POWER DISTRIBUTION NETWORKS PLANNING

Pregled svih elemenata planiranja distribucijskih mreža okisnica je u pisanju ovog rada. Općenita uloga planiranja i važnost distribucijskih mreža osigurava zadovoljnog potrošača i stabilizaciju vršnog opterećenja. Metodologija tehničkih i geografskih nephodna je u svrhu planiranja. Modeliranjem tehničkih značajki i topologije distribucijske mreže postiže se pouzdana isporuka električne energije. Na primjeru promatrane mreže u radu je objašnjena metodologija proračuna strujno-naponskih prilika, sigurnosti (n-1 analiza) i gubitaka. Razvojem suvremene tehnoligije i informatizacijom elektroenergetskih sustava razmatra se opcija prelaska na 20 kV pogonski napon imprementacijom modela analitičkog hijerarhijskog procesa (Analytic Hierarchy Process, AHP).An overview of all elements of distribution network planning is the main point of this paper. The general role of planning and the importance of distribution networks ensures a satisfied consumer and stabilization of the peak load. Technical and geographical methodology is necessary for planning purposes. By modeling the technical characteristics and topology of the distribution network, a reliable electricity supply is achieved. The methodology of calculation of current-voltage conditions, safety (n-1 analysis) and losses is explained on the example of the observed network. With the development of modern technology and computerization of power systems, the option of switching to 20 kV operating voltage by implementing the model of analytical hierarchical process (AHP) is being considered
