Abstract

Članek obravnava problematiko povečevanja priključene moči odjema v omrežju, ki že obratuje blizu mejne obremenitve. Za določitev maksimalne še sprejemljive priključne moči so v optimizacijskem postopku ukrepi prevezav, obratovanja v zanki in generacije jalove moči. Vsi so analizirani s pomočjo programa za izračun pretokov energije. Delo prikazuje rezultate izračunov pretokov energije na obstoječem razdeljevalnem omrežju. Izveden je bil izračun maksimalne moči dveh industrijskih odjemalcev, ki želita povečati odjem, na podlagi maksimalne obremenitve omrežja brez upoštevanja razpršene proizvodnje v omrežju. Izvedena je tudi analiza delovanja omrežja v zaključeni zanki pri normalni obremenitvi in obremenitvi z maksimalno močjo. Podana je rešitev problema previsokih napetosti v omrežju ob preveliki generaciji moči razpršenega vira v omrežju.

Secondary title: Optimization of distribution network operation based on reconnection, clossed-loop operation and reactive power generation - a case study
Secondary abstract: The paper deals with problems of increasing the load in the distribution network that already operates near the limit load. Optimization procedure with reconnections, operation in loop and reactive power generation is being used to determinate maximal acceptable load. All analyses are made with program for load flow calculations. This paper shows results of the load flow calculations on the existing distribution network. Maximal power of two industrial consumers, which want to increase their power, was calculated based on the maximal load of the network without considering distribution generation. Operation of network in loop is also analyzed at normal network load and at maximal load. Solution to problem of too high voltage in the network, because of big distribution generation, is presented.
