Description

Technical Field

[0001] The present invention relates to the field of intelligent substation operation and maintenance technology, and in particular to a secondary intelligent device model selection method based on automatic identification and intelligent analysis. Background Art

[0002] The substation configuration description (SCD) of the smart substation is the core of the application and management of the smart substation. The SCD file contains all the information about the communication, type, parameters, control blocks, and inter-device connection of the intelligent electronic device (IED). As the input source of various IED devices in the smart substation, the efficiency and accuracy of its configuration directly affect the commissioning progress of the smart substation and the safe and stable operation of the power grid. At present, the SCD file is generated by the power design institute according to the planned smart substation construction scale, voltage level, wiring method and other relevant technical indicators to design the smart substation, so as to guide the design drawings and SCD configuration files for the construction and commissioning of the equipment and devices of the smart substation. The SCD configuration is generally completed independently by a designer of the design institute or an engineer of the integrator, and it is not easy to split it into multiple people to complete it independently. This results in the problem of large workload and low configuration efficiency of the SCD configuration, which is particularly prominent under time pressure. It is urgent to change the way of manually integrating SCD configuration files to automatically generating SCD files. The basis for the automatic generation of SCD files is to automatically complete the selection of secondary equipment models. Summary of the invention

[0003] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and provide a secondary intelligent device model selection method based on automatic identification and intelligent analysis. Based on a complete ICD template file library, the target ICD is automatically identified, and then the IED configuration is automatically performed, thereby laying the foundation for the automatic generation of SCD files.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] The secondary intelligent device model selection method based on automatic identification and intelligent analysis includes the following steps:

[0006] Step 1: define the file identifier of the ICD model file, create an ICD model file library for the smart substation, and determine the standard ICD model model and file identifier of the ICD model file;

[0007] Step 2: Create a smart substation engineering design information table and define the engineering design information of the smart substation engineering design information table;

[0008] Step 3: Automatically select the ICD model files in the ICD model file library based on the smart substation engineering design information table, automatically generate an IED device list based on the matching ICD model files, automatically configure the IED name and IED description, and integrate the SCD file.

[0009] The file identifier of the ICD model file in step 1 above includes:

[0010] The first type of file identification: manufacturer, model information, and version;

[0011] The second type of file identification: check code;

[0012] The third category of file identification: adapted substation type, adapted voltage level, adapted wiring method, adapted interval, adapted equipment type, adapted sampling method, and optional function information.

[0013] As mentioned above, the standard ICD model type of the ICD model file is A1-A2A3A4-A5A6-A7-A8, where A1 represents the manufacturer platform number, A2 represents the manufacturer series number, A3 represents the basic model, A4 represents the voltage level, A5 represents the substation type, A6 represents the sampling method, A7 represents the region, and A8 represents the optional model.

[0015] For the ICD model file whose model information is manufacturer platform number-(manufacturer serial number + basic model)-(substation type + sampling method)-region-version-check code,

[0016] The manufacturer platform number is assigned to A1 of the standard ICD model type in the ICD model file;

[0030] The first zone information of the model information of the ICD model file is directly assigned to parameter A1 of the standard ICD model;

[0031] When the last character of the information in zone 2 is a number 1, 2, 3, 5, 7, 0 or the character L, the last character of the information in zone 2 is assigned to parameter A4 of the standard ICD model, the second to last character of the information in zone 2 is assigned to parameter A3 of the standard ICD model, and all characters from the first character to the third to last character of the information in zone 2 are assigned to parameter A2 of the standard ICD model;

[0033] The first character of the information in the third area is assigned to parameter A5 of the standard ICD model, and the second character of the information in the third area is assigned to parameter A6 of the standard ICD model. If the information in the third area has only one character, parameter A6 is empty.

[0034] The information in zone 4 is directly assigned to parameter A7 of the standard ICD model;

[0035] The information in Area 5 is assigned bit by bit to parameter A8 of the standard ICD model.

[0054] 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 embodiments described in this application are only embodiments of a part of the present invention, rather than all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0055] The present invention proposes a secondary intelligent device model selection method based on automatic parameter recognition and intelligent analysis, such as Figure 2 As shown:

[0056] Step 1: Define the file identifier of the ICD model file, create an ICD model file library for a smart substation, and determine the standard ICD model type and file identifier of the ICD model file.

