Description

Technical Field

[0001] The present invention belongs to the technical field of secondary communication of electric power system, and more specifically, relates to communication equipment of electric power system safety automatic device and a method for generating and verifying a fixed value template file. Background Art

[0002] The power system safety automatic device is a key device to ensure the safe and stable operation of the power grid. The setting of the safety automatic device setting value is an important measure to ensure the safe and stable operation of the power grid. With the continuous development of the power system and the increasing complexity of the power grid structure, the traditional setting value setting method can no longer meet the needs of the modern power grid, so a more scientific, efficient and accurate setting value setting method is needed.

[0003] In recent years, the specification setting of setting files has become the main method for setting the setting of power system safety automatic devices. There is no need to set the setting values ​​one by one, which can speed up the setting process and reduce the setting errors caused by human operation.

[0004] As the core file of the fixed value file function, the accuracy and reliability of the fixed value template file are directly related to the safe and stable operation of the power grid. Several key technical problems in the transmission of fixed value files in the traditional mode are as follows:

[0005] 1. Problems with manual configuration of fixed value template files

[0006] In the traditional mode, the set value template files often need to be manually configured according to the set value list. This process is not only time-consuming and labor-intensive, but also highly dependent on the technical level and experience of the configuration personnel. It is easy to have configuration errors or omissions, which brings hidden dangers to the safe operation of the power grid.

[0007] 2. Problems that cannot be discovered in time after the fixed value template file is modified

[0008] Once the fixed value template file is modified, it is often difficult to detect in time.

[0009] 3. The setting file issued by the dispatching center is inconsistent with the device setting template file, which may cause device abnormality

[0010] When the set value file sent by the dispatching center station is inconsistent with the device configuration, the device uses unreasonable set values ​​after receiving and applying the set value file, which may cause the device to fail to work normally, thereby affecting the stable operation of the power grid. Summary of the invention

[0011] In view of the problems existing in the setting management of existing safety automatic devices, the present invention provides a method for generating and verifying communication equipment and setting template files for safety automatic devices, aiming to solve the problems of device abnormalities caused by manual configuration and the mismatch of setting model files when the current power system safety automatic devices receive and apply setting files of the dispatching center station, thereby improving the stability and reliability of the entire power system.

[0012] A first aspect of the present invention provides a method for generating a setting template file of a safety automatic device, comprising:

[0013] Based on the grid value list regulations, generate a resource file containing all the contents of the value list;

[0014] After the resource file is loaded into the safety automatic device, the resource file is parsed to obtain complete set value information, and a set value template file and an instantiated set value mapping file are automatically generated.

[0015] Preferably, the resource file is a full resource configuration file, including: fixed value configuration information, telemetry configuration information, telesignaling configuration information and remote control configuration information.

[0016] Preferably, through the fixed value template configuration tool, the resource file is loaded, the resource file is parsed to obtain the fixed value information, telemetry configuration information, telesignal configuration information and remote control configuration information, and the visual configuration is performed according to the fixed value file example to export the fixed value template file and the instantiated fixed value mapping file.

[0017] A second aspect of the present invention provides a verification method for a set value template file of a safety automatic device, wherein the set value template file is generated by the generation method, and the verification method comprises:

[0018] The safety automatic device parses the fixed value template file to obtain the fixed value configuration information and fixed configuration content, generates and displays the fixed value template file verification code, and is used to monitor whether the fixed value template file has changed at any time;

[0019] When the safety automatic device receives the fixed value file issued by the dispatching center station, it uses the same verification code generation method as the fixed value template file to generate the fixed value file configuration verification code of the issued fixed value file and display it;

[0020] The safety automatic device compares the check code of the fixed value file configuration with the check code of the fixed value template file to determine whether the fixed value template file is downloaded correctly.

[0021] Preferably, judging whether the fixed value template file is correctly downloaded includes:

[0022] The safety automatic device compares the check code of the setting value file configuration with the check code of the setting value template file. When the check codes are consistent, the device receives the setting value file and updates the device setting at the same time, completing the complete transmission process of the setting value file.

[0023] If the configuration check code of the fixed value file is inconsistent with the check code of the fixed value template file, the dispatch center station refuses to send the fixed value file, and sends a failure message to the dispatch center station, indicating that the reason for the failure is "the check code of the fixed value template file is inconsistent."

