Problems solved by technology

[0002] With the advancement of engineering application based on IEC61850 substation automation technology, the connection method of substation secondary equipment IED is replaced by optical fiber communication, and the traditional cable connection is replaced by the connection of functions. , the secondary system of the substation is covered by the SCD (SubstationConfigurationDescription, substation configuration description) file, but the tripping and closing hard pressure plate used as the intelligent terminal to connect the circuit breaker is not covered in the existing SCD file, and the operation and maintenance personnel cannot pass the SCD file. Complete management realizes the observation of the relationship between the protection system and the circuit breaker, and realizes the visualization of maintenance safety measures, which brings many difficulties to the operation and management of substations and increases the risk of substation maintenance and operation

Embodiment 1

[0020] Such as figure 1 As shown, this embodiment includes: several tripping and closing hard plate detection devices connected to the smart terminal and a control system connected to the smart terminal through the GOOSE network, wherein: the control system includes: a network communication module, a model analysis module and a graphic model Mapping module; the intelligent terminal collects the status measured by the tripping and closing hard pressing plate detection device and outputs it to the GOOSE network in the form of a GOOSE data set. The analysis module obtains the SCD file from the GOOSE network, analyzes and obtains the hard plate model corresponding to the smart terminal, and outputs it to the image-model mapping module; the image-model mapping module compares the state of the hard plate described by the smart terminal with the GOOSE data set, and matches the SCD For the hard press plate model in the file, the matching result is output to the background system throu...
