Description

Technical Field

[0001] The present invention relates to the technical field of relay protection, and in particular to a method and system for managing setpoints of a traction substation. Background Art

[0002] With China's railway operating mileage exceeding 160,000 kilometers, including more than 46,000 kilometers of high-speed railways, China's railways have not only achieved a historic leap in coverage and transportation capacity, but also occupied a leading position in the development of global railways. This achievement is not only a victory in numbers, but also a model of coordinated progress in technology, economy and social development. The main function of the railway traction power supply system is to provide continuous and reliable power to the electric locomotives running on the railway. In order to ensure the safe and reliable power supply of the traction power supply system, relay protection plays an extremely important role. As the first line of defense of the traction power supply system, relay protection requires selectivity, speed, sensitivity and reliability when electrical accidents occur to ensure the power supply safety of the traction power supply system. The relay protection setting is the basis for determining the action of the relay protection device. The correctness of the setting directly affects the action behavior of the protection device. Traction network fault distance measurement is an important guarantee for the safe and reliable operation of the high-speed railway traction power supply system. Timely fault detection and elimination after the traction network fails can meet the safe, reliable and economical operation of the entire power supply system.

[0003] After decades of technological accumulation, my country's traction power supply system has accumulated a fault distance measurement system that integrates the methods of reactance distance measurement, up-current ratio, cross-line current ratio and up-down current ratio. The diversity and complexity of fault distance measurement algorithms are also accompanied by many problems such as a large number of fault distance measurement settings, low setting efficiency, and easy omissions and errors in manual setting inspections. Since 2019, the China Railway Group has successively promulgated the setting design specifications for relay protection of traction power supply systems, which stipulate the setting, control word and soft pressure plate of relay protection devices, and stipulate that the DL / T 61850 protocol is used for the communication of the interval protection measurement and control device. Although the relevant product setting design specifications have been promulgated, there are still problems such as protection misoperation, refusal to operate and failure to start traction network fault distance measurement due to setting errors in the commissioning and operation and maintenance of traction substation projects. The reasons come from many aspects, including unreasonable or wrong setting sheets, misunderstanding of manufacturer settings, personnel business capabilities, setting errors and inspection omissions. On the other hand, the survey found that the current means of relay protection setting management, verification, adjustment and calibration are single and inefficient, and can no longer meet the needs of the traction power supply system. Summary of the invention

[0004] The purpose of the present invention is to provide a method and system for managing set values ​​of a traction substation, which solves the problems of imperfect and unsystematic set value management at the traction substation project site, low efficiency and inability to fully back up the set value backup of the relay protection device, and inability to conveniently view the set values ​​without the relay protection device, thereby solving the problem of set value errors caused by various factors at the project site.

[0010] In a second aspect, an embodiment of the present invention provides a traction substation set value management system, comprising: a file parsing module, a set value backup module, a set value verification module and a report output module;

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1 As shown, a traction substation setting management method provided by an embodiment of the present invention is applicable to a traction substation setting management system, comprising the following steps:

[0029] Obtain the substation configuration description file of the traction substation system, parse the substation configuration description file, and obtain the communication parameters of the protection device;

[0030] Obtain the devices that require fixed value backup selected by the user, complete the fixed value backup of all traction substation devices, and generate a fixed value backup list;

[0031] Different verification rules are formulated according to different types of protection devices to perform local or online verification of fixed values ​​and obtain verification results of various fixed values;

[0032] Output the fixed value backup report according to the fixed value backup list, and output the fixed value verification report according to the fixed value verification result.

[0033] A method for managing set values ​​of a traction substation provided by an embodiment of the present invention also includes: configuring kiosk information. The system software uses the traction substation kiosk as a unit for set value management, which serves as the key information of the folder name and report for the backup of all set values. The process of configuring the kiosk information is as follows: configure the line information and traction substation information through the kiosk information module, and determine whether the configuration parameter self-check is correct. If correct, write the configuration; if incorrect, return to execute the step of determining the configuration parameter self-check. The configured information is such as XX railway XX substation, and the configured information is used to be displayed in each module of the system software and the output report. The process is as follows: Figure 2 shown.

