Abstract
This thesis reports about the development of a novel way in detecting the power swing. The purpose of this project was mainly to come up with an algorithm that could allow the distance mho relay to distinguish between power swing and three-phase fault in order to avoid any maltripping from happening. The power swing blocker algorithm was developed and tested by using Matlab SIMULINK. The algorithm was based on the ratio of second over first voltage harmonics that was constantly measured in the line and then been compared with a threshold value. The threshold value was obtained by running a few simulations before deciding on one absolute value that could produce consistent performance of the power swing blocker algorithm. The simulation carried out with the power swing blocker embedded in the distance mho relay had proven the reliability of this new approach in power swing detection
