Problems solved by technology
[0005] (1) The application-specific CIM model of the fixed version can only run in the fixed version of the CIM model
[0006] (2) After modifying the CIM model, the connection path will change, and the application needs to be manually corrected
[0007] (3) After the version upgrade of the CIM model, a large number of manual correction operations are required

Embodiment
[0030] see figure 1 , this embodiment provides a CIM model path query method, which is applicable to different versions of CIM models, and its main steps and working principles are as follows:
[0031] Step 101: According to the CIM model and the user's request, randomly select two CIM classes, and determine the start class and the end class.
[0032] In this embodiment, according to the CIM model used by the user, two CIM classes to be selected for connection path query through the user request can be selected arbitrarily according to the CIM model, as long as the classes described in the CIM model can be selected, The two classes selected can be the same. While selecting, make sure one of them is the starting class and the other is the ending class.
[0033] Step 102: Analyze the inheritance relationship between the start class and the end class, and obtain the start class and its inherited base class, as well as the end class and its inherited base class.
[0034] In thi...

The invention relates to the technical field of electric power engineering and discloses a CIM (common information model) path inquiring method and a CIM path inquiring device. The method mainly includes according to a CIM and a user request, arbitrarily selecting two CIM classes, and determining a starting class and a stopping class; analyzing an inheritance relationship of the starting class and the stopping class, and acquiring the starting class and a base class inherited by the same as well as the stopping class and a base class inherited by the same; according to an association relationship between the starting class as well as the base class thereof and the stopping class as well as the base class thereof, analyzing communication paths between the starting class and the stopping class; according to analysis results, sorting out the communication paths between the starting class and the stopping class, and ordering the communication paths according to path length for the convenience of a user to inquire and use. The inquiring method is suitable for CIMs of different versions, and the communication paths can be automatically generated according to modified or upgraded CIMs after the CIMs are changed or upgraded, so that a lot of manual correction or amendment operation is reduced, and working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a method and device for inquiring about a path of a CIM model. Background technique [0002] The IEC61970 series standards provide the common information model (CIM) and interface specifications. The IEC61968 series standards expand the common information model (CIM). The IEC61970 / IEC61968 series standards are important standards in the field of power system management and information exchange. The public information model (CIM) defines the semantics of information exchange in power systems, provides an effective way to exchange information and share data between different power systems, and is an important means to solve the problem of "information islands" in power systems. [0003] There are many business systems in electric power applications, and information sharing among various business systems is the key to realizing electric power informatization and i...
