Po katastrofalnem žledolomu leta 2014 je podjetje ELES v sklopu sistema SUMO (Sistem za Ugotavljanje Meja Obratovanja) naročilo razvoj modula DTRi (Dynamic Thermal Rating icing – modul za žledni režim delovanja). Naloga modula DTRi je izračun minimalne vrednosti toka v faznem vodniku, pri katerem se temperatura površine vodnika ne spusti pod ledišče. DTRi je samostojni modul, ki na podlagi žlednih alarmov, ki jih pošilja ARSO (Agencija Republike Slovenije za okolje), proži ustrezne izračune za čase (od tega trenutka do dan in pol naprej). DTRi modul rezultate izračuna in jih dobavlja na servisno vodilo SUMO BUS (aplikacijski strežnik s spletnimi storitvami za sistem SUMO), kjer so na voljo za nadaljnjo uporabo. Do sedaj je bila interpretacija rezultatov izvedena na vizualizacijski platformi ODIN-VIS (ime sistema za napredno vizualizacijo EES), ki služi kot podporno orodje operaterjev v centrih vodenja. V sklopu te magistrske naloge je bila izvedena globoka integracija rezultatov DTRi modula v SCADA/EMS (Supervisory Control And Data Acquisition/Energy Management System). Globoka integracija pomeni vključitev podatkov DTRi v sistem vodenja, ki je glavno orodje operaterjev na način, da se uporabniku modul navidezno predstavlja kot eden od integralnih delov sistema SCADA/EMS. Globoka integracija je bila izdelana kot nadgradnja prikaza rezultatov klasičnega modula DLR (Dynamic Line Rating – dinamično termično ocenjevanje obremenitve vodnikov). Izdelana je bila v skladu z zahtevami sistema, obdelava in prikazovanje podatkov pa sta avtomatska. Magistrska naloga opisuje izvedbo posameznih elementov globoke integracije. Na koncu pa je izvedeno še testiranje pravilnosti delovanja globoke integracije modula DTRi in učinkovitosti njenega delovanja.

• Title: Deep Integration of Icing Module Into Slovenian Power Control System

Abstract

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.
