Problems solved by technology

However, only a small number of objects are modeled, and the model adopted does not conform to international standards, and cannot solve the problem of edge-to-edge real-time communication
[0004] Most of my country's power distribution automation relies on centralized master stations, and has not truly realized local distributed intelligent applications; at present, it is impossible to realize side-to-side real-time and reliable communication; terminal equipment cannot support advanced functions such as self-description, plug and play; cannot support Multi-class, polymorphic data; poor interoperability between terminal devices

Embodiment 1

[0036] A plug-and-play implementation method for a device based on the IEC 61850 / IEC CIM standard model of the present invention, the method comprises the following steps:

[0037] (1) Establish a terminal model based on the IEC 61850 / IEC CIM standard model, which defines a complete and independent model architecture from the master station to the terminal equipment, which can support the self-description and self-identification of the terminal. The self-describing models of the terminal model include: (1) feeder group topology m, feeder graphic model; (2) association model of all primary equipment and secondary equipment in the feeder group; (3) single IED secondary equipment configuration model. Terminal function description, including remote signaling, remote control, measurement, wave recording, and various protection functions. The above models can support applications such as plug-and-play, distributed energy management, and equipment status monitoring.

[0038] (2) Dep...

Embodiment 2

[0048] Before IED1 is connected to this feeder group, the production configuration is completed and a self-describing model is generated. Self-describing models include:

[0049] (1) Feeder group topology file, graphic file;

[0050] (2) Associated files of all primary equipment and secondary equipment of the feeder group:

Abstract

The invention relates to a plug-and-play implementation method for devices based on the IEC 61850 / IEC CIM standard model, comprising the following steps: (1) establishing a terminal model based on the IEC 61850 / IEC CIM standard model; (2) using object-oriented equipment The model is mapped to the communication protocol of the Industrial Internet of Things; (3) The IoT front-end unit integrates the CIM model on the main station side with the 61850 model on the terminal side; (4) The above terminals are automatically identified and configured by the main station and the terminals in the same feeder group ; (5) The terminal automatically synchronizes the model of the master station after the change, and recognizes the change and updates the configuration; (6) The front-end informs the master station and all terminals of the configuration result; (7) The terminal is controlled by the master station and the terminals in the same feeder group Identify each other and realize real-time data interaction. This method establishes a terminal standard model, establishes a communication protocol that supports edge-cloud and edge-edge, realizes terminal self-description and terminal plug-and-play, realizes real-time data interaction under the edge-edge communication network, and provides on-site FA. Valid data support.

Description

technical field [0001] The invention belongs to the technical field of medium and low voltage power distribution, and relates to a method for realizing plug and play for medium and low voltage distribution network devices, in particular to a method for realizing plug and play of power distribution terminals based on the IEC 61850 / IEC CIM standard model . Background technique [0002] IEC CIM includes three components of IEC 61970 / 61968 / 62325. CIM is not only a series of standards, but also a solution. IEC CIM provides a power model to meet the needs of power system application integration. IEC 61850 is by far the most complete international communication standard for substation automation. With the development of secondary side distribution automation equipment and systems, equipment integration and information integration have become an inevitable trend, and a unified information platform is urgently needed to realize the entire automation system. Unify substation commun...
