20.500.12556/DKUM-61794 VPLIV RAZPRŠENIH VIROV NA DISTRIBUCIJSKO OMREŽJE INFLUENCE OF DISTRIBUTED GENERATION ON THE DISTRIBUTION NETWORK V Sloveniji se poraba električne energiji z leti povečuje. Treba bo ustvariti ustrezno energijsko politiko, ki bo povečala pridobivanje električne energije in zmanjšala porabo le-te. Od leta 2005 se v slovensko distribucijsko omrežje priključuje vedno več razpršenih virov. Število le-teh in njihova priključna moč vplivata na kakovost električne energije. V diplomski nalogi je analiziran daljnovod 20 kV Podčetrtek, ki je priključen na srednjenapetostne zbiralke 20 kV v RTP 110/20 kV Rogaška Slatina. S pomočjo treh metod, izračuna po navodilih SONDO, modela v programskem orodju GREDOS in meritev z merilnimi instrumenti, je narejena primerjava porasta napetosti z razpršenimi viri in brez njih na daljnovodu 20 kV Podčetrtek. Na podlagi pridobljenih podatkov je ugotovljeno, ali se lahko priključijo dodatni razpršeni viri glede na priključno moč in porast napetosti. Consumption of electric energy in Slovenia has been increasing over the past years. There is a need to create sustainable energy policy, which on one side will increase production of electric energy and on the other side reduce its consumption. Since 2005 more and more distributed generation units are being connected to Slovenian power distribution system. Their quantity and connecting power influence the quality of electric energy. This thesis is analysing the 20 kV Podčetrtek overhead line, which is connected to medium voltage collectors 20 kV – substation 110/20 kV Rogaška Slatina. The comparison between voltage increase with and without distributed generation units on overhead line 20 kV Podčetrtek is made with the help of three methods, calculated in accordance with SONDO instructions, by using software tool GREDOS and measured with instruments. Information obtained enabled us to conclude, whether additional distributed generation units with their connecting power and voltage increase can be connected. distribucijsko omrežje razpršeni viri energije kakovost električne napetosti priključna moč kratkostična moč razdelilna transformatorska postaja SONDO GREDOS quality Power distribution system Distributed generation units Quality of electric energy Connecting power Short-circuit power Transformer substation SONDO GREDOS true true false G.