[0057] The created ICD model file library has the following characteristics:

[0058] The ICD model file library is used to store and manage ICD model files of various types of devices from various secondary equipment manufacturers. Each ICD model file in the ICD model file library should contain the manufacturer, model model information, version, check code, adapted substation type, adapted voltage level, adapted wiring method, adapted interval, adapted equipment type, adapted sampling method, and optional function information. The above information serves as the file identifier of each ICD model file.

[0059] The classification and assignment method of file identifiers of ICD model files are as follows:

[0060] The first type of file identifier: manufacturer, model information, version, is directly extracted from the ICD model file. Specifically, the type, manufacturer, and configVersion of the IED under SCL in the ICD model text are read, where type is the model information, manufacturer is the manufacturer, and configVersion is the version.

[0061] The second type of file identifier: the check code is extracted from the ICD model file name. If there is no check code in the name, the ICD model text will be subjected to full text MD5 calculation. The check code serves as the unique identifier of the ICD model file in the ICD model file library.

[0062] The third type of file identifier: adapted substation type, adapted voltage level, adapted wiring method, adapted interval, adapted equipment type, adapted sampling method, and optional function information. The specific value of the third type of file identifier is generated based on the first type of rule base and the first type of file identifier, which can be briefly summarized as defining the first type of rule base, based on the first type of file identifier covered by the first type of rule base, i.e., the manufacturer, model information, and version of the ICD model file, and realizing the information instantiation of the third type of file identifier through algorithm induction. More specific processes and implementation examples are detailed below.

[0063] The first type of rule base refers to the standard ICD model type that defines the standard ICD model file:

[0064] A1-A2A3A4-A5A6-A7-A8, A1, A2, A3, A4, A5, A6, A7, and A8 are all parameters, where A1 represents the manufacturer platform number, A2 represents the manufacturer series number, A3 represents the basic model, A4 represents the voltage level, A5 represents the substation type, A6 represents the sampling method, A7 represents the region, and A8 represents the optional model. Further through algorithm induction, all known ICD model files are matched with the standard ICD model model to form the standard ICD model model of the specific ICD model file under the standard ICD model model system.

[0065] Each specific identification object in the third category file identification can be described by the first category rule base in a rule-based manner regarding the relationship between it and the standard ICD model model parameter value of the ICD model file. Based on this relationship, any specific ICD model file, under the condition that its standard ICD model model parameter value is known, obtains the third category file identification based on the first category rule base.

[0066] Specifically, there is the following relationship between the third type of file identifier and the standard ICD model parameters:

[0067] Applicable substation type: determined by all or part of A5 and A7;

[0068] Adaptation voltage level: determined by all or part of A1, A2, A3, A4;

[0069] Adaptation wiring mode: determined by all or part of A1, A2, and A3;

[0070] Adaptation interval: determined by all or part of A1, A2, and A3;

[0071] Applicable device type: determined by all or part of A1, A2, and A3;

[0072] Adaptive sampling mode: determined by A6;

[0073] Optional function information: Determined by A8.

[0074] Preferably, in the first inductive algorithm, the model model information of the ICD model file is the standard ICD model model information, that is, the model model information is the manufacturer platform number-(manufacturer serial number+basic model)-(substation type+sampling method)-region-version-check code:

[0075] Based on statistical methods, known ICD model files are enumerated, and the model information in the ICD model file is split into key information in combination with the secondary equipment manufacturer information to form a standard ICD model model for a specific ICD model file.

[0076] For example, given the ICD model file WDLK-862A-DG-N-V1.02-C874A660.icd, the A1-A2A3A4-A5A6-A7-A8 bits of the standard ICD model of WDLK-862A-DG-N-V1.02-C874A660.icd are directly enumerated as follows:

[0077] A1:WDLK

[0078] A2: 862

[0079] A3:A

[0080] A4: Blank

[0081] A5:D

[0082] A6:G

[0083] A7:N

[0084] A8: Empty

[0085] Specifically, the first induction algorithm is based on the meaning of the specific model information of the known ICD model file, and further enumerates the standard ICD model types, so that it is directly converted into a standard ICD model system. When the meaning of the specific model information of the ICD model file is unknown, the first induction algorithm is not applicable.

