Embodiment Construction

[0026] figure 1 Schematic diagram of the data processing flow for the shared modeling approach for smart substations and master stations. Such as figure 1 As shown, the private communication protocols of various manufacturers are used to obtain the substation steady state, transient state, dynamic data collected by various sensors, equipment status, images and other panorama data that fully reflect the status and operating conditions of substation equipment, following the IEC 61850 construction According to the model rules, the panorama data is converted into an object model that conforms to the IEC 61850 standard; according to the global unified naming rules for resources, under the definition of unified semantics, the SCL (substation configuration description language) of substation secondary equipment (protection, measurement and control equipment, etc.) ) model and the grid CIM (common information model) of primary equipment (substations, lines, loads, etc.) The primary ...

Abstract

The invention relates to a sharing modeling method of an intelligent substation and a primary station. In the method, panoramic data are converted into an object model in accordance with IEC 61850 standards by acquiring panoramic data which comprehensively reflect equipment states and operating states of the substation such as substation steady states, temporary states, dynamic data, equipment states, images and the like acquired by various sensors; a primary station primary equipment model in accordance with a substation secondary equipment model of IEC 61850SCL and IEC 61970CIM modeling standards carries out mutual conversion mapping to realize unified modeling of primary equipment and secondary equipment of an electric power system; and a GID open application program interface in accordance with IEC 61970GID standards is provided. With the method, the substation unifies and simplifies a data source of the substation to form unique basic information based on the same section; and the interaction of internal information and external information of the substation is realized by unifying standard modeling; the seamless sharing of plant station information of the intelligent substation and an automation system of the primary station are realized; and the information of a primary station terminal and a plant station terminal for scheduling is free from maintenance. The method is suitable for sharing modeling of the intelligent substation and the primary station.

Description

technical field [0001] The invention relates to a foreign-related intelligent substation and a master station shared modeling method, which belongs to the technical field of power system automation. Background technique [0002] The smart grid clearly states the need to realize the organic integration of power flow, information flow, and business flow. As a grid node, the substation first needs to supplement, improve and standardize the three streams of information to meet the real-time needs of various clients of the smart grid. The substation will also have the organic integration of power flow, information flow, and business flow. Therefore, for smart grids, the most important thing for smart substations is to supplement, improve, and standardize the power flow, information flow, and business flow information required by smart grids for access by various clients of smart grids. To this end, it is first necessary to realize unified management and modeling of all data in t...
