy
Management System) has been carried out. Deep integration means the integration of
the DTRi data into the control system, which is the main tool of the operators, in such
a way that the module is seemingly presented to the user as one of the integral parts of
the SCADA/EMS system. sDeep Integration was designed as an upgrade to the display
of the results of the classical DLR (Dynamic Line Rating) module. It was designed in
accordance with the system requirements and the processing and display of the data is
automatic.
The master thesis describes the implementation of the individual elements of the
deep integration. Finally, the DTRi deep integration is tested for correct operation and
performance.
