Optimization of the Operation Reliability Level of the Protection System.

Abstract

Ensuring the proper reliability level for the protection system is achieved by reserving the protection function. An excessive enhance of the reservation level leads to decreasing of the system reliability, due to the more situations in which protection tempestuously operates. The paper presents some considerations referring to definition of some indices regarding the protection system security. There is approached the problem of determination of the multiplicity level for each of the component protections, so that the optimization of the ensemble security level to be ensured. A more accurate analysis could be achieved by considering the corresponding phenomena as Markov processes.
