This is a master thesis work carried out at the Department of Energy and Environment at the Division of Electric Power Engineering. The master thesis work describes the theory of distance protection relaying in 130 kV meshed distribution networks. The main aim of the thesis was to construct an Excel application for calculation and documentation of the settings for distance protection relays. The program is based on general methods for calculating settings of the different zones for the distance relay and presents the settings in simple graphics using quadrilateral characteristics. The reason for building an Excel based application is the great variety of distance protection relays in live networks. The manufacturers of distance protection relays make program for documentation available, however, they are based on the typical settings for the specific relays. Excel is in its later releases a powerful program for calculation, documentation and also graphics, and therefore Excel would be suitable as a platform for the intended application. Some suggestions for future work are also presented in this report.
