Abstract

Stalnim razvojem elektroenergetskog sustava njegovo vođenje postaje izuzetno složeno, uz povećane zahtjeve potrošača za količinom i kvalitetom električne energije. Osim održavanja ravnoteže između proizvodnje i potrošnje potrebno je zadovoljiti i sigurnosne uvjete. Zadatak ovog rada je kroz teorijski dio opisati metode i proračune koji se koriste u analizi sigurnosti. Prikazano je modeliranje pojedinih elemenata elektroenergetske mreže uz pomoć karakterističnih parametara i ekvivalentnih shema te su objašnjeni postupci procjene stanja i procjene sigurnosti. Najčešća metoda koja se koristi kod proračuna sigurnosti je analiza sigurnosti N – 1, u radu su objašnjene i tri metode proračuna tokova snaga pomoću kojih možemo napraviti analizu sigurnosti N – 1. U praktičnom dijelu rada na modelima IEEE test mreže od 24 i 48 čvorišta napravljena je analiza sigurnosti N – 1 u programskom alatu Neplan te su prikazani kritični elementi mreže.

Abstract (english)

Continuous development of the power systems results in extremely complex management and control issues, featuring increasing consumer demand for the quantity and quality of electricity. In addition to maintaining the balance between production and consumption it is also necessary to satisfy the security requirements. In the scope of this thesis methods and calculations used in the safety analysis are theoretically described. Modeling of individual elements of the electrical network through use of characteristic parameters and equivalent schemes is presented as well as procedures for state and safety estimations. The most common method used to calculate the safety is contingency analysis. Thesis also explains the three load flow calculation methods through which contingency analysis can be performed. In the practical part of the thesis contingency analysis has been conducted on models of IEEE test network with 24 and 48 nodes, together with presented critical elements of the network. Electrical network was modeled and analyzed using Neplan software.
