Abstract:

 

This paper presents a novel approach for evaluating the  reliability of protective systems taking into account its components  reliability.  In this paper, a previously proposed extended model is  used for a directional over-current scheme.  In the extended model,  the impacts of individual protective components are taken into  account.  An optimum routine test schedule is determined for each  protective component as a separate unit.  A comparison is made to show  that the proposed approach has excellence over conventional routine  test inspections.  Impacts of factors such as circuit breaker  inadvertent opening, required time for performing routine test  inspections, human mistakes and self-checking and monitoring  effectiveness is analyzed using the model.  Redundancy in some parts  of the protective system is examined.  Permanent and transient faults  on the protected zone, operation of backup protection and common-cause  failures are also recognized in the model.
