Multi-language achievement method for relay protection device

The invention discloses a multi-language achievement method for a relay protection device. The multi-language achievement method for the relay protection device comprises the steps that firstly, when the relay protection device is encoded, a code with protocol information and a corresponding expression character string are presented in a word at the same time; secondly, all character string resources and corresponding protocol codes in the word and a model file in the relay protection device are extracted through a PC tool, and a file to be translated is formed; thirdly, translation is carried out on the PC tool according to the language kinds set on the relay protection device, and translation language files are formed through the file to be translated; fourthly, the translation language files are downloaded into an HMI file management system; fifthly, the relay protection device runs, the corresponding translation language files in the HMI file management system are loaded according to the set language kinds, and corresponding language displaying is achieved. The multi-language achievement complexity of the relay protection device is reduced, meanwhile, the word compiling flexibility and multi-nation language support expandability are maintained at the same time, and good application prospects are achieved.