[0034] A traction substation setting management method provided by an embodiment of the present invention also includes: parsing the SCD file of the traction substation system. In the SCD (substation configuration description) file of the traction substation system, the name field of the device ordered by the "IED" node is the device name example ZB01, the desc field is the device description example No. 1 main transformer protection device, the type field is the device model example WBH-892, and the configVersion field is the device version example V6.01. The "IED" parameter example is as follows Figure 3 As shown in the figure, the schematic diagram is a grid view; the "Communication" node contains the device station control layer network communication IP address. The system software loads the SCD file and parses the above parameters of the protection device. The process is as follows Figure 4As shown, the specific method for parsing the SCD file of the traction substation system includes the following steps:

[0035] Load the traction substation SCD file through the communication configuration module;

[0036] Resolve the iedName and its IP address under the Communication node;

[0037] Determine whether the traversal is completed;

[0038] If not, it returns to resolve the iedName and its IP address under the Communication node;

[0039] If yes, parse the configVersion parameter value and desc parameter value in the IED;

[0040] Determine whether the traversal is completed;

[0041] If not, return to execute the parsed IED parameter value of configVersion and desc;

[0042] If yes, dese, IP, and configVersion are displayed on the communication configuration module interface, and the communication configuration parameters are saved.

[0043] Furthermore, after the SCD file is parsed, the parameters of each protection device obtained by parsing are displayed on the system software communication configuration module interface. You can also select whether to perform fixed value backup for the device by checking Enable, and then click Save Settings on the software interface to save the configuration parameters. The parsed parameter format is shown in Table 1.

[0044] Table 1 System communication setting interface diagram

[0045]

[0046] The files related to the relay protection device settings are defined as three items, namely, the communication model configuration file, the data table configuration file, and the setting value table file. The three data tables are in text format, and the setting values ​​of the three configuration tables are linked by the index of the setting value. After the device is powered on, the protection program first parses the data table configuration file to generate the protection model. After the interface program runs, the communication model configuration file is matched with the protection model through keywords to generate the interface data model. The protection program then parses the setting value table file to complete the protection function.

[0047] (1) Define the device communication model configuration file format

[0048] The defined items include: device model and version, device program modification date, index of each category of constants, number of constants, name of constants, unit of constants and modeling parameters.

[0049] (2) Define the data table configuration file format

[0050] The defined items include: device model and version, device program modification date, index of each category of set values, number of set values, whether the set value is open, set value type, set value type, set value coefficient, lower and upper limits of the set value, default value of the set value and other parameters.

[0051] (3) Define the setting value table file format

[0052] The defined items include: index of each category of set value, number of set values, set value and current set value area code. The station control layer protocol of the traction substation relay protection device adopts IEC 61850, so the file transfer supports the FTP transfer protocol. The system software communicates with the protection device through the FTP protocol to obtain the communication model configuration file, data table configuration file, and set value table file, and obtain the verification code file information of a single device. The backup process of all the set values ​​of the traction substation device is as follows: Figure 5 As shown, the specific methods include:

[0053] Obtain the communication configuration information of the traction substation through the full-station set value backup module;

[0054] Create a folder based on the line station information and the backup time combination, and save it as the backup setting target folder;

[0055] Determine whether downloading the fixed value related configuration table in the order of communication configuration information is successful;

[0056] If not, continue to return to the judgment step;

[0057] If so, create a folder for the single protection device according to the device description, save the downloaded setting file in the folder, and write a backup log.

[0058] A traction substation setting management method provided by an embodiment of the present invention also includes: setting local browsing and online browsing.

[0059] Both local browsing and online browsing of fixed values ​​require obtaining the communication model configuration file, data table configuration file, and setting value table file of a single protection device. The difference between the two is that the former is based on the backed-up fixed value file, while the other is based on the network to obtain the fixed value file. The previous implementation has realized the backup of all fixed value files of the traction substation device, and all fixed value files are used as the source of local browsing of fixed values. Online browsing of fixed values ​​requires the communication network. The system software connects to a single device to obtain the fixed value file, and then parses the fixed value file and displays it on each display interface of the system software to realize online browsing of the fixed value file. Online browsing is for a single relay protection device. First, in the communication parameter setting, the communication parameters of a single device can be configured manually or by loading the SCD file to realize the communication parameter configuration of a single device. The system software setting interface is designed with a browsing fixed value area code input interface to determine the protection fixed value area code to be browsed. According to the selected local browsing or online browsing mode, the communication model configuration file, data table configuration file, and setting value table file obtained in the two modes are used to perform setting name, setting unit, setting lower limit, setting upper limit, setting value, and selected browsing setting area code on the three files, and the setting data is parsed and passed to the display module for display, such as Figure 6 shown.

[0060] A traction substation set value management method provided by an embodiment of the present invention also includes: local verification and online verification of the set values.

