This paper presents a new approach for transmission line protection using a time-frequency transform technique. The transform known as S-Transform (ST) is used for fault detection from the current and voltage signal at the relaying point. ST is an extension of wavelet transform and possesses ...
Distance protection is the main -protection of transmission lines and Plays a significant role in power system stabilization and security. This paper is focused on the problem associated with distance Protection of transmission line. Due to the inclusion of fault resistance in the ground faults, th...
Performance Evaluation of Distance Protection on Series Compensated Transmission Lines Transmission line protection needs to be adapted to the variations introduced by these devices. Installing series capacitors in a utility's network necessitate... KS Meera,S Subash,MMB Narayanan,... 被引量: 0发表:...
Existing distance protection of transmission lines depends on setting calculation to avoid operation under over-load conditions.After operation of distance protection,the line load transferring to other transmission lines may result in fault expansion,so it's necessary to find some new countermeasures to...