[0024] Preferably, if the configuration information of the setting file sent by the master station is inconsistent with the setting list, the setting file is corrected and sent to avoid the problem of setting errors of multiple devices caused by batch sending by the dispatching center station;

[0025] If the setting template file of the device is inconsistent with the setting list, correct the resource file and the function parameter module of the protection CPU to avoid functional abnormalities caused by incorrect function parameters of the device.

[0026] A third aspect of the present invention provides a safety automatic device, characterized in that the method for generating a fixed value template file is executed, the safety automatic device comprises: a communication module, a CPU function plug-in and a management plug-in;

[0027] The communication module obtains the setting list of the safety automatic device specified by the power grid and sends it to the CPU function plug-in;

[0028] The CPU function plug-in generates a resource file containing all the contents of the set value list based on the set value list of the power grid, and sends it to the management plug-in;

[0029] The management plug-in parses the resource file, obtains the complete fixed value information, and generates a fixed value template file and an instantiated fixed value mapping file.

[0030] Preferably, the safety automatic device further comprises: a fixed value template configuration tool, which is used to load resource files, perform visual configuration, and export fixed value template files and instantiated fixed value mapping files.

[0031] A fourth aspect of the present invention provides a safety automatic device, which runs the verification method of the fixed value template file, and the safety automatic device includes: a communication module, a management plug-in and a human-computer interaction interface;

[0032] The communication module is used to communicate with the dispatch center station to obtain the fixed value file;

[0033] The management plug-in is used to parse the fixed value template file and the fixed value file, generate the verification code of the fixed value template file and the fixed value file configuration verification code with the same rules, and judge whether the fixed value template file is downloaded correctly by comparison.

[0034] Preferably, the management plug-in compares the check code of the fixed value file configuration with the check code of the fixed value template file. When the check codes are consistent, the safety automatic device receives the fixed value file and updates the device fixed value at the same time, completing the complete transmission process of the fixed value file;

[0035] If the configuration check code of the fixed value file is inconsistent with the check code of the fixed value template file, the dispatch center station refuses to send the fixed value file, and sends a failure message to the dispatch center station via the communication module, marking the cause of the failure as "the check code of the fixed value template file is inconsistent" and locating the cause of the inconsistency.

[0036] Compared with the prior art, the beneficial effects of the present invention include at least:

[0037] By implementing the method of the present invention, the device abnormality caused by the mismatch of the setting value file can be effectively avoided, thereby improving the stability and reliability of the power system safety automatic device. In addition, the method can also improve the management efficiency of the setting value file and reduce the maintenance cost and time cost caused by the mismatch of the file. Therefore, the present invention has broad application prospects and promotion value in the field of setting value management of power system safety automatic devices.

[0038] Specifically, the present invention focuses more on the constant value management of safety automatic devices, and describes in more detail the generation and verification functions of the constant value template file of the device itself; 1. The constant value template file can be automatically generated to reduce the time-consuming and error-prone problems caused by manual configuration; 2. The verification code of the constant value template file can be checked in real time to determine whether the constant value template file has been changed; 3. The verification function of the constant value file sent by the master station is increased to eliminate the problem of the constant value being mistakenly changed due to the inconsistency of the fixed value template file.

[0044] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0045] The terms "first" and "second" and the like in the description and claims of the embodiments of the present application are used to distinguish different objects rather than to describe a specific order of the objects.

[0046] like Figure 1 As shown, embodiment 1 of the present invention provides a method for generating a fixed value template file of a power system safety automatic device, comprising the following steps:

[0047] Step 1: Get the setting list of the safety automatic device and send it to the safety automatic device.

[0048] It is understandable that the power grid will specify a set value list for each type of safety automatic device, including information such as set value hierarchy, set value name, set value range, set value, etc. For example, but not limited to, the following Tables 1 and 2 specify the set value content of the field component parameters of the safety automatic device.

[0049] Table 1 Busbar setting

[0050]

[0051] Table 2 Control object setting

[0052]

[0053] The safety automatic device communicates with the dispatch center master station through the protocol, and the safety automatic device setting list is sent to the safety automatic device.

[0054] Step 2: The CPU function plug-in of the safety automatic device generates a resource file containing all the contents of the setting list based on the setting list of the power grid, corresponding to the device function module.

[0055] The resource file is preferably but not limited to that shown in Table 3. In addition to the fixed value information, it also includes configuration information such as telemetry and telesignaling, and is a full resource configuration file.