[0086] Preferably, the second inductive algorithm is used for the ICD model file whose model information is non-standard ICD model information:

[0087] Based on the general induction method, combined with the model information of the actual ICD model file, several separator symbols - are identified in the model information of the ICD model file, and the standard ICD model model under the standard ICD model system of the ICD model file model is divided into different information areas. The information before the first symbol - of the model information of the actual ICD model file is the first zone information, that is, A1 corresponding to the standard ICD model model; the information between the first symbol - and the second symbol - of the model information of the actual ICD model file is the second zone information, that is, A2A3A4 corresponding to the standard ICD model model; the actual ICD model file has a standard ICD model system, and the standard ICD model system has a standard ICD model system. The information between the second symbol - and the third symbol - of the model model information of the CD model file is the information of the third zone, which corresponds to A5A6 of the standard ICD model; the information between the third symbol - and the fourth symbol - of the model model information of the actual ICD model file is the information of the fourth zone, which corresponds to A7 of the standard ICD model; the information between the fourth symbol - and the fifth symbol - of the model model information of the actual ICD model file is the information of the fifth zone, or there is only the fourth symbol - but no fifth symbol -, and the information after the fourth symbol - is the fifth information, which corresponds to A8 of the standard ICD model.

[0088] The information in zone 1 of the model information of the actual ICD model file is directly assigned to parameter A1 of the standard ICD model.

[0089] The A1 values ​​and their meanings are enumerated as follows:

[0090] A1=PCS, indicating the ICD model file of NARI relay protection PCS series;

[0091] A1=CSC, indicating the ICD model file of Beijing Sifang CSC series;

[0092] A1=CSD, indicating the ICD model file of Beijing Sifang CSD series;

[0093] A1=NSR, indicating the ICD model file of NARI NSR series;

[0094] A1=PSL, indicating the ICD model file of PSL series of GDN;

[0095] A1=SGB, indicating the ICD model file of SGB series of GDN;

[0096] A1=WBH, indicating the ICD model file of XJ Electric WBH series;

[0097] A1=WMH, indicating the ICD model file of XJ Electric WMH series;

[0098] A1=WXH, indicating the ICD model file of XJ Electric WXH series;

[0099] The above enumeration enumerates all known ICD model files according to the actual secondary equipment manufacturer's product serial number naming rules.

[0100] The method of assigning information to zone 2 is as follows:

[0101] When the last character of the information in Zone 2 is a number 1, 2, 3, 5, 7, 0 or character L, the last character of the information in Zone 2 is assigned to parameter A4 of the standard ICD model, and the second to last character of the information in Zone 2 is assigned to parameter A3 of the standard ICD model, and all characters from the first character to the third to last character of the information in Zone 2 are assigned to parameter A2 of the standard ICD model.

[0102] The A4 values ​​and their meanings are enumerated as follows:

[0103] A4=1, indicating that the ICD model file is used for 110kV voltage level;

[0104] A4=2, indicating that the ICD model file is used for 220kV voltage level;

[0105] A4=3, indicating that the ICD model file is used for 330kV voltage level;

[0106] A4=5, indicating that the ICD model file is used for 500kV voltage level;

[0107] A4=7, indicating that the ICD model file is used for 750kV voltage level;

[0108] A4=0, indicating that the ICD model file is used for 1000kV voltage level;

[0109] A4=L, indicating that the model is used for voltage levels of 110kV and below.

[0110] When the last digit is not 1, 2, 3, 5, 7, 0 or character L, the last digit of the information in zone 2 is assigned to parameter A3 of the standard ICD model, and all characters from the first digit to the second to last digit of the information in zone 2 are assigned to parameter A2 of the standard ICD model, and parameter A4 is empty.

[0111] For parameter A2, firstly, parameter A1 of the standard ICD model is distinguished, and parameter A2 and its meaning are enumerated under different matching relationships of parameter A1.

[0112] For example:

[0113] When A1=PCS, A2=931, it means that the ICD model file is used for equipment with voltage level of 220kV and above, bay type of line bay, and equipment type of protection;

[0114] When A1=PCS, A2=943, it means that the ICD model file is used for equipment with a voltage level of 110kV, a bay type of line bay, and a device type of protection.

