Abstract
Zaradi sprememb v elektroenergetskem sistemu, ki so posledica rastoče porabe električne energije, visoki stopnji rasti elektrifikacije energije, spremenljivim vzorcem odjema in hitre integracije proizvodnje iz obnovljivih virov električne energije, postaja potreba po optimalnem izkoriščanju prenosne infrastrukture vse bolj aktualna tematika. Na drugi strani je zaradi nasprotovanja javnosti in civilnih združenj gradnja novih prenosnih električnih poti praktično povsod po Evropi izjemno problematična, zato je skoraj edina možnost izkoriščanje obstoječih naprav do skrajnih meja. Električna omrežja bodo morala biti načrtovana, grajena, vzdrževana in vodena na tak način, da bo obratovanje z njimi kos vsem naštetim izzivom. Pritisk na izrabo obstoječih in bodočih elementov prenosnega omrežja bo vedno večji. Zato se pri družbi ELES v okviru projekta Sistem za ugotavljanje meja obratovanja (SUMO) uvaja sistem za ocenjevanje dinamične termične zmogljivosti daljnovodov, t.i. DTR (ang. Dynamic Thermal Rating), ki bo sistemskemu operaterju prenosnega omrežja na pregleden način podal oceno prenosnih zmogljivosti glede na trenutne in napovedane atmosferske razmere ter obremenitev EES. V magistrskem delu so predstavljene obstoječe tehnologije in stanje DTR v Evropi. V nadaljevanju so opisani glavni sklopi projekta SUMO. V okviru uvedbe sistema DTR je opredeljena pomembnost nadzemnih vodov na podlagi katere se bo določala smiselnosti uporabe DTR in o tehnologiji, ki bo pri tem uporabljena na posameznem daljnovodu v slovensko elektroenergetskem prenosnem omrežju. V ta namen je predstavljena metodologijo oziroma predlagana kriterijska funkcija ter kot končni rezultat je vsakemu daljnovodu slovenskega EES podana prioriteta za uvedbo sistema DTR in njegova potrebna natančnost.

Title:IMPLEMENTATION OF DYNAMIC THERMAL RATING SYSTEM IN SLOVENIAN POWER TRANSMISSION NETWORK
Abstract:
Due to changes in the electricity power system, which are caused by rising electricity consumption, high growth rate of electrification energy, changing patterns of consumption and rapid integration of the production of renewable electricity, a necessity for optimal exploitation of the transmission infrastructure is becoming increasingly important topic. On the other hand, the construction of new electric transmission paths across the Europe is extremely problematic due to public opposition and civil associations. Therefore, almost the only possibility is the exploitation of the existing devices towards the frontiers. Electricity networks will need to be designed, constructed, maintained and managed in such a way that they will overcome all of the above mentioned challenges. The pressure on the utilization of existing and future elements of the transmission network will be growing in the future. Therefore, ELES is within the framework of the project System for the determination of the limits of operation (SUMO), establishing a system for the dynamic thermal performance of transmission lines, the so-called DTR (Dynamic Thermal Rating), which will in a transparent manner provide the Transmission System Operator an assessment of the transmission capacity, given the current and projected atmospheric conditions and the load of the EES. The thesis presents the current technology and state of DTR in Europe. In the following, the main elements of the project SUMO are described. As part of the introduction of the DTR the importance of overhead lines on the basis of which the reasonableness of the use of DTR will be determinated is identified and the technology that will be used for a single transmission line in the Slovenian electricity transmission network. For this purpose, the methodology is presented and the criteria function proposed. As the final result, for each power line of the Slovenian electricity transmission network the priority for the introduction of the DTR and its required accuracy is given.
