[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The same or similar reference numerals are used in the drawings to represent the same or similar modules. It should be understood that the drawings are only schematic, and the protection scope of the present application is not limited thereto.

[0020] Substations are the hub of power grids, and the safe operation of substations is a key element in the stable operation of the entire power grid. As one of the substation operation and maintenance systems, the secondary equipment relay protection information system (referred to as the protection system) works with other systems to ensure the safe operation of substations. When a power grid fails, the protection system correctly identifies the signal of the fault, collects relevant data at the time of the fault in a timely, accurate and complete manner, and provides information support for operation and maintenance personnel to find the cause of the fault and locate the fault problem, so as to eliminate the defect faster and restore power supply.

[0021] In actual substation operation, relay protection collects information through sensors such as voltage transformers and current transformers to detect the actual operating status of the equipment. When the equipment in the substation operates abnormally, the relay protection detects the faults or abnormal conditions in the power system and sends out an alarm signal. Relay protection secondary equipment refers to low-voltage electrical equipment required to monitor, control, adjust, and protect the operation of primary equipment, as well as provide operating conditions or command signals to operation and maintenance personnel. These secondary devices do not directly participate in the production and distribution of electric energy, but play a very important role in ensuring the normal operation and benefits of primary equipment. Relay protection secondary equipment includes but is not limited to relay protection devices, automatic devices, measuring meters, operating electrical appliances, and DC power supply equipment.

[0022] There are still a large number of non-"nine unified" devices in the current substation relay protection equipment. These devices are distributed in different manufacturers, different periods, and different types, resulting in differences in device model information such as non-standard naming and no total signal. It is not possible to trigger the security system to generate a power grid fault report by identifying a single fixed signal, which leads to omissions when the security system generates a power grid fault report.

[0023] Therefore, it is necessary to design a technical solution to reduce the generation of missed power grid fault reports.

[0024] Based on this, the embodiment of the present application proposes a method for managing the trigger signal of the power grid fault report of the security system. The method of the embodiment of the present application is applied to the secondary equipment relay protection information system (ie, the security system). Figure 1 The management method of the trigger signal of the power grid fault report of the trust guarantee system in the embodiment of the present application is introduced in detail. Figure 1 As shown, the method for managing the trigger signal of the power grid fault report of the trust guarantee system in the embodiment of the present application may mainly include steps S110 to S120, which are described in detail below.

[0025] It should be pointed out that the size of the serial numbers of the steps in the embodiments of the present application does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0026] In step S110, the device type of the first device is set based on the first parameter of the first device according to the type classification rule.

[0027] The first device is any one of a plurality of relay protection secondary devices, and the plurality of secondary devices correspond to a plurality of device types, and the plurality of device types correspond to a plurality of protection action signal subsets, and the plurality of protection action signal subsets constitute the protection action signal set of the security system. In other words, the plurality of device types may correspond to a plurality of different model information, and the plurality of model information corresponds to a plurality of protection action signal subsets. By quickly setting the device types of the secondary devices in batches, the basic model information of the system can be improved, which facilitates the management of the protection action signals of the same device type (or model information), and supports other applications of the security system.

[0028] Multiple relay protection secondary devices include but are not limited to relay protection devices, automatic devices, measuring meters, operating appliances and DC power supply devices. Relay protection secondary devices usually include multiple parameters such as name, description, model, type, etc. In some implementations, the first parameter may be a name and / or model. For example, the first parameter may be a name, and the first parameter may be a name and a model. The name and model are usually essential parameters for identifying secondary devices, and the name and model can be used to distinguish different protection types. In this way, the type information of the secondary device can be obtained by reading only a few parameters, which helps to quickly identify the type information of the secondary device.

[0029] The multiple equipment types include at least some or all of the following types: busbar protection, line protection, main transformer protection, backup automatic protection, capacitor protection, and reactor protection.

