The invention discloses a relay protection device automatic testing template based on a D-S evidence theory. The method comprises the following steps of (1), in a protection base module database, acquiring the parameter of each protection base module; (2), determining whether the same parameter exists among the base modules according to the D-S evidence theory, if yes, keeping one same parameter and combining the parts with the same parameter; after combination, if no same parameter exists, keeping the respective parameters for performing splicing combination; (3), after splicing, successivelyexpanding the testing items for testing; and (4), after testing, automatically generating a protection testing report. The relay protection device automatic testing template according to the invention is based on module splicing of the D-S evidence theory has advantages of preventing repetitive testing, improving testing efficiency, and laying a basis for intelligentization and automation improvement of the whole set of automatic testing system.
