20.500.12556/DKUM-36732 ANALIZA VPLIVA RAZPRŠENE PROIZVODNJE NA OBRATOVANJE DISTRIBUCIJSKEGA OMREŽJA ANALYZING THE IMPACT OF DISTRIBUTED GENERATION ON DISTRIBUTION SYSTEM OPERATION Diplomsko delo obravnava model nizkonapetostnega distribucijskega omrežja, na katerem so priključeni porabniki in proizvajalci. V programskem paketu Matlab/Simulink je sestavljen dinamični model omrežja, ki nam omogoča izvesti analizo napetostnega profila pri različnih obratovalnih stanjih. V modelu so uporabljeni osnovni elementi elektroenergetskega sistema, kot so: transformator, vodi, porabniki in razpršeni viri. Ob vse večjem številu razpršenih virov v naših omrežjih se postavlja vprašanje o kakovosti napetosti in, ali lahko z ustrezno generacijo jalove moči v enotah razpršene proizvodnje vplivamo na napetostne razmere. Prikazani so rezultati simulacijskih izračunov z in brez razpršenih virov. The thesis deals with a low voltage distribution network that consumers and providers are connected to. A dynamic model of the discussed network was developed in the program package Matlab/Simulink. It enables the analysis of voltage profiles under different operating conditions. The model includes basic elements of the power system such as: a transformer, power lines, consumers and distributed power generation units. The increased number of distributed power generation units in our network imposes the question of voltage quality and appropriate generation of reactive power in the distributed power generation units. The thesis shows the calculated voltage profiles considering loads and distributed power generation units. distribucijsko omrežje generacija jalove moči napetostni profil kakovost napetosti distribution network generation of reacitve power voltage profile power quality true true false [Ž.
