Chinese patent CN 101706773A proposes the use of XML information reorganization to realize rapid and automatic modeling of substations, which is applied to digital substations using IEC 61850 communication and the modeling of intelligent electronic devices (Intelligent Electronic Devices, IEDs) in traditional substations, but SAddr must be agreed in advance Information format, poor versatility
The above research has not yet involved DER equipment modeling. In order to conveniently and quickly model DER equipment and reduce the difficulty of system integration, this invention proposes a DER equipment modeling implementation method based on the IEC61850-7-420 standard to promote DER equipment. Standardized application of communication and control interfaces

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0033] figure 1 Describes the DER equipment modeling process of the present invention, which is divided into model extraction, model construction, download and identification according to the order of realization:

[0034] 1) Model extraction: Model extraction is based on the actual functions of DER equipment components to form the required LN.

[0035] 2) Model construction: Model construction based on each extracted LN to form an XML model file of DER equipment.

[0036] 3) Model download: Generate a target file based on the XML model file and download it to the corresponding IED of the DER device.

[0037] 4) Model recognition: IED parses the target file to realize automatic recognition of DER equipment model. When the DER equipment is working, the IED analyzes the collected data of the DER equipment, establishes information communication with the management cent...

Abstract

The invention relates to an international electrotechnical commission (IEC) 61850-7-420 standard-based distributed generating equipment modeling implementation method. The method comprises the following processes of extracting, building, downloading and identifying a generating equipment model and the like. By the method provided by the invention, flexible and quick modeling can be performed on the distributed generating equipment; the technical problem of the standardization of communication and a control interface of the distributed generating equipment is solved, and the normalization and the standardization of information interaction between the distributed generating equipment and a system are promoted.

Description

Technical field [0001] The invention relates to a method for realizing power system component modeling, in particular to a method for realizing distributed power generation equipment modeling based on the IEC 61850-7-420 standard. Background technique [0002] In recent years, as the energy crisis has become increasingly prominent, the field of clean and renewable energy has received widespread attention. In the future, more and more distributed energy resources (DER) will be connected to the grid. At present, most manufacturers of DER and other system components (such as monitoring, protection devices, etc.) customize the communication protocols of their equipment, and the types of communication interfaces are different. This will make the system extremely vulnerable to information integration, operation control, and dispatch management. Big constraints. Internationally, power departments, operators, and distributed generation manufacturers realize that a unified international ...