[0056] Table 3 Resource file example table

[0057] Resource file value keywords meaning Example s Short URL sa="1.c9.0003" desc Setting name desc="Sudden change of line and main transformer current" LargeNo Table number LargeNo="1004" unit Fixed value unit unit="A" step Constant value step step="1" max Maximum max="9999" min Minimum min="1" setlayer Belong to the fixed value layer setlayer="1"

[0058] Step 3: After the resource file is loaded into the safety automatic device, the parsing module of the device management plug-in is responsible for parsing the resource file, obtaining complete set value information, and automatically generating a set value template file and an instantiated set value mapping file.

[0059] It is understandable that the fixed value model file is a fixed value template file shared by various manufacturers, which facilitates the dispatch center to perform batch fixed value configuration of the same type of equipment. The instantiated fixed value mapping file is a mapping relationship file between the fixed value template file and the device fixed value, which ensures the consistency of device configuration and data.

[0060] Generating a fixed value template file and an instantiated fixed value mapping file includes: according to the configuration of the current engineering application, obtaining all fixed value data based on parsing, and automatically creating a fixed value template file and an instantiated fixed value mapping file according to the fixed value file structure.

[0061] Parse and obtain all fixed value information including: classification of fixed value points and fixed configuration information such as maximum value and step size.

[0062] Automatically creating a fixed value template file from the fixed value data according to the fixed value file structure includes: based on the classification of the fixed value points and the fixed configuration information such as the maximum value and step length obtained from the above-mentioned parsed resource file, visual configuration is performed according to the fixed value file example.

[0063] Product developers can use the fixed value template configuration tool to load resource files, export fixed value template files and instantiated fixed value mapping files.

[0064] Through the above technical solution, product developers can realize the visual configuration and export of fixed value template files and instantiated fixed value mapping files by using a fixed value template file generation tool.

[0065] like Figures 2 to 4 As shown, embodiment 2 of the present invention provides a method for verifying a set value template file of a power system safety automatic device, comprising the following steps:

[0066] Step a: The management plug-in of the safety automatic device parses the fixed value template file to obtain the fixed value configuration information and fixed configuration content, generates a fixed value template file verification code, and sends it to the human-machine interface module. The fixed value template file verification code is displayed in the device interface menu to monitor whether the fixed value template file has changed at any time.

[0067] Parsing the fixed value template file to obtain the fixed value configuration information includes: screening, obtaining the fixed value configuration information such as the maximum value, minimum value, step length and range of the fixed value; parsing the fixed value template file to obtain the fixed configuration content includes: obtaining the fixed value layering, fixed value name and other fixed configuration content of the fixed value template file.

[0068] Step b: When the safety automatic device management plug-in receives the fixed value file issued by the dispatching center station, it uses the same screening and verification code generation method as the fixed value template file to generate the fixed value file configuration verification code for the issued fixed value file, and sends it to the human-machine interface module, and displays the fixed value file configuration verification code in the device interface menu.

[0069] Use CRC-32 rule to generate file checksum.

[0070] It can be understood that the fixed value file is a file obtained by instantiating the fixed value template file with fixed value numerical values. Since it is a file commonly used in the power industry, it will not be described in detail.

[0071] It is worth noting that, as one of the outstanding essential features of the present invention, the fixed value file issued by the dispatching center station is consistent with the fixed value file of the device in terms of fixed value file structure and configuration, and only the fixed value numerical part is inconsistent with the device. After issuing the fixed value file, the consistency between the fixed value file verification code displayed by the device and the fixed value file verification code displayed by the dispatching center station confirms whether the fixed value file has been issued successfully.

[0072] Step c: The safety automatic device compares the verification code of the fixed value file configuration and the verification code of the fixed value template file. Through the verification code of the fixed value template file displayed on the device human-machine interface, R&D and engineering personnel can quickly determine whether the fixed value template file is correctly downloaded.

[0073] It is understandable that, in analyzing the fixed value template file generated by the above method, in addition to the variable parts such as the fixed value value, remarks and interval name, the fixed value information such as the fixed value layer, fixed value name, maximum value, minimum value and fixed value step length in the fixed value template file need to be consistent with the fixed value list, and also need to be consistent with the fixed value file issued by the master station. Verify the consistency of the fixed value template file and the fixed value file issued by the dispatching center station, and at the same time, indirectly check whether the function module parameters of the above functional CPU plug-in are correct to ensure the correctness of the functional CPU.

