Abstract : With the continued expansion of transmission networks due to the growth in demand, protection engineers are expected to face big challenges. Thus, the protection engineers must focus on two major operational aspects: selectivity and sensitivity. Selectivity is the ability of a protection system to coordinate with other protection systems to minimize the outage-area when a faulted component of the system is isolated from the system. The sensitivity of the relay refers to the minimum operating quantities required for the system to detect a fault. The protection engineers face difficulties to undertake the coordination and relay settings manually. In fact, this option is impractical, and the probability of errors will increase, and the protection engineers will face some problems associated with relay mal-operation or restraints. However, with the existence of network simulation and protection devices performance analysis software; relay settings and coordination become more accurate and easy. Therefore, the protection engineers have confidence in doing relay settings coordination in the entire network. The goal of this thesis is to simulate the Saudi Western Region Network on Computer Aided Protectiocin Engineers (CAPE) platform and then implement the resultant values of the settings for protection devices as actually predicted in reality taking in consideration reviewing the values, looking for the weaknesses, and re-coordinating protection devices for the entire network to ensure that all protection devices are correctly operating in proper order. Following a thorough investigation in the current work several important highlights have become clear with regards to relay settings and system coordination especially the problem of infeed/outfeed on the second and the third zones have been resolved plus last lines of one zone.
