Time Domain Distance Protection for Series Compensated Transmission Lines  Using RL and RLC Line Models

• Fast time-domain distance protection using RL and RLC models of a transmission line is presented in this paper for application to series compensated transmission lines. The proposed method is suited to both line-terminal andmid-line series compensation. It avoids classic limitations of delays and directional problems that phasor-based distance protection exhibits in series compensated transmission lines in the presence of voltage or current inversion sand subsynchronous oscillations. The method is validated with different system parameters such as compensation levels, source impedance ratio, fault inception angle, and fault resistance. The proposed method works well, with operating times in the range of a half cycle.
