Parameter sharing method and system for relay protection setting, terminal and storage medium

Abstract

The invention relates to a parameter sharing method and system for relay protection setting, a terminal and a storage medium, and belongs to the field of relay protection, and the method comprises the steps: obtaining the current equipment information of the current protected equipment; obtaining multiple pieces of protected equipment information and calculation model numbers corresponding to the protected equipment information from a preset protected equipment library, wherein the calculation model numbers are unique identifiers of current calculation models used for calculating the short-circuit current; according to the current equipment information and the protected equipment information, sequentially calculating and generating a plurality of equipment similarities; according to the maximum value of the equipment similarity, obtaining a calculation model number corresponding to the information of the protected equipment; obtaining a corresponding current calculation model according to the calculation model number; and substituting the current equipment information into the current calculation model to generate the short-circuit current of the current protected equipment. The method has the advantages that the calculated and generated short-circuit current is suitable for being used as the setting value, and the working efficiency is improved.

Description

technical field [0001] The present application relates to the field of relay protection, and in particular, to a parameter sharing method, system, terminal and storage medium for relay protection setting. Background technique [0002] Relay protection refers to an important measure that plays a protective role in the event of a power system failure. It can send an alarm signal to notify the staff and remove the faulty part from the main system in the shortest time and the smallest area possible. Generally speaking, the whole set of relay protection device consists of three parts: measurement comparison, logic link and execution output. Among them, the measurement and comparison part measures the physical parameters of the protected electrical components, and compares them with the given values, and gives a logical signal of yes or no according to the comparison result, so as to determine whether the protection device should be activated. [0003] One of the most common meth...
