Intelligent checking method and system for relay protection setting values based on extensible markup language (XML) technology

Abstract

The invention relates to an intelligent checking method for relay protection setting values based on the XML technology. The method includes the steps that a setting value collecting module collects and records setting value data of a plurality of protected devices simultaneously; a data double-calculation and check module loads corresponding setting value models automatically, calculates and analyzes the setting value data, and determines whether the setting value data exceed thresholds preset in the setting value models, and if yes, generates a setting value check abnormal report; and a check information publishing module loads the setting modules automatically, generates a device setting value early warning report, and publishes the report. The invention further discloses an intelligent checking system for the relay protection setting values based on the XML technology. According to the method and the system, the setting value models are not needed to be allocated according to each protected device, a rule base is checked through flexible allocation of the relay protection setting values, therefore the accuracy and rationality for checking the relay protection setting values are improved greatly, automated management during the whole process is achieved, and the device operation management efficiency is improved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an XML technology-based intelligent checking method and system for relay protection fixed value. Background technique [0002] Relay protection is one of the most important secondary equipment in power system, and it is the fundamental guarantee for the safe operation of power system. According to the power system operation mode, protection configuration and other information, periodically check the setting status of all relay protection settings in the system, timely discover and solve relay protection equipment with potential accidents, and improve the management level of relay protection operation. An important condition for the safe operation of the power grid. [0003] With the continuous expansion of the scale of the power grid, the number of secondary equipment involved will inevitably increase greatly. How to effectively obtain real-time data of equipment settings during sys...

AI Technical Summary

Problems solved by technology

[0004] First, there is a lack of standardization in the calibration of fixed values, and the data formats of different management systems are quite different, making it impossible to effectively manage them uniformly;

[0005] Second, the fixed value data is repeatedly defined, and related types of protected value information require different data models, and repeated development wastes manpower and material resources;

[0006] Third, the fixed-value data model has no scalability. When the equipment configuration information changes, the original data model can no longer meet the requirements;

[0007] Fourth, it cannot meet the data compatibility requirements of open platforms under the conditions of informatization, and data cannot be shared across platforms
