Abstract

The invention provides a distributed localized relay protection system which comprises at least two sub-machines, wherein each sub-machine is provided with a startup processor, a protection processorand an instruction sending module, wherein the startup processor is connected with a first acquisition module; the protection processor is connected with a second acquisition module; the startup processor is configured to issue a startup instruction to the instruction sending module according to information acquired by the first acquisition module; the protection processor is configured to issue aprotection instruction to the instruction sending module according to the information acquired by the second acquisition module; and the instruction sending module outputs an instruction for performing a protection action after simultaneously receiving the protection instruction of the protection processor and the startup instruction of the startup processor. According to a technical solution provided by the invention, the instruction sending module outputs the instruction for performing the protection action to a relay protection device only after receiving the startup instruction and the protection instruction simultaneously, so that reliability of a distributed localized relay protection device can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system relay protection, and in particular relates to a distributed in-situ relay protection system. Background technique [0002] When the power system fails, the relay protection device needs to perform the relay protection action, and the prerequisite for the correct operation of the power system relay protection device is to be able to quickly and accurately receive the analog and switching values ​​that reflect the fault characteristics of the power system, etc. electrical characteristics. [0003] In order to improve the reliability of the electrical quantity characteristic sampling by the relay protection device, a series of measures have been taken in the design of the relay protection device of the power system, such as adopting the method of tripping two out of three to prevent the protection device from malfunctioning, and adopting the method of connecting two CPU modules in seri...
