The complexity and specialty of the protective relaying system and communication network configuration will be taken into account. The research has an orientation towards practical considerations such that the research results can also be integrated in the existing EMS/SCADA systems of power companies. The research task includes the reliability performance evaluation of the protective relaying configuration and the communication quality. The two-year proposal is planning to carry out in the following two stages: The first year (2004): This project has been approbated by NSC and has been executed since August 1, 2004. Some exciting results have been obtained. The schedule report of the project performed can be found in Table C012 of the project proposal for the next year (i.e. 2005). The second year (2005): In this stage, the effect of the transmission delay and transmission bite-error of the operation data of the power system on the performance indices of the previously designed protective relaying system will be evaluated. The Network Simulator v.2 and queuing theory will be applied to the study. First, the simulation system model for the mentioned topics will be established. The tolerance of the relaying system with respect to data transmission delay and loss will also be examined. The evaluation results will be concluded to propose a mathematical model that can be utilized to modify the design of the proposed relaying system. After the problems for the data transmission quality being resolved, the security and availability of the proposed protective relaying system will be promoted significantly.
