Abstract

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.

Description

technical field [0001] The invention is applied to the field of testing relay protection devices of intelligent substations, aiming at the templates for realizing intelligent automatic testing under the conditions of low testing efficiency, excessive reliance on labor and low testing accuracy, and specifically relates to a relay based on D-S evidence theory. Automated test template for electrical protection devices. Background technique [0002] As an important part of a strong smart grid, smart substations have been vigorously promoted and constructed in China, and intelligent secondary equipment such as intelligent relay protection devices have also been more and more widely used. At present, the smart substation adopts the IEC61850 standard, which strictly limits the functions, values, interfaces and other aspects of the protection device, realizes the standardization, standardization and unification of the design, and also provides convenience in the interactive sharing ...
