Description

Protection application topology identification is the premise and basis for realizing site-based fast line protection.

[0047] Embodiment 1, please refer to Figure 1 , Figure 1This is a flowchart of the first embodiment of a method for generating a protection application topology according to the present invention, including:

[0048] Step S101, obtaining the full-station system configuration data of the distribution network and the multi-loop power supply data of the distribution network;

[0055] In a method for generating a protection application topology provided by an embodiment of the present invention, by obtaining the full-station system configuration data of the distribution network and the multi-loop power supply data of the distribution network, extracting the conductive device information from the full-station system configuration data, the conductive device information is used to establish a conductive device information table, constructing device connection relationship tree structure data according to the device connection relationship in the conductive device information, and generating protection application topology information based on the device connection relationship tree structure data and in combination with the multi-loop power supply data of the distribution network. Through a method for generating a protection application topology, the technical problem that the existing method for generating a protection application topology is time-consuming and laborious and difficult to meet the requirements of a large-scale topology is solved, and the generation efficiency of the protection application topology is improved.

[0056] Example 2, please refer to Figure 2 , Figure 2 which is a flowchart of a method for generating a protection application topology according to the present invention, including:

[0057] Step S201: Obtain the initial full-station system configuration data of the distribution network and the multi-loop power supply data of the distribution network;

[0058] In the embodiment of the present invention, a configuration tool is used to obtain the initial full-station system configuration data of the distribution network and the multi-loop power supply data of the distribution network.

[0059] In specific implementation, a configuration tool is used to implement the mapping from the CIM model (Common Information Model) to the SCL model (Structured Control Language), complete the editing of the SCD file (substation configuration description file), map the signals in the SCD to the information body addresses of the station area protection device 104 server, and configure some parameters required for the operation of the communication board of the station area protection device. After this part of the configuration is completed, the configuration tool can export the substation-wide SCD file, the point table file with IEC 61850 mapped to the 104 communication protocol, and the custom topology configuration file. The configuration tool includes six major modules: project management, SCL editing, application configuration, drawing tool, gateway configuration, and device configuration. Among them, SCL editing realizes the import of ICD files, summarizes each ICD to synthesize the SCD file, modifies the SCD file, and displays the SCD file. The drawing tool draws the primary system model and its topology in the CIM / G format, completes the association between primary equipment and secondary functions, and imports and exports CIM / G files. The application configuration parses the SCD file into a relational database that is easy for programs to use and expands the configuration related to the 61850 model and applications. The gateway configuration can export the 104 point table mapping file config.xml, and the device configuration customizes the topology configuration file and can also export the configuration files required for different application backgrounds according to custom templates. When applied to the station area line protection of a distribution substation, if the configuration tool adopts an offline form, the operating system is Linux, the CPU is quad-core 2.8 GHz, the memory is 4G, and the hard disk is 1TB. The ICD files of each feeder terminal and the substation CIM file can be manually imported in advance, and then an SCD file containing the substation-wide topology structure, a 104 point table mapping file, and a topology configuration file are formed. Finally, by parsing the SCD file and combining the information of each terminal type in the 104 point table mapping and the scope information of the protection application topology in the topology configuration file, detailed system topology information can be obtained; if an online form is adopted, the functions of the configuration tool are integrated into the main CPU module of the station area protection device, which communicates with the distribution network master station via 104 and communicates with the feeder terminal via MQTT to realize the transmission of relevant configuration information. In this way, the ICD files of the feeder terminals and the master station CIM file can be transmitted to the station area protection device in real time, and then it is the same as the offline operation. Finally, an SCD file is formed to obtain the initial substation-wide system configuration file data (i.e., the initial substation-wide system configuration data).

[0060] Considering that the protection scope of the station area line protection of the distribution substation only includes the main lines and branch lines of some lines, and the multi-loop power supply situation in the distribution network, the multi-loop power supply data of the distribution network is obtained.

[0061] Step S202, perform information configuration and data conversion on the initial substation-wide system configuration data to obtain the substation-wide system configuration data of the distribution network;

[0062] In an embodiment of the present invention, information configuration and data conversion are performed on the obtained initial substation system configuration data to obtain the substation system configuration data of the distribution network.

