Graphical and rdf model building method for smart substation design

Abstract

The invention provides a method for constructing a figure and an RDF (Radio Direction Finder) model for designing an intelligent transformer substation. The method provided by the invention comprises the following steps of: utilizing the RDF to describe an IEC61850 model through utilizing the same form of an IEC61970CIM (Computer Integrated Manufacturing) to obtain an RDFSchema of the IEC61850 model for assuring the structure of the IEC61850 model object. The structure of the IEC61850 model object comprises model types, mode type attributes and incidence relations between the model types. By utilizing the method to design model types of the intelligent device and virtual terminals and a design tool of a graphics primitive development secondary system, the engineering design of the secondary system of the intelligent transformer substation can go deep into a logical layer so that an interoperable relation of logical functions can be described by means of imaging and the design assignment of the intelligent transformer substation can be smoothly processed. The model of a primary system is described by utilizing the IEC61970-CIM model so that the compatibility and the interoperability between the model and the primary system model data utilized by a dispatching mechanism can be realized.

Description

technical field [0001] The invention relates to a graph and RDF model building method for intelligent substation design. Background technique [0002] With the proposal of building a strong smart grid development plan, smart grid construction will be the core goal of the development of the power industry. Among them, the smart substation is an important node in the smart grid. Compared with conventional substations, smart substations (including digital substations) have undergone fundamental changes in their communication structure and operating form by using network communication technology and layered information processing technology. In a conventional substation, due to the one-to-one mapping relationship between the physical wiring of the secondary circuit and the logical signal, the functional configuration of the substation and the input-output relationship of information or signals between functions can be reflected through the secondary circuit wiring.

Problems solved by technology

Therefore, it is difficult to guarantee the accuracy of the model information. As a result, a large number of research and development personnel must participate in the engineering construction phase of the smart substation, agree on the functional communication configuration at the logical level, and constantly modify the software code and repeatedly debug on site. , the construction process is very irregular and the cycle is very long, which greatly increases the difficulty and cost of substation construction
