Abstract：The rapid development of power system has been made new requests to relay
protection, especially in a complex high-voltage power grid, in which all kinds of protections are important. As a protection device with perfect performance, distance protection can be applied to any complicated power systems with changeful methods of operation. Distance protection can remove faults from phases rapidly. According to the application of protection devices in power system, the passage which is divided into three chapters introduces the adjustment and configuration of distance protection in 10 kV power grid. First, this paper describes the research background, the significance of the research and the research status of distance protection as well as the main tasks.Secondly, the paper explains the summarize of distance protection, the theory and the principle of setting calculation. Chapter II focuses on the theory. Finally, the paper describes the setting experiment of distance protection in reality, including the theory of direction impedance relay, the adjustment method of distance protection between phases, the wiring diagram, DKB setting parameter table, the setting calculation of distance protection, experimental procedure and the analysis of experimental results. The analysis mainly explains the phenomenon and the problems encountered during experiment.
