Common methods of protecting busbars include overcurrent-based interlocking schemes, overcurrent-based differential protection, high-impedance differential protection, and percentage differential protection. Busbar protection (BBP): Protection intended to detect and operate to clear faults on a busbar. In breaker and half scheme, five CTs method or four CTs method will be adopted for protection.

Lightning trip out of collecting line has become a serious threat to the safe and reliable operation of mountain wind farm. The differential current protection installed in 35kV Line of wind farm can remove the fault quickly, shorten the system fault time and avoid the shutting down of non-fault wind turbines, so that the stability of power system integrating wind farms is enhanced. The high magnitude fault currents require high-speed operation of the busbar protection to limit equipment damage. Tripping incorrectly for an external fault may cause large outages, and jeopardize power system.

If those currents on both sides match the protected object is assumed to be in healthy condition and relay remains stable (non operating). Busbar Differential Protection Definition: Busbar differential protection is a scheme that quickly isolates faults by comparing currents entering and leaving the busbar using Kirchoff's current law.

Busbar Differential Protection Definition: Busbar differential protection is a scheme that quickly isolates faults by comparing currents entering and leaving the busbar using Kirchoff's current law. The bus differential relay working principle is one of the most critical concepts in modern power system protection. Busbars are the heart of any substation, carrying power from multiple feeders, transformers, and generators.
