Power systems form the backbone of our modern society, supplying electricity for various applications. These systems are complex networks of generators, transformers, transmission lines, and distribution networks. However, they are susceptible to various faults, disturbances, and external factors that can lead to disruptions, equipment damage, and even safety hazards. Power system protection involves implementing mechanisms to detect and respond to abnormal conditions swiftly, preventing potential harm and minimizing downtime.
Among the many protection mechanisms, distance protection relays play a pivotal role in safeguarding power systems. These relays are responsible for detecting faults or abnormalities by measuring the impedance (distance) between the relay location and the fault point. Unlike conventional protection methods that focus on specific equipment, distance protection relays offer a comprehensive and holistic approach. They are particularly crucial in high-voltage transmission systems, where faults can be challenging to locate and mitigate promptly.