[0030] The type classification rules can be pre-set rules or updated and adjusted according to application requirements. In some embodiments, the type classification rule file can determine the type of the secondary device from the name and model of the secondary device through one or more rules. Each rule can have two parts: "included items" and "excluded items". The "included items" use the symbol ";" to distinguish multiple regular expressions. The "excluded items" use the symbol ";" to distinguish multiple regular expressions.

[0031] The protection action signal usually includes information such as the action behavior of each related component during the protection startup and action process, action timing, fault phase voltage and current amplitude, switch position change status, protection related constants, etc.

[0032] If the data storage structures of multiple relay protection secondary devices are different, it will be inconvenient to set and read the parameters of the secondary devices. In some implementations, the parameter information of multiple relay protection secondary devices is stored based on the same data structure. For example, multiple relay protection secondary devices can use a sequence with the same data structure, and the sequence can be a list, an array, etc. For example, it can be a list of relay protection secondary devices with the same data structure. This helps to uniformly manage the parameter information of multiple relay protection secondary devices and provide convenience for setting.

[0033] In step S120, according to the signal classification rule, the trigger attribute of the first protection action signal is set. The first protection action signal is any protection action signal in a plurality of protection action signal subsets, wherein the trigger attribute is that the triggered protection action signal is a trigger signal for generating a power grid fault report. Setting the trigger attributes of all protection action signals of the security system helps to reduce the phenomenon of omissions in the power grid fault report pushed by the security system when a substation power grid fault occurs.

[0034] Protection action signals can be divided into accident total signal and non-accident total signal. Accident total signal or action total signal, each electrical interval has an accident total signal, the accident total signal is synthesized by "OR" all protection action signals in the electrical interval. That is, when a protection action signal in an electrical interval is activated, the accident total of the electrical interval will also be activated at the same time. Non-accident total signal is an action protection signal other than the accident total signal.

[0035] The protection action signal may generally include multiple parameters such as a signal name, a signal identifier (ID), and a signal reference. In some implementations, a trigger parameter may be set, and the trigger attribute of the first protection action signal may be set by the trigger parameter. In other implementations, the signal classification rule may set the trigger attribute of the first protection action signal by setting a second parameter, wherein the second parameter may be any one of the signal name, signal identifier, and signal reference parameter. In other words, the trigger attribute of the protection action signal in the signal classification rule is set based on the second parameter. This can reduce parameter settings and help quickly obtain the trigger attribute of the protection action signal.

[0036] When reading the protection action signal, the name and identifier of the protection action signal are usually obtained. By comparing the signal name with the rules in the signal classification rule, it can be distinguished whether the protection action signal is a trigger signal generated by the power grid fault report.

[0037] The signal classification rule may be a preset rule, and the signal classification rule may also be adjusted according to application requirements. In some implementations, the signal classification rule includes a first rule set and a second rule set. Among them, the first rule set includes trigger rules for accident total signals, and the second rule set or "trigger condition" rule includes trigger rules for non-accident total signals. Setting the trigger attribute of the first protection action signal according to the signal classification rule in step S120 may include: determining whether the first protection action signal belongs to the accident total signal; if the first protection action signal belongs to the accident total signal, setting the trigger attribute of the first protection action signal based on the name of the first protection action signal according to the first rule set; if the first protection action signal does not belong to the accident total signal, setting the trigger attribute of the first protection action signal based on the name of the first protection action signal according to the second rule set. By comparing the signal name with the rules in the signal classification rule, it is distinguished whether the protection action signal is a trigger signal generated by the power grid fault report, which can reduce parameter settings and help to quickly obtain the trigger attribute of the protection action signal.

[0038] In some implementations, the signal classification rules may also include a mapping relationship table between the total accident signal and the secondary device, and the mapping relationship table may be a list of devices with the total accident signal or a set of device identifiers. Through the device name and / or device identifier, it is possible to quickly determine whether it is a total accident signal, narrow the search scope, and improve efficiency.