[0063] In a specific implementation, by analyzing the primary system and collecting its functional requirements for secondary devices, the required IED (Engineering Document Index) types and ICD files (IED Capability Description Files) describing the functions and capabilities of various IEDs are obtained. The ICD is imported using the SCL editing module, and configurations including networks and virtual channels are completed according to requirements to generate an SCD file containing only secondary device information. The CIM model is manually or automatically imported into the drawing tool and supplemented to the substation part of the SCD. Meanwhile, the primary-secondary association relationship is recorded under the substation, and the name of the wiring topology diagram is recorded in the SCD file through a private label, and a CIM / G format graphic file can be exported. The primary and secondary information and the association relationship between the primary and secondary in the SCD form the basis for exporting the application configuration. The application configuration module parses remote control, remote signaling, and remote measurement signals from the SCD and stores them in an sqlite database as a unified data source for subsequent configurations such as remote terminal units and network gateways. The network gateway configuration and device configuration module export the configuration files required for device operation from the sqlite database.

[0064] For the conversion from CIM files to SCL model data, both the CIM model and the SCL model establish data models using an object-oriented method and use the XML language as the model description language. However, CIM uses association descriptions for the relationships between various class packages, while the description of SCL is hierarchical, and the device names are inconsistent, so a model mapping needs to be constructed.

[0065] Each feeder in the CIM file will give a cim xml file. If all cim files are transferred to a single Substation, the main diagram will be relatively large. Therefore, it is considered to use each feeder as a Substation in the SCD, create multiple Substations in the SCD, and at the same time change the cim:Substation in the CIM to bay, and establish the device mapping relationship between CIM devices and IEC61850-6 devices. The mapping relationship is shown in the following table:

[0066]

[0067]

[0068] Parse the CIM file to generate conductive equipment objects and terminal objects. Based on the connection point relationships in the terminal objects, establish the topological connections between devices. Then, convert the CIM into the Substation part in the SCD file according to the definitions in IEC61850-6 and the device mapping relationships.

[0069] The description format of Substation in SCD is that each line is regarded as a bay, and the busbar is regarded as a separate bay. The basic structure form of SCD is Substation / Substation → VoltageLevel / Voltage level → Bay / Bay → ConductingEquipment / Conductive equipment. Conductive equipment includes attributes such as LNode and Terminal. LNode is used to express the association with secondary equipment, and Terminal is associated with connectivityNode / Connection point to express the connection relationship between primary equipment.

[0070] Step S203: Extract the conductive equipment information from the whole station system configuration data; the conductive equipment information is used to establish a conductive equipment information table.

[0071] In the embodiment of the present invention, extract the conductive equipment information from the whole station system configuration data to establish a conductive equipment information table.

[0072] In a specific implementation, extract the content related to Conducting Equipment / PowerTransformer in Substation of SCD to generate a conductive equipment information list. The content generated for each parsed conductive equipment includes the following information: name, type, connection point, device name / IED name, LN list (optional). After the conductive equipment information table is generated, sequentially search in the conductive equipment table according to the starting and ending points of the line through the connection point. Finally, obtain the primary topological information of each line. When applying to the substation area line protection, the topological information table only includes conductive equipment of the switch type.

[0073] Step S204: Define the starting point of the feeder equipment in the conductive equipment information as the root node.

[0074] Step S205: Construct the tree structure data of the device connection relationship according to the device connection relationship in the conductive equipment information and the root node.

[0075] In the embodiment of the present invention, with the starting point of the feeder equipment as the root node, construct the tree structure data of the device connection relationship according to the device connection relationship in the conductive equipment information.

[0076] In a specific implementation, as can be seen from the above Substation description, in IEC61850-6, the connection relationship of primary equipment is expressed through connection points in the equipment. For interconnected equipment, the reference paths of their connection points are the same. By parsing the content related to the Substation equipment and based on the connection point information in the equipment, the topological structure can be obtained.

[0077] In the application, pugixml can be used to parse the scd file. Traverse all Substation tags in the scd, parse the content related to ConductingEquipment in the Substation, and establish an equipment object table. Each conducting equipment contains the following information: name, type, connection point, associated IED, LN list (optional because currently there is a one-to-one relationship between switches and terminals). After generating the information table of conducting equipment, using the feeder equipment starting point as the root node, based on the connection information of the equipment, establish a tree structure data of equipment connection relationships.

[0078] Step S206, based on the tree structure data of the equipment connection relationship, set the starting position information and ending position information of the protection application topology information;

[0079] In an optional embodiment, after setting the starting position information and ending position information of the protection application topology information based on the tree structure data of the equipment connection relationship, it further includes:

[0080] When the structure of the distribution network is a ring network structure, mark the connection status of the tie switches in the distribution network ring.

