Problems solved by technology

The former method is inefficient and error-prone, and the latter method is not flexible enough. When two data locations change, the device configuration will not be changed, nor will it affect the operation of the device. The degree of visualization in both ways is relatively low

Embodiment Construction

[0027] The IEC61850 dual-model verification technology is characterized in that it comprises the following steps:

[0028] Step 1. Select the model file stored locally;

[0029] The model file here can be an SCD file, a CID file, or an XML file, as long as the model file meets the requirements of IEC61850.

[0030] Step 2. Count the IED information in the model file, and select an IED to be checked and an access point belonging to it;

[0031] Obtain the content of the model file by reading and writing the file, including the IED name and the collection of access points used by each IED, and use the XML parsing function of the Qt library to extract the model file IED and AccessPoint.

[0032] Step 3, configure the information of the MMS server to be connected, including IP address and port number;

[0033] The MMS server is the device running online. The local configuration file stores the IP address and port number of the device running online. When testing different device...

Abstract

The invention relates to a checking method of model information of intelligent electronic device configuration of IEC61850 standard intelligent substations. The type of a model file is not limited to the SCD file; comparison information comprises data names, data types and data values; which data are modified by an operation model can be detected; whether the values of the data are changed compared with the original values is detected; whether the model configuration downloaded to a device is constant with the model configuration imported to background is detected; whether to generate a persistent file is determined by a user; the format is flexible and is selected by the user according to a need; a user interface is simple and visualized and is simple in operation and high in visualization degree.

Description

technical field [0001] The invention relates to the detection field of intelligent substations using the IEC61850 standard, and in particular relates to the verification of model information configured by intelligent electronic devices in intelligent substations. Background technique [0002] With the rapid promotion and application of the IEC61850 standard in my country's power industry, smart substations have entered a stage of rapid development. Operations such as equipment replacement, equipment maintenance, and model replacement will occur. During this process, the substation configuration description file, that is, the SCD file, will also change. In order to ensure the normal operation of the equipment, it is necessary to ensure that the configuration information of the intelligent electronic device and the configuration information of the SCD file Consistent, but some manufacturers may modify the CID file in order to pass the acceptance. In this case, it is difficult to...