[0039] In some implementations, when a power grid fault report is generated, the method of the embodiment of the present application may further include: obtaining the name of the input action protection signal, as well as the device identifier and device type corresponding to the secondary device to which the action protection signal belongs, and outputting whether it is a trigger signal result. For example, according to the device identifier of the secondary device, first match the device identifier set corresponding to the "total accident signal". If it is a device in the device identifier set, match whether it satisfies any of the "total accident signal" rules (i.e., the first rule set) under the device type. If it is not a device in the set, match whether it satisfies any of the "trigger condition" rules (i.e., the second rule set) under the device type.

[0040] In the embodiment of the present application, the equipment type of all relay protection secondary devices is set according to the type classification rules, and the trigger attribute of any protection action signal is set according to the signal classification rules. In the embodiment of the present application, by setting the equipment type of secondary devices in batches, the model information of the system foundation can be improved, and the protection action signals of different model information can be managed. By setting the trigger attributes of all protection action signals, when a substation power grid fault occurs, it helps to reduce the omission of the power grid fault report generated by the security system.

[0041] The following further describes the method of the embodiments of the present application in combination with some possible implementation manners of the present application.

[0042] Figure 2 is Figure 1 A schematic flowchart of a possible implementation manner of the method. Figure 2 The method is applied to the secondary equipment relay protection information system. As Figure 2 shown, the management method of the embodiments of the present application mainly includes steps S210 to S280, and these steps will be described in detail below.

[0043] In step S210, start.

[0044] In step S220, load the list of secondary equipment.

[0045] All relay protection secondary equipment can be loaded first, and all secondary equipment has an initial type identifier. Most of these types are in an unset state, some can be incorrect device types, and some are correct device types.

[0046] In step S230, load the type classification rule file of the secondary equipment.

[0047] The type classification rule file determines the device type of the secondary equipment from the name and model of the secondary equipment through one or more rules. Each rule has a "contained item" and a "not contained item" part. The "contained item" differentiates multiple regular expressions through the symbol ";". The "not contained item" differentiates multiple regular expressions through the symbol ";".

[0048] Exemplarily, part of the encoding of the type classification rule file is as follows:

[0049] <?xml version="1.0" encoding="UTF-8"?>

[0050] <root desc="Secondary equipment type recognition script">

[0051] <ModelNameMatch desc="Device model recognition">

[0074] <ContainMatchdesc="Containment matching rule">

[0075] <Rule nameContain="Intelligent Terminal" nameNotContain=" / ">

[0076]

[0077]

[0078]

[0079]

[0080] In step S240, set the device type.

[0081] Set the device type of the first device based on the first parameter, where the first parameter can be the name and model. The name and model are used to judge and distinguish different protection types, and different types of secondary equipment for relay protection correspond to different model information.

[0082] In step S250, load the model information of the secondary equipment.

[0083] In step S260, load the classification rule file for the grid fault report trigger signal of the secondary equipment.

[0084] The signal classification rule file can be a multi-level hierarchical structure. The first level is the device type and the list of devices with the general accident signal. Multiple first-level nodes constitute this file. The next level node under the device type level is the rule level, and the rule level can include three next-level nodes: "Trigger Condition", "Non-Trigger Condition", and "General Accident Signal". Among them, the "General Accident Signal" node is the first rule set, the "Trigger Condition" node is the second rule set, and the "Non-Trigger Condition" node is the third rule set. The "Trigger Condition" and "Non-Trigger Condition" nodes can contain one or more rules. Set the trigger attribute according to the signal name (i.e., the second parameter). Each rule can have two parts: "Inclusion Items" and "Exclusion Items". Among them, the "Inclusion Items" distinguish multiple regular expressions through the symbol ";", and perform a logical "AND" operation. The "Exclusion Items" distinguish multiple regular expressions through the symbol ";", and perform an "OR" operation.

[0085] The triggering rule is exemplarily described below in conjunction with part of the program code of the signal classification rule. Part of the program code of the signal classification rule is as follows.

