Abstract

The invention discloses a method and a system for setting function selection of a relay protection device by adopting a menu interface. The method comprises the following steps of designing a basic function module corresponding to a basic function and a matching function module corresponding to different matching functions, and setting different attribute values Val for protecting data of the modules with different matching functions; setting different matching functions on a menu, and selecting the matching function actually required by the engineering field through the menu; and in the power-on initialization stage, shielding or opening logic processing being carried out on all the created data. According to the method, different matching functions can be selected and protected accordingto menus, engineering debugging complexity is reduced, and the risk of man-made uncontrollability caused by the fact that correct configuration needs to be downloaded according to the matching functions due to diversification of the protection matching functions in the prior art is solved.

Description

technical field

[0001] The invention relates to the field of electric power system relay protection, in particular to a method and system for setting function selection of a relay protection device using a menu interface. Background technique

[0002] Due to the complexity and particularity of the power system itself, the relay protection functions required by power grids and substations in various places are not completely the same. In order to take into account the different needs and operating habits of power grids and substations in various regions, a series of related standardized design specifications for relay protection and auxiliary devices are adopted to guide the development and configuration of relay protection devices. In this specification, the functions of protection devices are divided into "Basic model functions" and "optional software functions", each type of function is defined with a function option code. At this stage, mainstream relay protection manufa...