[0081] In the embodiment of the present invention, set the starting position and ending position of the protection application topology information in the tree structure data of the equipment connection relationship. When the structure of the distribution network is a ring network structure, mark the connection status of the tie switches in the distribution network ring.

[0082] In a specific implementation, considering that the protection scope of the distribution substation area line protection only includes the main lines and branch lines of some lines, and then considering the multi-loop power supply situation in the distribution network, establish a file terminals.xml for describing the protection application topology. Use the topology configuration file to define startnode and endnode to represent the starting position and ending position of the application topology. If it is a ring network, mark it with del nodename according to the connection status of the tie switches in the ring network, so as to facilitate obtaining the actual network topology. The current state of the switch will be sent to the substation area protection device by means of tele-signaling, and the topology can be dynamically adjusted according to the switch state.

[0083] The config.xml is a point table file that maps IEC61850 used by the gateway to 104. The file also contains partial device parameter configurations. Therefore, after parsing this file, the 104 point table and the correspondence with 61850 logical objects can be obtained, as shown in Table 2. At the same time, the device parameters required for the program to run are obtained. The device parameters mainly include the functions of each device (communication device / outgoing line protection device / feeder terminal device), 104 server network configuration (network port number, IP address, subnet mask), master station IP, etc. The specific content is shown in the following table:

[0084]

[0085] Step S207: Generate preliminary protection application topology information according to the multi-loop power supply data of the distribution network, in combination with the starting position information and the ending position information.

[0086] In the embodiment of the present invention, preliminary protection application topology information is generated from the multi-loop power supply data of the distribution network, the starting position information, and the ending position information.

[0087] Step S208: Verify the pictures and models in the preliminary protection application topology information to obtain the protection application topology information.

[0088] In the embodiment of the present invention, the pictures and models in the preliminary protection application topology information are verified, the incorrect pictures and models are corrected to obtain the protection application topology information. After the protection application topology information is generated, when the topology structure information and / or operation mode of the distribution network changes, the protection application topology information is updated in real time.

[0089] In specific implementation, due to reasons such as communication anomalies and equipment damage in engineering applications, the ICD files received by the substation area protection device may have problems such as partial non-update or missing. It is planned to issue a picture-model inconsistency warning through a picture-model verification mechanism such as comparing with the master station topology information and perform correction configuration.

[0090] To ensure the correctness of model download and avoid misoperation of protection caused by picture-model inconsistency, the following methods are adopted: 1) To prevent personnel from making misoperations, the CIM model download process is similar to the switch control command, divided into two parts: selection - execution, and the model file must be double-confirmed before it can be downloaded into the protection device; 2) To prevent the model file from being damaged due to various accidents during transmission, each packet during transmission has a check code to ensure the correctness of the data in this packet. At the end of the transmission, the model file will also be overall verified to ensure the integrity of the model file is correct; 3) If the incorrect file is still downloaded to the protection device, further verification will be performed during terminal registration. Unauthorized devices in the model will give an alarm prompt, and the master station will also be notified of the status feedback if the authorized device is not online.

[0091] For the distribution network, the topological structure and operation mode often change, and the topology must be updated in real time. If the static topology of the network changes, such as adding a switch, the substation CIM model will be updated in real time and actively sent to the substation area protection device. At the same time, the ICD file of the newly added terminal will also be uploaded to the substation area protection device through the registration mechanism, and finally a new SCD file will be formed, and the protection application topology will be obtained by re-parsing; if the feeder topology changes dynamically, such as a switch position change, the position change information will be uploaded to the master station and the substation area protection device, and the network topology will be updated in real time.

[0092] In a method for generating a protection application topology provided by an embodiment of the present invention, by obtaining the full-station system configuration data of the distribution network and the multi-loop power supply data of the distribution network, extracting the conductive device information in the full-station system configuration data, the conductive device information is used to establish a conductive device information table, and according to the device connection relationship in the conductive device information, constructing a tree structure data of the device connection relationship, and based on the tree structure data of the device connection relationship, combining the multi-loop power supply data of the distribution network, generating protection application topology information. Through a method for generating a protection application topology, the technical problem that the existing method for generating a protection application topology is time-consuming and laborious and difficult to meet the requirements of a large-scale topology is solved, and the generation efficiency of the protection application topology is improved.
