Description

Technical Field

[0001] The present invention relates to the technical field of substation design, and in particular to a method and system for automatically generating a substation system configuration description file. Background Art

[0002] In the previous design of smart substations, the design of real circuits and virtual circuits was separate, and the delivery documents were real circuit blueprints and virtual terminal tables, and the delivery results were not structured documents. The SCD model contains the tripping information of all optical cable circuits on site and the alarm transmission of all signals. It is an indispensable file for the integration and commissioning of the substation secondary system. At present, the commissioning personnel usually integrate and configure the SCD files on site. During the integration and configuration, there is a lot of manual configuration work, which affects the overall progress of the secondary system commissioning and acceptance.

[0003] The SCD file is integrated and configured, mainly including the ICD model corresponding to all IED devices involved in the integration project, extracting the descriptive information such as the instantiation of the drawing input and output, querying the relevant network configuration diagram, and manually configuring the SCD file communication subnet. At the same time, it is necessary to supplement the optical cable information in the SCD file according to the direction of the optical cable. The above SCD file integration is time-consuming and laborious, and a considerable part of the work already has a data basis in the blueprint issued by the design institute, and there is a certain regularity. At present, with the release of the industry standard "DL / T 2765-2024 Specification for Logical Model of Transmission and Transformation Engineering", the secondary physical circuit information originally carried by CAD\PDF drawings is converted into a physical circuit logical model (ie, SPD model). The SPD model has a complete description of the physical circuit, and the SPD model also contains a complete mapping association with the substation system configuration description model (SCD model).

[0004] Currently, there is no relevant technology for automatic generation of SCD files. In the engineering application of SCD files, in addition to virtual terminal configuration, there are also time-consuming and labor-intensive tasks such as instantiation description update, IED device integration, communication subnet configuration, and optical cable information configuration.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. The embodiments of the present invention and the technical features in the embodiments may be combined with each other unless there is a conflict.

[0019] The term "and / or" is only a description of the association relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " generally indicates that the related objects are in an "or" relationship.

[0020] Example 1

[0021] like Figure 1 As shown, this embodiment introduces a method for automatically generating a substation system configuration description file, which specifically includes the following steps: Step 1: Before the method is executed, the physical loop logic (Substation Physical Description File, SPD) model and the substation system configuration description (Substation Configuration Description, SCD) model of the substation system configuration description file are pre-established. The SPD model has a complete description of the physical loop, and the SPD model also contains a complete mapping association with the SCD model.

[0022] Step 2: extract the first intelligent electronic device (IED) in the SPD model, read the capability description (IED Configuration Description, ICD) model of the first IED device, update the first IED device to obtain the second IED device, and write the second IED device into the SCD model, specifically: (1) Create or import an SCD model: For new projects, create a new SCD model; for renovation projects, the designer imports the existing SCD model for update.

[0023] (2) Extract all elements of the first IED device whose instantiation name (IedName) attribute is not empty in the SPD model, read the ICD model reference address of the first IED device, and load the ICD model file of the corresponding address.

[0024] (3) Calculate the checksum of the ICD model and write it into the element of the first IED device.

[0025] (4) Update the element of the first IED device in the ICD model: read the Name attribute of the first IED device in the SPD model, modify the Name attribute of the element of the corresponding second IED device in the SCD model, and update the IedName attribute of its communication subnet node.

[0026] (5) Writing the elements of the IED device into the SCD model: Reading the ICD model associated with the first IED device in the SPD model, updating the elements of the second IED device through the above steps, and writing the elements of the second IED device into the SCD model.

[0027] (6) Handling data type template conflicts: Compare the data templates in the ICD model and the SCD model. For data templates of the same type, compare their attributes and sub-elements. If they are inconsistent, add a suffix to the data type template in the ICD model and rename it to ensure that there is no conflict with the data template in the SCD model.

