Beschreibung
Zusammenfassung:	The present invention discloses a flexible direct current protection test method based on FT3 message switching value position collection. The method comprises the steps of: forming an FT3 message protocol database through obtaining of FT3 message protocols of different flexible direct current convertor stations, detecting FT3 data messages of a tripping outlet sent by a flexible direct current protection device in real time by a test system, analyzing the actual state of the position corresponding to the outlet in the FT3 messages according to the protocols, and employing the detected FT3 message to search corresponding protocols from an FT3 database according to LD names, and employing a closed-loop mode of externally sending FT3 message sampling signals and collecting FT3 tripping signals backwards by the test system to achieve closed-loop maintenance test of the scene protection logic of the flexible direct current convertor stations. The flexible direct current protection test method completes protection
