State monitoring and tendency estimation device for secondary equipment of intelligent substation

Abstract

The invention discloses a state monitoring and tendency estimation device for secondary equipment of an intelligent substation. The state monitoring and tendency estimation device comprises a data acquisition access unit, a data comparison analysis unit and a comprehensive estimation output unit, and is characterized in that the data acquisition access unit receives operation state data of all sets of secondary equipment through various quick report mechanisms; the data comparison analysis unit receives various report data transmitted by the data acquisition access unit, decodes the report data, carries out associated comparison analysis according to a preset substation configuration file and outputs an analysis result; the compressive estimation output unit carries out intelligent estimation according to the analysis result of the data comparison analysis unit and provides estimation results of a secondary system and the secondary equipment. According to the state monitoring and tendency estimation device, normal state monitoring and counting on the secondary equipment of the intelligent substation can be realized, and a large quantity of abnormal signals can be judged, so that quick fault diagnosis can be realized, an effective instruction can be provided for shipment inspection staff, and the convenience in maintenance of the intelligent substation is improved.

Description

technical field [0001] The invention relates to the technical field of data monitoring, evaluation and early warning of an intelligent substation in a power system. In particular, the invention relates to a device for status monitoring and trend evaluation of secondary equipment in an intelligent substation. Background technique [0002] At present, the vigorous development of the power industry and the application of new technologies have made smart grids the future development direction of power systems. Smart substations are a key component of smart grids. Therefore, building smart substations has become an important task for the intelligent development of power systems. The smart substation is a new type of substation based on the DL / T 860 standard to realize information sharing and interoperability between the intelligent primary equipment and the networked secondary equipment in the substation. [0003] Compared with conventional substations, smart substations are qui...

AI Technical Summary

Problems solved by technology

However, in the actual operation of the smart substation, if the secondary system fails, it is very time-consuming to locate the fault point only by analyzing a single application association. It is necessary to analyze and compare the associated data from the interrelationships of multiple application associations. Horizontal and vertical integration to evaluate the operating status of various equipment and systems in the substation