[0061] The local verification and online verification of fixed values ​​The way to obtain the fixed values ​​of protection devices is the same as the local browsing and online browsing methods. The verification algorithms of local verification and online verification are exactly the same. The workflow is to first formulate verification rules for different types of protection devices, such as transformer protection devices, feeder protection measurement and control devices, AT protection measurement and control devices, and fault distance measurement devices. Transformer protection devices generally include transformer main protection and transformer backup protection, so it is necessary to distinguish between main protection, backup protection and main and backup protection and set up verification rule bases separately. Fault distance measurement devices distinguish between main and sub-stations according to the installation location, and verification rules also need to be distinguished according to the installation location. Verification rule algorithms are formulated based on protection fixed values, control words, soft pressure plates, system fixed values, and manufacturer fixed value types. Set the verification results of each fixed value to generate an alarm or an error, and set the alarm item to use a yellow background in the verification result to prompt and display the alarm reason. Error items use a red background in the verification result to prompt errors and display the error reasons. Set the verification problem-free items to use the default white background without modification. Select the fixed value area code to be verified, open the fixed value file and after the parsing is completed, the display module will display it with the system interface. According to each fixed value type, the verification rule module will be loaded to locate the fixed value item by item and verify it using the set rules. According to whether the verification algorithm outputs an alarm or an error, the fixed value verification result item will be marked with a yellow or red background, and the error reason will be given. The items with no problems in the verification will use the default white background. According to the verification results of the protection fixed value, control word, soft pressure plate, system fixed value and manufacturer fixed value, calculate the number of each fixed value type, calculate the number of each fixed value alarm item, and calculate the number of each fixed value error item. Output the booth information, device model, device name, current fixed value area code, verification fixed value area code, the number of each type of fixed value, each type of fixed value alarm and error results, verification time and verification personnel to the system information interface, and use the report output module to output the fixed value verification report. The entire process is as follows. Figure 7 shown.

[0062] A method for managing set values ​​of a traction substation provided by an embodiment of the present invention also includes: writing and uploading set values.

[0063] Setting value writing and uploading can realize the setting and updating of all types of protection devices without the device, such as Figure 8 As shown, the specific process is:

[0064] Get pre-made device setting templates;

[0065] Set the self-check rules for the imported fixed value file;

[0066] According to the set value area code to be written and the set value name of the set value template, the set value is searched in the set value file according to the set value classification, the matching set value is checked, the set value type and the data format are detected to be consistent, and the current set value is written to the corresponding position of the set value file;

[0067] After all fixed values ​​are written, calculate the fixed value file check code and writing date, and write them to the end of the fixed value file;

[0068] Upload the written setting file to the protection device.

[0069] The pre-made device setting template is based on the EXCEL file to make the device setting template, and the set values ​​in the template are calculated through system parameters, etc. The name of the set value template EXCEL worksheet must not be modified after it is determined, otherwise the system software cannot read it correctly. All set values ​​in the set value template are calculated by the EXCEL template formula, and the system software does not participate in the set value calculation algorithm. Each line of the set value template must contain the set value sequence number, set value, set value description, set value type and data format, and each line represents a set value. The set value name must be the same as the set value name of the relay protection device; the set value type must be one of the four types of set value, soft pressure plate, system set value and operation set value; the set data format must be integer or floating point.

[0070] Set the self-check rules for the imported fixed value file. The fixed value type self-check rule can only be one of fixed value, soft pressure plate, system fixed value and operation fixed value. The data format self-check rule can only be integer or floating point. If the set value self-check rule is an integer data format, it cannot have a decimal point or special symbols. If it is a floating point data format, it cannot have more than 1 decimal point or special symbols. If the EXCEL fixed value template exists and the content is empty, it is defined as an illegal format. Set the fixed value modification color rule after importing the fixed value template. If the fixed value is modified after importing, the background of the set value will be changed to yellow. If the final set value is still the same as the template value, the color will be the default white.

[0071] Set the fixed value writing logic: The main steps are to select the fixed value area code to be written and the fixed value name of the fixed value template, perform customized retrieval in the fixed value file according to the fixed value classification, check the matching fixed value, detect whether the fixed value type and data format are consistent, and fully responsible for writing the current set value of the system software to the corresponding position of the fixed value file. After all the fixed values ​​are written, calculate the check code and writing time of the fixed value file, and write them to the end of the fixed value file. Output the EXCEL fixed value template file name, read the total number of fixed values, read the number of valid fixed values ​​of each type, write the fixed value area code, write the number of each type of fixed value, the reason for not writing and the corresponding fixed value name, write the result, write the fixed value file name, and write time on the display data interface. Use the fixed value upload function to select the fixed value file to be written to complete the automatic upload device.
