Embodiment 1

[0049] see figure 1 , figure 1 It is a flow chart of a secondary circuit configuration control method of a smart substation disclosed in the embodiment of the present application.

[0050] Such as figure 1 As shown, the method includes:

[0051] Step 101: Obtain the current version of the substation configuration description file SCD (Substation Configuration Description) file;

[0052] Specifically, the system configuration tool is responsible for configuring the current version of the substation configuration description file SCD file.

[0053] Step 102: compare with the SCD file of the previous version stored in advance, and obtain the comparison result;

[0054] Specifically, the previous version of the SCD file may be pre-stored, and after the current version of the SCD file is obtained, the information of two different versions of the SCD file is compared.

[0055] Step 103: Generate a configuration upgrade report according to the comparison result, and the configur...

Embodiment 2

[0063] see figure 2 , figure 2 It is a flow chart of another intelligent substation secondary circuit configuration control method disclosed in the embodiment of the present application.

[0064] On the basis of Embodiment 1, this embodiment further adds step 105: displaying the secondary circuit configuration information in the current version of the SCD file in a graphical manner.

[0065] By fully displaying the original "invisible and intangible" secondary virtual circuit configuration information, it is more convenient for staff to view the secondary circuit configuration upgrade range and configuration information change details.

[0066] It should be noted that the secondary circuit configuration information may include multiple secondary circuit virtual terminals and connection relationships among the multiple virtual terminals. When displaying graphics, the secondary circuit shall be displayed in accordance with the requirements of the relay protection profession....

Embodiment 3

[0071] see image 3 , image 3 It is a flow chart of another intelligent substation secondary circuit configuration control method disclosed in the embodiment of the present application.

[0072] On the basis of the previous embodiment, this embodiment further adds:

[0073] Step 106: Obtain the virtual circuit configuration CRC code of each IED;

[0074] Step 107: Extract the virtual circuit configuration CRC code in the SCD file of the current version;

[0075] Step 108: comparing the virtual circuit configuration CRC code of each of the IEDs with the virtual circuit configuration CRC code in the current version of the SCD file, and performing CRC code verification;

[0076] Step 109: When the verification result of the CRC code is different, an alarm signal is sent.

[0077] In this embodiment, a comprehensive verification method combining virtual circuit configuration CRC code verification and information comparison is proposed. By verifying the CRC code of the IED dev...

Abstract

The invention discloses a secondary circuit configuration controlling method and system for an intelligent substation. The method comprises a present version of SCD (Substation Configuration Description) file is obtained; the present version of SCD file is compared with a prestored last version of SCD file; a configuration update report which includes the IED (Intelligent Electronic Device) update range is generated; and according to the configuration update report, an information comparison report which includes details of configuration information change is generated for each IED requiring configuration update. According to the invention, the configuration update report defines the IED update range, and the information comparison report describes the details of configuration information change of each IED which requires configuration update, thereby effectively helping professional staff of relay protection to safely and efficiently carry out daily maintenance on secondary circuits of the intelligent substations.

Description

technical field [0001] The present application relates to the technical field of smart grid, and more specifically, relates to a method and system for configuring and controlling a secondary circuit of a smart substation. Background technique [0002] In recent years, my country's smart grid has entered a comprehensive construction stage, and infrastructure substations have been constructed in accordance with smart substation standards. However, the problems encountered in the operation and maintenance of smart substations have seriously affected the promotion and application of smart substations. These problems related to factors such as secondary circuit configuration, control and experimentation endanger the safety and stability of the relay protection system. For example, there is a lack of management methods for the SCD (Substation Configuration Description) version of the smart substation configuration description file, the scope of influence of the SCD file upgrade c...
