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
The present invention relates to field of power, especially a kind of relay protection constant value intelligence check method and system of XML-based technology.
Background technology
Relay protection is one of most important secondary device of electric system, is the basic guarantee of safe operation of power system.According to information such as power system operation mode, protection configurations; the situation of adjusting of all relay protection constant values in the periodicity check system; in time finding and solve the relay protection device that has accident potential, improve the relay protection running management level, is the essential condition that ensures electric power netting safe running.
Continuous expansion along with the electrical network scale; the quantity of the secondary device that it is related will inevitably increase greatly; how in system's operational process, effectively to obtain equipment definite value real time data; and various relay protection constant values in the current system are carried out accuracy and rationality verification, just become the core content of secondary device operational management.Original Setting Management System of Protective Relaying adopts the internal system data structure that the relay protection constant value data are checked processing mostly, and the advantage of the method is that data structure is clear, be convenient to realize, but its shortcoming also is clearly:
The first, definite value is checked and is lacked standard, and different Management System Data format differences is larger, effectively unified management;
The second, value data re-defines, the different data model of protection definite value informational needs of correlation type, exploitation waste of manpower and the material resources of repetition;
The 3rd, the value data model does not have expansion, and when device configuration information changed, data model originally just can't meet the demands again;
The 4th, can't satisfy the data compatibility sexual demand of open platform under the Information Condition, data can't realize sharing between cross-platform.
