| Abstract: | This paper analyses various operation conditions of magnetically controlled reactor in HVAC transmission system, and introduces the protection configuration of reactor. Especially, reactor differential protection with automatic tracing and compensating rated current, reactor inter-turn fault protection based on time domain translation balance differential protection, and voltage differential protection of control winding are proposed. The results of digital simulation test, dynamic simulation test and field operation validate the proposed protections. |
