Automatic modeling method of intelligent transformer substation spacer

Abstract

The invention discloses an automatic modeling method of an intelligent transformer substation spacer. The automatic modeling method comprises the following steps of: setting a mapping rule of a function model and an IEC61850 model of a device; completing the automatic mapping of a function signal model and an IEC61850 signal model of the device, and exporting a device capacity description file; and applying the device capacity description file to system configuration of a transformer substation project. In the automatic modeling method of the intelligent transformer substation spacer, the mapping rule is preset according to a PLC (programmable logic controller) logic model of the device and the signal application characteristics of the PLC logic model, and then the PLC logic model and theIEC 61850 model are mapped, that is to say, mode mapping can be completed only through instantiation of the mapping rule in the development stage of the device; and when the device is configured, signals can be classified according to functions and automatically mapped to associated function data sets simultaneously.

Description

technical field [0001] The invention relates to a method in the technical field of power systems, in particular to an automatic modeling method for an intelligent substation spacer. Background technique [0002] With the construction of smart substations, the IEC61850 standard is used as a standard protocol for engineering implementation; and how to model is the core element of the IEC61850 communication standard, and the device configuration tool is naturally mentioned as a comparison in the process of building smart substations. important position. The development of the device function depends on the configuration tool, through which the development of the internal function of the device and the external signal of the device are completed; and the important bridge between the internal function of the communication device and the external signal is the mapping process between the device function model and the IEC61850 model. China's electric power industry standard "IEC61...

Problems solved by technology

[0004] This technology eliminates most of the manual configuration work in the original project implementation, but it has its shortcomings: 1) Differentiate the instantiation process of different models through keywords, and lack of management on how to map different functional models with the IEC61850 communication model Mechanism, that is, when the same functional model is instantiated in different device projects, more repetitive model mapping work will be generated; 2) The design method of tightly coupling the short address and IEC61850 will cause the change of the internal function of the device to directly affect the device External characteristic capability description file, which may lead to repeated process of engineering system configuration

3) The repetitiveness of the engineering implementation process, because the changes required by the engineering implementation may require additional signal or model processing, this method cannot handle the "incremental" process in the engineering implementation