[0074] The safety automatic device compares the check code of the fixed value file configuration with the check code of the fixed value template file. When the check codes are consistent, the device receives the fixed value file, updates the device setting at the same time, generates a new check code for the fixed value file, and the check code of this fixed value file is consistent with the check code of the fixed value file issued by the dispatching center station, completing the complete transmission process of the fixed value file.

[0075] If the configuration check code of the fixed value file is inconsistent with the check code of the fixed value template file, the dispatch center station refuses to send the fixed value file. At this time, a failure message is sent to the dispatch center station, indicating that the reason for the failure is "the check code of the fixed value template file is inconsistent."

[0076] In the event that the check code of the fixed value file is inconsistent with the fixed value file code obtained by the dispatching center, it is possible to quickly locate whether it is caused by the inconsistency of the fixed value template file. Specifically, the inconsistent configuration information can be quickly located by comparing the two files. If the configuration information of the fixed value file sent by the master station is inconsistent with the fixed value list, the sent fixed value file can be corrected to avoid the problem of multiple device fixed value errors caused by batch issuance by the dispatching center; if the fixed value template file of the device is inconsistent with the fixed value list, the resource file and the function parameter module of the protection CPU are corrected to avoid functional abnormalities caused by functional parameter errors in this device.

[0077] After refusing to issue the fixed value file to the dispatching center, the dispatching center can notify the manufacturer to correct the fixed value template file through the reason for refusal in the message to ensure the correctness of the fixed value template file.

[0078] There are several advantages to the above solution:

[0079] First, the engineering staff can check the verification code of the fixed value template file through the human-machine interface of the device to confirm whether the downloaded fixed value template file is correct.

[0080] Second, the dispatch center can confirm whether the device setting file is correct through the setting file verification code displayed on the device interface and the setting file verification code displayed on the dispatch center. However, when the above problem occurs, the engineering staff cannot determine which part caused it. If the verification code of the setting template file can be checked, it can quickly locate whether it is caused by the setting template file.

[0081] Embodiment 3 of the present invention provides a safety automatic device, which runs the method for generating a fixed value template file as described in Embodiment 1, and the safety automatic device includes: a communication module, a CPU function plug-in, and a management plug-in;

[0082] The communication module obtains the set value list of the safety automatic device specified by the power grid and sends it to the CPU function plug-in; the CPU function plug-in generates a resource file containing all the contents of the set value list based on the set value list regulations of the power grid, and sends it to the management plug-in; the management plug-in parses the resource file, obtains the complete set value information, and generates a set value template file and an instantiated set value mapping file.

[0083] The safety automatic device also includes: a fixed value template configuration tool for loading resource files, performing visual configuration, and exporting fixed value template files and instantiated fixed value mapping files.

[0084] Embodiment 4 of the present invention provides a safety automatic device, which runs the verification method of the fixed value template file as described in Embodiment 2, and the safety automatic device includes: a communication module, a management plug-in and a human-computer interaction interface;

[0085] The communication module is used to communicate with the dispatch center station to obtain the fixed value file; the management plug-in is used to parse the fixed value template file and the fixed value file, and generate the verification code of the fixed value template file and the fixed value file configuration verification code according to the same rules, and judge whether the fixed value template file is downloaded correctly by comparison.

[0086] The management plug-in compares the check code of the setting value file configuration with the check code of the setting value template file. When the check codes are consistent, the safety automatic device receives the setting value file and updates the device setting at the same time, completing the complete transmission process of the setting value file;

[0087] If the configuration check code of the fixed value file is inconsistent with the check code of the fixed value template file, the dispatch center station refuses to send the fixed value file, and sends a failure message to the dispatch center station via the communication module, marking the cause of the failure as "the check code of the fixed value template file is inconsistent" and locating the cause of the inconsistency.

[0088] By implementing the method and device of the present invention, it is possible to effectively avoid device abnormalities caused by mismatching of setting files, thereby improving the stability and reliability of the power system safety automatic device. In addition, the method can also improve the management efficiency of setting files and reduce the maintenance cost and time cost caused by file mismatch. Therefore, the present invention has broad application prospects and promotion value in the field of setting management of power system safety automatic devices.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
