Intelligent substation configuration optimization method based on semantic modeling

Abstract

The invention discloses an intelligent substation configuration optimization method based on semantic modeling. The method comprises the following steps: firstly, performing 61850 modeling on secondary equipment according to semantics; secondly, configuring a system specification description SSD file, and associating each interval primary device with a standard interval name; specifying a standardLN for each interval primary equipment object in the SSD file, wherein the standard LN is used for associating the LN in the secondary equipment model; setting an IED _ NAME according to an IED general naming principle; directly associating the secondary equipment model instance CID file configured at each interval to a corresponding interval in the SSD, and establishing a corresponding relationship between the standard LN and each secondary equipment LN instance; designing a general configuration template of each functional module in the advanced application program based on the state information between the secondary devices; and instantiating the general configuration templates of the functional modules one by one according to intervals to complete the automatic configuration work of the functional modules at intervals. According to the method, the configuration working efficiency and quality of the advanced application function module based on the secondary equipment state information of the intelligent station can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations, in particular to an intelligent substation configuration optimization method based on semantic modeling. Background technique [0002] The IEC 61850 standard is the basis for the construction of smart substations. The 61850 series of standards adopt equipment object-oriented modeling technology, and adapt to the needs and development of application functions through model self-description. Confined by the limitations of the understanding of application requirements, starting from the earliest application of 61850 in China, the modeling of secondary equipment did not fully reflect the characteristics of the self-description of the model, and more 61850 was used as a general communication protocol. In substations, the realization of interoperability between equipment from different manufacturers has been able to meet the initial application requirements, but with the continuous deve...

AI Technical Summary

Problems solved by technology

[0008] To sum up, due to the unclear relationship between primary and secondary equipment, the data basis for advanced applications based on the state of primary and secondary equipment and the state information between secondary equipment within intervals is poor, and all configuration processes directly face the specific instantiation. For the device model, the configuration results of a single interval cannot be reused at all. It is necessary to configure signals one by one for each application function in each interval. The configuration efficiency is extremely low, and it is difficult to guarantee the correctness of configuration. redone
