Implementation method for dynamic scheduling on protection components of relay protection device

Abstract

The invention discloses a method for implementing configuration on the protection function of the relay protection device and flexibly configuring real-time scheduling strategies for all protection components. A scheduling and configuring mechanism for the protection components is provided through the configuration software of an upper computer by adopting a graphical friendly mode, and binary scheduling strategy files which can be analyzed by the protection device are generated; after the files are analyzed by a platform program of the protection device, the elements are dynamically instantiated, and are mounted in a task scheduling chain table. Through the implementation of the method, the problems that the protection components in the program of the current relay protection device cannot be dynamically established or dynamically scheduled are solved.

Description

technical field [0001] The invention relates to the functional configuration of protection elements in the field of relay protection of electric power systems, in particular to a method for realizing dynamic call of protection elements of a relay protection device. Background technique [0002] The requirement for the configuration of protection components of relay protection devices has been proposed as an essential function since the beginning of microcomputer protection. Based on the limitations of previous hardware resources and software architecture, manufacturers have adopted protection control words and pressure plates to control whether certain protection functions are put into use. . This method has a large control granularity, and the control method is not flexible enough. Although the protection element exits the protection through the control word, the protection element is still created and initialized in the memory when the device is powered on, occupying the m...