[0115] When A1=PCS, A2=915, it means that the ICD model file is used for equipment whose bay type is bus bay and equipment type is protection.

[0116] For parameter A3, firstly, parameter A1 and parameter A2 of the standard ICD model are distinguished, and parameter A3 and its meaning are enumerated under different matching relationships between parameter A1 and parameter A2.

[0117] For example:

[0118] When A1=PCS, A2=931, A3=A, it means the ICD model file is used for the basic model, A3=C, it means the standard ICD model is used for the 2M dual-fiber series compensation line;

[0119] When A1=PCS and A2=915, A3=A indicates that the ICD model file is used for double-mother, double-mother double-split, single-mother, and single-mother segmented wiring forms; A3=C indicates that the ICD model file is used for the 3 / 2 wiring form; A3=D indicates that the corresponding ICD model file is used for double-mother single-split and single-mother three-split wiring forms.

[0120] The method of assigning information to zone 3 is as follows:

[0121] The first character of the information in zone 3 is assigned to parameter A5 of the standard ICD model, and the second character of the information in zone 3 is assigned to parameter A6 of the standard ICD model. If the information in zone 3 has only one character, parameter A6 is empty.

[0122] The A5 values ​​and their meanings are enumerated as follows:

[0123] A5=D, indicating that the model is used for GOOSE tripping;

[0124] A5 = empty, indicating that the model is used for conventional cable tripping.

[0125] Parameter A6 and its meaning are enumerated as follows:

[0126] A6=G or empty, indicating that the ICD model file is used for conventional cable sampling;

[0127] A6=A, indicating that the ICD model file is used for digital SV sampling.

[0128] The information in Zone 4 is directly assigned to parameter A7 of the standard ICD model.

[0129] The parameter A7 of the standard ICD model and its meaning are enumerated as follows:

[0130] A7=G, indicating that the model is used in the national grid area;

[0131] A7=N, indicating that the model is used in the Southern Power Grid area.

[0132] The method of assigning values ​​to the 5th zone information is as follows:

[0133] The information in area 5 is assigned bit by bit to parameter A8 of the standard ICD model, forming A8={A8 m}, that is, in order, assign the mth character of the information in zone 5 to A8m of the standard ICD model.

[0134] For A8, we first distinguish A1 and A2 of the model, and then enumerate A8 and its meaning under different matching relationships between A1 and A2.

[0135] For example:

[0136] When A1=PCS, A1=931, A81=R (when A8 has multiple optional models, A81 is used to indicate the first optional model, A82 is used to indicate the second optional model, and so on), it means that the model corresponds to the device with zero-sequence inverse time overcurrent protection, A82=P, it means that the model corresponds to the device with three-phase inconsistency protection, A83=L, it means that the model corresponds to the device with overload protection, A84=Y, it means that the model corresponds to the device with overvoltage and remote tripping protection, A85=K, it means that the model corresponds to the device suitable for 3 / 2 wiring mode, A86=D, it means that the model corresponds to the device with impact load suitable for electric railways, steel mills, etc.

[0137] The ICD model file library is formed by importing various ICD model files, specifically:

[0138] When the ICD model file is stored in the database, the information description in the ICD model file is extracted to obtain the first type of file identification and the second type of file identification, including: manufacturer, model information, version, and check code;

[0139] When the ICD model file is entered into the database, based on the enumeration relationship described in the first type of rule base, the third type of file identifier that reflects the adaptation information of the ICD model file is entered, including: adaptation substation type, adaptation voltage level, adaptation wiring method, adaptation interval, adaptation equipment type, adaptation sampling method, and optional function information.

[0140] According to the above method, the steps of storing the ICD model files described by the two types of information and assigning the file identification of the ICD model files are specifically described.

