A Non-unit Protection Scheme for Series-Compensated ...

The main challenge for fault direction and detection estimation method is a series capacitor and its protection unit. In the case of distance relay, when any fault occurred in protected line, impedance seen by relay may change because of the series capacitor which may result in mall operation of the relay. Fast and reliable fault detection, direction estimation, and …

A comprehensive review of DC fault protection methods in HVDC ...

Double-ended protection schemes may not be suitable for the HVDC line main protection because of the long communication delay especially for long lines. A single-ended protection scheme based on transients provides faster protection, and the DCCB can be operated with the current limiting reactor (CLR) to reduce the DC fault current [ 152, 153 ].
