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 accompanying drawings and specific embodiments.

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

[0034] 1) Model extraction: model extraction is carried out aiming at the actual functions of DER equipment components to form the required LN.

[0035] 2) Model construction: perform model construction based on the extracted LNs to form an XML model file of the DER device.

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

[0037] 4) Model identification: IED parses the target file to realize automatic identification of DER equipment models. When the DER equipment is working, the IED analyzes the collected data of the DER equipment, ...

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 modeling of power system components, in particular to a method for realizing modeling of distributed power generation equipment based on the IEC 61850-7-420 standard. Background technique [0002] In recent years, with the increasingly prominent energy crisis, 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 the equipment, and the types of communication interfaces are different, which will make the system extremely limited in terms of information integration, operation control, and scheduling management. big constraints. Internationally, the power sector, operators and distributed generation manufacturers realize that a unified intern...