[0141] The model information of the first ICD model file WDLK-862A-DG-N-V1.02-C874A660.icd is as follows:

[0142] like Figure 2, extract the type (model information), manufacturer (manufacturer), and configVersion (version) of IED (Intelligent Electronic Device) under SCL (Structured Control Language) in the text definition of the ICD model file, type = WDLK-862A-DG-N, manufacturer = XJDQ, configVersion = V1.02, then the information description WDLK-862A-DG-N-V1.02-C874A660.icd in the ICD model file determines the manufacturer, model information, and version of the first type of file identification: the model information is WDLK-862A-DG-N, the manufacturer is XJDQ corresponding to Xuji Electric, and the version is V1.02. It should be noted that the specific example enumerated here is to facilitate professional and technical personnel working in this industry to better understand the file identification assigned to the ICD model file when the ICD model file is put into the library, and should not be used to limit the scope of application of this method.

[0143] The file CRC can be extracted from the name. That is, when the last symbol "-" in the model file name is followed by an 8-character string, it is determined to be CRC. The check code of the second-category file identifier of the model model information WDLK-862A-DG-N-V1.02-C874A660.icd of the ICD model file is C874A660.

[0144] Based on the defined standard model system and two enumeration methods, the values ​​of A1-A2A3A4-A5A6-A7-A8 corresponding to the model model information type=WDLK-862A-DG-N are A1=WDLK, A2=862, A3=A, A4=empty, A5=D, A6=G, A7=N, A8=empty. Combined with the first type of rule base and the first type of file identification, the third type of file identification of the ICD model file WDLK-862A-DG-N-V1.02-C874A660.icd is as follows: the adapted substation type is intelligent substation, the adapted voltage level is 220kV and above, the adapted wiring method is general, the adapted interval is circuit breaker, the adapted equipment type is protection, the adapted sampling method is conventional cable sampling, and the optional function information is empty.

[0145] The second model PCS-931A-DG-G-RYK.icd:

[0146] Extract the type, manufacturer, and configVersion of the IED under SCL in the text definition of the model file, type = PCS-931A-DG-G-RYK, manufacturer = NRR, configVersion = V6.02, then the first type of identification of the model PCS-931A-DG-G-RYK.icd file: the model is PCS-931A-DG-G-RYK, the manufacturer is NRR corresponding to Nanrui Relay Protection, and the version is V6.02.

[0147] Based on the defined standard model system and two enumeration methods, the values ​​of A1-A2A3A4-A5A6-A7-A8 corresponding to PCS-931A-DG-G-RYK are A1=PCS, A2=931, A3=A, A4=blank, A5=D, A6=G, A7=G, A8={R, Y, K}. Combining the first type of rule base and the first type of identification, the third type of identification of the model PCS-931A-DG-G-RYK.icd file: the adapted substation type is intelligent substation, the adapted voltage level is 220kV and above, the adapted wiring mode is 3 / 2 wiring, the adapted interval is line, the adapted equipment type is protection, the adapted sampling mode is conventional cable sampling, the optional function information is equipped with zero-sequence inverse time overcurrent protection, overvoltage and remote trip protection, and is suitable for 3 / 2 wiring mode.

[0148] Step 2: Create a smart substation engineering design information table and define various engineering design information of the smart substation engineering design information table.

[0149] The smart substation engineering design information table provides basic engineering design information, including but not limited to:

[0150] Design basic information of substation: including substation type, voltage level, and wiring method;

[0151] Design substation bay information: including bay type, bay name, bay serial number, and device configuration. The device configuration includes the number of protection sets, intelligent terminals, merging units, and acquisition execution units configured in this bay;

[0152] Design the device information within the substation bay, including manufacturer, optional functions, and sampling methods.

[0153] For example, the smart substation engineering design information table describes a 500kV smart substation in the Southern Power Grid area. The 500kV adopts 3 / 2 wiring, in which the first string is a half-string of the line, and the line interval is configured with dual line protection. The first set of protection adopts Nanrui relay protection equipment, and the second set of protection adopts Xuji electrical equipment. The first and second sets of smart terminals use Beijing Sifang equipment, and the line protection must have an overvoltage remote trip function.

[0154] Step 3: Automatically select the ICD model files in the ICD model file library based on the smart substation engineering design information table, automatically generate an IED device list based on the matching ICD model files, automatically configure the IED name and IED description, and integrate the SCD file.

