Abstract:

 

In this paper, a novel protection method based on   time-time (TT) transform for thyristor-controlled series-compensated lines   is presented. First, current signals at both sides of the sending and   receiving ends are retrieved and processed through time-time domain   transform (TT-transform), and a TT-matrix is produced. A proposed index is   then compared with a defined threshold (THD) in order to determine fault   occurrence and faulted phases. Within less than three cycles of the fault   inception, a tripping signal can be sent that is acceptable for the speed of   digital relays. After faulted phase selection, considering the TT-matrix of   the faulted phases of both the sending and receiving ends, another index is   introduced for estimation of the fault section. Simulation results show that   this approach determines fault occurrence, faulted phase, and fault section   under different fault conditions such as fault type, fault location, fault   resistance, fault inception angle, source impedance, reverse power flow,   different levels of compensation, and different locations of the compensator   in the line. The test results in the presence of high noise (with SNR up to   15 dB) confirm the effectiveness of the proposed method. The results also   indicate that the proposed method is more robust to fault resistance   compared to previous studies.
