PRORAČUN STRUJE METALNOG TROFAZNOG KRATKOG SPOJA NA SN-IZVODU SA PRIKLJUČENIM INDUKCIONIM I SINHRONIM GENERATORIMA – REZULTATI PRORAČUNA

Abstract

The paper presents calculation results of the three phase short circuit current on the MV feeder with connected induction (IG) and synchroous (SG) generator using the theorem of superposition. Analyses were performed for 10 kV cable feeder. Mutual influences of connected distributed generators and distribution network were analyzed, with regards to the characteristic values of short circuit current during the periods of higher and lower loads. Rated powers of connected distributed generators were determined under condition that maximum value of operating voltage must not be exceeded at the connection points.
