Table 8 Performance comparison of different protection schemes.

From: Active line model identification protection based on characteristic frequency phase for dual-end weakly-fed AC system

Protection scheme

Two terminal weak feed AC system?

Affected by the accuracy of line parameters?

Fully consider the impact of control strategies?

The setting value depends on the simulation setting?
