| Abstract: | This paper analyzes two maloperations of distance protective relaying on an 110 kV power feeder. And it compares the characteristics of the round distance-relaying component to that of quadrangular one, and discusses the different distance resistance sampling methods of mircoeomputer based relaying protection of high-voltage power feeder in common use. In the end, the improved setting principle and its feasibility and effectiveness have verified in practice. |
