Rezumat
Defectul in cascada este un mecanism uzual prin care se propaga defectele ce cauzeaza intreruperi mari ale
sistemelor de transport al energiei electrice. Pentru detectarea si eliminarea rapida a acestor perturbatii astfel incat sa se evite propagarea intreruperilor in cacada in intreaga retea de transport, se utilizeaza dispozitivele de masura sincrofazoriala
in timp real (PMU), care pot fi inglobate in diferite tipuri de sisteme de protectii pe arii extinse (WAP), sisteme de optimizare si control de urgenta, in vederea obtinerii unui management mai bun al securitatii sistemului prin strategii avansate de
comanda si protectie. Obiectivul acestei lucrari este de a scoate in relief beneficiile aplicatiilor WAP in vederea prevenirii blackout-urilor in sistemul de transport din nord-estul Romaniei utilizand infrastructura de fibra optica a CNTEE Transelectrica SA.

Abstract
Cascading fault is one common mechanism that causes large blackouts of electric power transmission systems. To detect rapidly and clear these disturbances so that to avoid the propagation of the fast-cascading outages in overall grid, it is used wide area real-time synchrophasor measurement system based on Phasor Measurement Units
(PMUs), which can implemented in different types of Wide Area Protection, emergency control and optimization systems for better management of the system security through advanced control and protection strategies. The objective of this
paper is to point out benefits of WAP applications to prevent of blackouts in the North-East Romanian power grid using
optical fiber infrastructure of CNTEE Transelectrica SA
