چکیده :
The impedance observed by distance relays is calculated based on the sampled voltage and current at the relay location. Numerous non-fault events, which are probabilistic in nature, influence the observed impedance and the performance of distance relays. If these factors are not considered during the coordination and settings of distance relays, there is a risk of miscoordination. This paper proposes an interval-based approach for setting distance relays with quad characteristics, accounting for uncertainties to ensure maximum sensitivity and complete coordination between relay operations. Initially, the uncertainties affecting the settings of the three protection zones of the distance relay are modeled using the Monte Carlo method, and the impedance observed by the relay is determined for faults occurring both inside and outside the protection zones. Under these conditions, the observed impedance is modeled as an interval impedance for each relay zone. Subsequently, the settings for each protection zone are optimized to achieve two objectives: first, complete coordination among the zones; and second, maximum sensitivity for each zone. The proposed method is applied to a modified 8-bus test network, and its results are compared with conventional methods, demonstrating the superiority of the proposed approach.
