Description

Technical Field

[0002] During the smart substation transformation process, it is crucial to ensure that the substation's power supply reliability is not affected. Cross-bay equipment, such as busbar protection devices, must be fully operational. The challenge of integrating new equipment without disrupting operational equipment is a crucial issue. The paper "Application of a Universal Interface Conversion Device in the Intelligent Transformation of Busbar Protection in Conventional Substations" proposes a substation transformation solution based on a universal interface conversion device. This device addresses the issue of simultaneously integrating digital busbar protection devices into both conventional bay equipment and the transformed digital bay equipment during substation transformation, and has become a universal solution for digital substation transformation.

[0003] Currently, early digital stations are gradually reaching the end of their transformation period. Due to the inconsistency of the GOOSE data sets sent by the relevant secondary equipment before and after the transformation, in order to complete the intelligent transformation of the digital station, the conversion device should be able to achieve two-way conversion of the GOOSE messages of the relevant secondary equipment before and after the transformation: receiving the GOOSE messages of the secondary equipment before the transformation, organizing the content of the GOOSE data set according to the GOOSE transmission data set of the transformed equipment and sending the GOOSE message; receiving the GOOSE messages of the transformed equipment, organizing the content of the GOOSE transmission data set according to the GOOSE transmission data set of the equipment before the transformation and sending the GOOSE message. Currently, mature conversion devices are available and are applied in intelligent station transformation projects, but the process layer configuration text of the conversion device needs to be manually written, which is labor-intensive and difficult to ensure correctness. This increases the workload of the intelligent transformation of substations and reduces the efficiency and quality of the transformation. Summary of the Invention

[0044] The technical solutions and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] by Figure 1 Taking the application scenario as an example, the conversion device needs to receive the GOOSE message of the busbar protection before the transformation, and virtualize the busbar protection after the transformation according to the GOOSE message format of the busbar protection after the transformation, communicate with each intelligent terminal after the transformation, and realize the function of the busbar protection before the transformation tripping the intelligent terminal after the transformation; it needs to receive the GOOSE message of each line protection after the transformation, and virtualize the line protection before the transformation according to the GOOSE message format of the line protection before the transformation, communicate with the busbar protection before the transformation, and realize the function of the line protection after the transformation starting the busbar protection failure before the transformation.

[0046] against Figure 1 This embodiment provides a method for configuring a conversion device for use in smart substation transformation. Figure 2 As shown, the specific steps include:

[0047] Step 1: Set the GOOSE input virtual terminals for receiving the output signals of the secondary equipment before and after the conversion for the ICD (IED capability description file) model of the conversion device. The two types of input virtual terminals are associated with the short addresses of the input signals to be converted and the short addresses of the output signals after conversion respectively:

[0048] 1) The conversion device needs to be configured with a "jump line X" input virtual terminal for receiving the bus protection signal before the transformation, and associated with the corresponding input signal short address; configured with a "jump line X_out" input virtual terminal for receiving the bus protection signal after the transformation, and associated with the short address of the output signal converted from the above input signal;

[0049] 2) It is necessary to configure the "Line X-Start A / B / C Phase Failure" input virtual terminal to receive the line protection signal after the transformation and associate it with the corresponding input signal short address; configure the "Line X-Start A / B / C Phase Failure_out" input virtual terminal to receive the line protection signal before the transformation and associate it with the short address converted from the above input signal to the output signal.

[0050] Step 2: Use the SCD (full station system configuration file) configuration tool to connect the output signals of the ICD models of the secondary equipment before and after conversion to the relevant GOOSE input virtual terminals of the conversion device, export the CCD configuration file of the conversion device (loop instance configuration file), and download it to the conversion device:

[0051] 1) Import the SCD file before the transformation, connect the "Jump Line X" output virtual terminal of the busbar protection signal before the transformation to the "Jump Line X" input virtual terminal of the conversion device, connect the "Start A / B / C Phase Failure" output virtual terminal of the line protection signal of line X before the transformation to the "Line X-Start A / B / C Phase Failure_out" input virtual terminal of the conversion device, and export CCD configuration file 1;

[0052] 2) Import the modified SCD file, connect the "Jump Line X" output virtual terminal of the modified busbar protection signal to the "Jump Line X_out" input virtual terminal of the conversion device, connect the "Start A / B / C Phase Failure" output virtual terminal of the line protection signal of the modified line X to the "Line X-Start A / B / C Phase Failure" input virtual terminal of the conversion device, and export CCD configuration file 2;

[0053] 3) Download CCD profile 1 and CCD profile 2 to the conversion device.

[0054] Step 3: Perform secondary processing on the CCD configuration file in the conversion device. The signal link information of the secondary equipment before the conversion remains unchanged, and the signal link of the secondary equipment after the conversion is changed from input control block information to output control block information. Taking the conversion of the line protection start failure signal after the transformation to the line protection start failure signal before the transformation as an example, the following is the line protection start failure control block information of line 1 before the transformation:

[0055]

[0056]

[0057] Perform secondary processing on the CCD configuration file in the conversion device. The signal link control block of the secondary device after the connection conversion needs to be changed from the GOOSESUB element to the GOOSEPUB element. For the virtual terminals that need to be converted, delete the intAddr element and modify the name of the DAI element according to the virtual terminal daName. For the virtual terminals that do not need to be converted, add the DAI element, fill in the name with the virtual terminal daName, and fill in the sAddr with the signal short address of the corresponding data type. The modified control block information is as follows:

[0058]

[0059]
