Abstract

U radu je prikazana metoda nadzora elektroenergetske mikro-mreže utemeljena na sinkroniziranim mjerenjima parametara elektroenergetskog sustava. U uvodnom dijelu rada opisani su dosadašnji SCADA sustavi i prednosti uvođenja modernih tehnologija fazorskih mjernih jedinica (PMU). Dat je pregled teorijskih osnova fazora kao i tehnologije mjerenja fazora u vremenima uzorkovanja reda veličine milisekunde. Opisane su metodologije nadzora na osnovu sinkroniziranih mjerenja te iskustva u primjeni u Hrvatskoj i svijetu. Prikazane su bitne prednosti uvođenja širokomrežnog nadzora (WAM). Nakon opisanih teorijskih osnova i postojećih primijenjenih sustava obavljena je analiza značajnih pogonskih događaja u UCTE sustavu kao i analiza simulacija primjene na realnom modelu laboratorija Riteh. U istoj simulaciji obavljena je analiza pogonskih događaja te su identificirane prednosti ugradnje ovakvih sustava. U zaključku rada opisane su najvažnije karakteristike PMU tehnologije i WAM sustava.

Abstract (english)

This paper presents a method of monitoring micro power system based on synchronized measurement of parameters of the power system. The introduction part describes the current SCADA systems and the advantages of modern technologies of Phasor measurement units (PMU). The review of theoretical basis of phasors and phasor measurements technologies which are working time samples in the order of milliseconds. Methodology of supervision based on synchronized measurements and experience in the application in Croatia and the world are described. The most important advantages of wide area monitoring functions (WAM) are displayed. The theoretical basis and the appropriateness of the existing system with the analysis of significant operational events in the UCTE system and the analysis of simulation applications in the real laboratory model Faculty of Engineering in Rijeka. In the same simulation, an analysis of operational events and the benefits of installing such systems are identified. In conclusion, this paper presents the most important characteristics of PMU technologies and the WAM system.