[0028] Step 3: Analyze the communication cable topology of the SPD model, extract the communication information of the ICD model, and generate the communication subnet of the SCD model according to the preset communication subnet rule template of the SCD model and the communication information of the ICD model, specifically: First, parse the communication cable topology of the SPD model, read all the network cables and optical cable connection information of the SPD model, obtain the network structure topology, and determine the substation network topology type based on the network structure topology. That is, extract all the Cable information of the SPD model. When the type of the Cable element is NetworkCable, it represents the network cable, and by traversing the network port connection information of the device, it determines whether the network status is a single network or a dual network; when the type of the Cable element is Fiber, it represents the optical cable, and by traversing the optical port connection information of the device, it determines the number and connection mode of the process layer network.

[0029] Secondly, before implementing the configuration of the communication subnet, it is necessary to pre-establish the communication subnet rule template, which includes single and double networks, IED sorting (interval, voltage level, etc.), station control layer IP range, multicast address configuration logic, process layer network quantity and other rules. Some configuration rules are as follows: (1) Station control layer IP configuration: The IPs under the same communication subnet are configured from network A to network B. Network A is filled in from 192.168.100.1 and network B is filled in from 192.168.101.1. The default value of the subnet mask is 255.255.255.0.

[0030] (2) Mac address configuration: By default, the Mac address of network A is filled in from 01-0C-CD-01-00-01 downwards, and the Mac address of network B is filled in from 01-0C-CD-01-01-01 downwards.

[0031] (3) AppId configuration: By default, the last two digits of the Mac address are combined into the AppId or sorted in sequence from 00 to 01.

[0032] Other configuration rules are not described here.

[0033] Finally, configure the communication subnet according to the preset rule template. The steps are as follows: (1) Determine the type of IED device. The types of IED devices are distinguished in the following ways: IED devices without LDevice nodes are station control layer devices; IED devices with LDevice nodes and report control blocks are bay layer devices; IED devices with LDevice nodes but no report control blocks and with GSEControl nodes or SampledValueControl nodes are process layer devices.

[0034] (2) According to the network topology type of the substation system, the communication subnet information of the ICD model is merged, and the communication subnet information of the merged ICD model is written into the communication subnet of the SCD model; according to the preset communication subnet rule template of the SCD model, nodes of the corresponding network topology type are established in the SCD model to generate the communication subnet of the SCD model, and the communication subnet of the SCD model includes the MMS network, the Goose network, and the SV network.

[0035] (3) Set the MMS network information: Add the "Address" node, "GSE" node, "SMV" node and related PhysConn nodes of all the second IED devices in the bay layer with SubNetWork type 8-MMS and ConnectedAP node name "S*" to the station control layer communication subnet in the SCD model according to the IED device sequence preset in the rule template, and set all station control layer addresses according to the preset IP range and physical address mapping rules; if it is a dual network, copy the information of network A to network B, and reset the IP address and physical address of network B according to the preset rules.

[0036] (4) Set the Goose network and SV network information: Add the "GSE" nodes and related PhysConn of all process layer second IED devices with SubNetWork type of GOOSE and ConnectedAP node name of "G*" to the communication subnet; add the "SMV" nodes and related PhysConn of all IED devices with SubNetWork type of SMV and ConnectedAP node name of "S*" to the communication subnet; then set the relevant information of all nodes according to the preset multicast address and AppId setting rules.

[0037] (5) The access point of the process layer switch is special. The ConnectedAP node does not contain any SMV nodes or GSE nodes. Therefore, the PhysConn port information of the switch cannot be added to the corresponding subnet. Figure 4 As shown, according to the mapping association between the SCD model and the SPD model, the physical device port connected to the switch port is found, and then according to the IED model port mapped to the physical port of the device, the network where the port is located can be obtained, and then the port can be added to the network.

[0038] Step 4: Import the preset virtual terminal connection table into the SCD model to generate virtual terminal connection information, parse the hard connection reference relationship of the virtual terminal in the SCD model in the SPD model, and update the instantiation description information of the SCD model, specifically: First, this embodiment collects the virtual terminal connection table designed and delivered by the design unit, such as Figure 2 The virtual terminal connection table includes the starting point device name, starting point IEDName, starting point reference address, starting point function name, signal direction, end point device name, end point IEDName, end point reference address, end point device name and other attributes.

