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.