[0155] Specifically:

[0156] Step 3.1, based on the bay type and device configuration in the smart substation engineering design information table, generate a list of secondary equipment for the entire station;

[0157] Step 3.2: Based on each engineering design information, assign engineering design information to each IED in the list of all station secondary devices, including: substation type, voltage level, wiring method, bay type, equipment type, bay name, set, manufacturer, optional function, and sampling method;

[0158] Step 3.3: For the engineering design information of the IED, the standard model information of the IED is formed according to the standard ICD model type rule of the ICD model file. The engineering design information of the IED includes the standard model type information.

[0159] Step 3.4, based on the standard model information of the IED, adapt the standard ICD model model of the ICD model file, and select an ICD model file matching the standard model information of the IED from the ICD model file library;

[0160] Step 3.5: Based on the voltage level, bay type, device type, bay name, and set of the IED, automatically configure the IED name and IED description, and integrate the SCD file.

[0161] Specifically, according to relevant technical specifications, the IED name is named in an 8-character format, with the 1st and 2nd digits indicating the device type, the 3rd digit indicating the bay type, the 4th and 5th digits indicating the voltage level, the 6th and 7th digits indicating the bay name, and the 8th digit indicating the set, where each bit of specific information is extracted from the engineering design information.

[0162] For example, the voltage level of an IED is 220kV, the interval type is line, the equipment type is protection, the interval name is line A, and the set is the first set. The IED name is automatically named P_L2201A, where P_ represents protection, L represents line, 22 represents 220kV, 01 represents the first group of line intervals in the 220kV line interval (during implementation, it can automatically increase from 01 onwards according to the interval name, that is, randomly select a group as 01, and the other intervals increase), and A represents the first set.

[0163] Specifically, the IED description is named according to the voltage level-bay name-set-bay type-equipment type-equipment model, wherein each set of specific information is extracted from the engineering design information.

[0164] For example, based on the engineering design information, a 500kV smart substation of China Southern Power Grid is described. The 500kV adopts 3 / 2 wiring, in which the first string is a half-string of the line, the line name is Dongfang Line, and the line interval is configured with dual line protection. The first set of protection adopts Nanrui relay protection equipment, and the second set of protection adopts Xuji electrical equipment. The first and second sets of smart terminals adopt Beijing Sifang equipment. The line protection needs to have an overvoltage remote trip function. The IED list can be formed as follows:

[0165] There are a total of 6 IEDs, including 500kV first string line protection A, 500kV first string line protection B, 500kV first string side switch intelligent terminal A, 500kV first string side switch intelligent terminal B, 500kV first string middle switch intelligent terminal A, and 500kV first string middle switch intelligent terminal B.

[0166] Furthermore, based on the engineering design information and ICD file identification enumeration information, it can be known that:

[0167] The rules of the standard ICD model model of the 500kV first string line protection A adapting ICD model file form the standard model information including: A information is the NARI relay protection platform, B information is the NARI relay protection line protection series number, C information is the basic model, C information is 500kV, D information is GOOSE tripping, E information is conventional sampling, F information is the Southern Power Grid, and G information is with overvoltage remote tripping function and suitable for 3 / 2 wiring. Further application of the first type of rule base can form specific information: A information is PCS, B information is 931, C information is A, C information is 5, D information is D, E information is G, F information is N, and G information is RK.

[0168] The same method can be used to form:

[0170] The 500kV first string switch intelligent terminal A adapts the standard ICD model type rules of the ICD model file, and the standard model information of the IED is formed including: A information is CSD, B information is 601, C information is ILB, C information is empty, D information is D, E information is G, F information is N, and G information is empty.

[0171] The 500kV first string switch intelligent terminal B adapts the standard ICD model type rules of the ICD model file, and the standard model information of the IED is formed including: A information is CSD, B information is 601, C information is ILB, C information is empty, D information is D, E information is G, F information is N, and G information is empty.

[0172] The switch intelligent terminal A in the first string of 500kV adapts the standard ICD model type rules of the ICD model file, and the standard model information of the IED is formed including: A information is CSD, B information is 601, C information is ILB, C information is empty, D information is D, E information is G, F information is N, and G information is empty.

[0173] The switch intelligent terminal B in the first string of 500kV adapts the standard ICD model type rules of the ICD model file, and the standard model information of the IED is formed including: A information is CSD, B information is 601, C information is ILB, C information is empty, D information is D, E information is G, F information is N, and G information is empty.
