A Novel Algorithm for Digital Distance Relaying
Distance relays are used to protect EHV and HV Transmission lines. Over the past decades many algorithms have emerged for digital distance relays. These are based on the calculation of the transmission line impedance from the relaying to fault points. In this paper a novel method for digital distance relaying is proposed. In the method the tracking procedure is implemented. The method uses the ...

متن کاملDistance Relaying Algorithm for a Single Line-to- Ground Fault on Single Infeed Transmission Lines
Modern power systems involve large amount of investment. An electric power system comprises of generation, transmission and distribution of electric energy. Growth of power systems has lead to very complex networks extended across large areas. In such situations, the proper functioning of a modern power system is heavily dependent upon the healthy operation of the transmission lines within it. ...

متن کاملEffects of CT and VT Connection Point on Distance Protection of Transmission Lines with FACTS Devices
This paper presents the effects of instrument transformers connection points on the measured impedance by distance relays in the presence of Flexible Alternating Current Transmission System (FACTS) devices with series connected branch. Distance relay tripping characteristic itself depends on the power system structural conditions, pre-fault operational conditions, and especially the ground ...
