INTRODUCTION Distribution networks are characterized by a design short-circuit (sc) capacity, i.e. a maximum fault current to be never exceeded, related with the rating of switchgear and the thermal and mechanical endurance of all equipment and standardized constructions. Distributed generation (DG) resources are typically connected to distribution networks, at the low or medium voltage level, and therefore contribute to the total fault level of the network, roughly determined by the combined short-circuit contributions of the upstream grid and the various DG sources within the distribution network https://documentslide.com/documents/calculation-of-the-fault... ccccccccc 2.2 Uzgodnienia projektowe Na podstawie informacji dostarczonych przez użytkownika dostawca energii musi podać Wielkość mocy (kVA) i poziom prądu zwarciowego Koszt rozdzielnicy jest najczęściej mniejszy (poziom prądu zwarciowego jest niższy). ocena poziomów doziemnych prądów zwarciowych na etapie projekto http://www2.schneider-electric.com/resources/sites/SCHNEIDER... cccccccc W przypadku mikroźródeł należy również pamiętać, że takie źródło wnosi określony udział w prądach zwarciowych podczas wystąpienia zwarcia w takiej sieci. https://yadda.icm.edu.pl/baztech/element/bwmeta1.element.baz... cccccccccc Kraje europejskie posiadają kodeks sieci, który określa obowiązki zarówno operatorów systemów dystrybucyjnych, jak i wytwórców przyłą- czonych do sieci (np. charakterystyki regulacji, udział w prądzie zwarciowym itp.). http://copperalliance.eu/docs/librariesprovider3/8_1_generac... |

Reference: Calculation of the fault level contribution of distributed generation to distribution network Reference information: ABSTRACT Paper deals with the calculation of the fault level contribution of distributed generation according to IEC Standard 60909. To illustrate its application, the methodology is applied to a study medium voltage network with a variety of distributed generation resources. 1. INTRODUCTION Distribution network are characterized by design maximum fault current, i.e. short-circuit capacity. Distributed generation resources are typically connected to the distribution network, at the low or medium voltage level. Therefore they contribute to the total fault level of the distribution grid. Hence, the basic requirement for permitting the interconnection of distributed generation resources is to ensure that the resulting fault level remains below the network design value. http://home.zcu.cz/~tesarova/IP/Proceedings/Proc_2006/Files/... |
