Secondary circuit closed loop monitoring system based on GOOSE input end mapping mechanism

Abstract

The invention provides a secondary circuit closed loop monitoring system based on a GOOSE input end mapping mechanism in the technical field of power systems. The secondary circuit closed loop monitoring system comprises a network communication module, a model analyzing module, a pattern generating module, a real-time comparing module and a data storage module. The model analyzing module analyzes SCD files from the network communication module, outputs an obtained static model of an IED device virtual terminal / virtual circuit to the pattern generating module, maps a GOOSE message feature value and a GOOSE input terminal to mapping definitions of a corresponding MMS model object, and outputs the mapping definitions to the real-time comparing module. According to an IED device standard drawing template prestored in the data storage module and the static model of an IED device virtual terminal / virtual circuit in the model analyzing module, by means of a template matching technology, the pattern generating module carries out matching on the IED device standard drawing template to generate an IED device secondary circuit diagram, and output the IED device secondary circuit diagram to the data storage module for visual display. According to the system, abnormal conditions of a secondary circuit and abnormal situations of a GOOSE control block, a dataset, goIDs and other key content can be found timely according to abnormality of a GOOSE message. Secondary circuit closed loop monitoring based on the GOOSE input end mapping mechanism is achieved, and reliable technical guarantee is provided for safe operation of an intelligent substation.

Description

Technical field [0001] The invention relates to an online monitoring system in the technical field of power systems, in particular to a secondary loop closed-loop monitoring system based on the GOOSE input terminal mapping mechanism. Background technique [0002] With the advancement of engineering applications based on the IEC61850 substation automation technology, the connection mode of the substation secondary equipment IED has replaced the traditional cable connection by optical fiber communication. The function association is defined by the GOOSE (Generic Object Oriented Substation Event) defined by IEC61850. Substation event) is realized. The secondary system of the substation is covered by the SCD (Substation Configuration Description) file. As a result, the entire secondary system of the substation becomes a black box, and the operation and maintenance personnel cannot visually observe the secondary protection, etc. The relationship between the equipment brings many diffi...