[0039] Secondly, parse the virtual terminal connection table and write the virtual terminal connection information into the SCD model. Read the information of the starting point and end point ICD models in the virtual terminal connection table, search in the corresponding ICD model according to the "LD / LN.DO.DA" format, and finally locate the DO or DA elements corresponding to the virtual terminal connection starting point and virtual terminal connection end point.

[0040] In a specific embodiment, for a certain IED device, the GOOSE network input and SV network input received by it are first traversed, and then the IedName, ldInst, InClass and other information contained in the external connection point of the IED device are extracted, and then combined with the IedName, InAddr and other information of its own internal connection point to form the virtual terminal connection information in the SCL language format, which is added to the "Inputs" node under LN0 of the corresponding LD of the corresponding IED device in the SCD model to form a virtual terminal connection in the SCD model.

[0041] Finally, instantiate and update the SCD description information to construct Figure 4 The virtual-real correspondence between the SPD model and the SCD model is shown in the figure. The reference address corresponding to the connection starting point of the virtual terminal of the SCD model is searched, and the corresponding component is determined in the SPD model. According to the description information of the physical connection point of the device connected to the component, the description information of the corresponding virtual terminal in the SCD model is updated. The signal transmission is carried out according to Figure 3 There are two main ways to transmit. First, define the hard node signal of the SPD model. One is to directly define the signal through the DA element of the process layer virtual terminal connection point in the IED device of the measurement and control device and transmit it to the station control layer, thereby assisting the background monitoring signal alarm; the other is to transmit it to the DA element of the process layer virtual terminal connection point, and then the DA element of the process layer virtual terminal connection point continues to transmit it backward according to the virtual connection definition signal.

[0042] Step 5: Analyze the optical cable topology of the SPD model and update the optical cable connection information of the SCD model, specifically: In the intelligent station, the optical ports of the second IED device at the process layer and the second IED device at the bay layer are interconnected through optical fibers, and information interaction is completed with the help of virtual terminal mapping. In the SCD model, it is necessary to clearly define the port of the virtual circuit accessing the second IED device, and record the information of the second IED device on the opposite side of each port of the second IED device and the identification of the connected optical cable.

[0043] First, parse all the optical cable topology connection information in the SPD model to obtain the optical cable connection relationship between the first IED device, then retrieve the icdPort attribute of the optical fiber physical port element, and obtain the associated port number in the SCD model. Based on the starting and ending information of the virtual terminal connection in the SCD model, match the corresponding optical cable physical loop connection topology in the SCD model, and finally parse the information from the starting port to the ending port of the second IED device connected by the virtual terminal in the SCD model.

[0044] The icdRef attribute of the optical fiber physical port element is associated with the port number in the SCD model, which is expressed as "board number-port number", such as "7-A". The port number in the SCD model connects the virtual loop of the SCD model, the physcon port in the SCD model, the physical optical port element in the SPD model, and all the information of the optical cable in the SPD model, thus realizing the interaction between the optical fiber physical loop and the SCD model.

[0045] In this embodiment, for the optical cable information of a certain IED device, for the Physcon optical port in each device IED device, the real loop is traversed through the mapping relationship, the real loop connection information is written under the Communication node of the SCD model, and the Cable tag is updated. The update format of Cable is "starting point IEDName:Port_end point IEDName:Port".

[0046] Finally, configure the ports connected to the virtual terminals in the SCD model. Traverse the input and output of the virtual terminals in the SCD model, obtain the elements and DO nodes of the second IED device mapped by the virtual connection of the SCD model, and associate them with the real loop of the SPD model through the SCD model. According to the real loop fiber connection relationship, obtain the port information in the SCD model associated with the physical port element information connected to the device, and write the port information to the Extref virtual terminal connection in Inputs in batches according to the data set to complete the optical port setting. The format of the write is "port number: reference address". When multiple port numbers are associated, use " / " to distinguish, such as port number 1 / port number 2: reference address.

[0047] Based on the above steps, the second IED device is written into the SCD model, the SCD model communication subnet is constructed, the SCD model virtual terminal instantiation signal is updated, and the SCD model optical cable and port connection information is updated. Then, according to the model structure specified in DLT / 860, the SCD model information containing complete information is output, and the substation system description file is generated according to the second IED device, communication subnet, instantiation description information and optical cable connection information in the SCD model.