[0086] <? xml version='1.0'encoding='UTF-8'? >

[0087] <root>

[0088] <IedTypedesc = "n type = "1">

[0089] <TriggerRulesdesc = "Trigger condition">

[0091] <Rule UnContainName = "Alarm;Start;Return;" containName = "(Over|Low|Negative Sequence)(Voltage|Voltage Load|Current|Frequency);" / >

[0092] <Rule UnContainName = "" containName = "Three - phase inconsistency;(Action|Outlet);" / >

[0093] <Rule UnContainName = "" containName = "Three - phase tripping;" / >

[0094] <Rule UnContainName = "" containName = "Remote transmission (A|B) outlet;" / >

[0095]

[0106] <WholeMatch desc="Exact match">

[0107] <Rule matchName="Protection action" / >

[0108] <Rule matchName="Event end" / >

[0109]

[0110]

[0111]

[0112] <IedList ids="4,5,18,21,24,25,49,50,51,52" staId="1" / >

[0113] -< / root>

[0114] For example, in the included items of a rule of the "trigger condition" node, "three-phase inconsistency" and "action|export" are in a logical AND relationship, where "action" and "export" are in an OR relationship. For another example, the rules of the "accident total signal" node may include: "complete match" and "event end" rules. For example, the list of devices with accident total signals may be an identifier set, and the identifier set may be: "4,5,18,21,24,25,49,50,51,52".

[0115] In step S270, a trigger signal for reporting a secondary device power grid fault is set.

[0116] Load the protection action signal subset corresponding to all relay protection secondary devices, that is, load the entire protection action signal set. All protection action signals are initially of the "non-trigger" type. According to the signal classification rules, set the trigger attribute of any protection action signal, that is, set the trigger signal of the secondary device power grid fault report.

[0117] In step S280, end.

[0118] The overall process of setting the type of secondary equipment and the trigger attribute of the protection action signal is completed.

[0119] In the embodiment of the present application, the equipment type of all relay protection secondary devices is set according to the type classification rule, and the trigger attribute of any protection action signal is set according to the signal classification rule. In the embodiment of the present application, by setting the equipment type of secondary devices in batches, the basic model information of the system can be improved, which is convenient for managing protection action signals of different model information. By setting the trigger attributes of all protection action signals, when a substation power grid failure occurs, it helps to reduce the phenomenon of omissions in the power grid fault report generated by the security system. The type classification rules and signal classification rule files can be gradually enriched and improved to cover all secondary devices in the power grid and the protection action signal sets corresponding to the secondary devices. The method of the embodiment of the present application is universal.

[0120] Figure 3 1 is a flow chart of a method for managing a power grid fault report of a trust-guarantee system provided in an embodiment of the present application. Figure 3As shown, the management method of the power grid fault report of the information security system may mainly include steps S310 to S330, which are described in detail below.

[0121] In step S310, a protection action signal to be identified, and a device identifier and a first type corresponding to the protection action signal to be identified are obtained, where the first type is the device type to which the secondary device corresponding to the device identifier belongs.

[0122] In some embodiments, a protection action signal to be identified and a device identifier corresponding to the protection action signal to be identified are obtained. According to the mapping relationship between the secondary device and the device identifier, the secondary device corresponding to the device identifier can be determined, and then the corresponding device type can be determined, the model information corresponding to the device type can be determined, and the first protection action signal subset corresponding to the first type can be determined.

[0123] Among them, multiple relay protection secondary devices of the security system correspond to multiple device types. The device type is set according to the type classification rule and the first parameters of multiple secondary devices. The multiple device types correspond to multiple protection action signal subsets, and the multiple protection action signal subsets constitute the protection action signal set of the security system.

[0124] The multiple relay protection secondary devices include but are not limited to relay protection devices, automatic devices, measuring meters, operating appliances and DC power supply devices. The multiple equipment types include at least some or all of the following: busbar protection, line protection, main transformer protection, backup automatic protection, capacitor protection, reactor protection. The first type can be any type of the multiple equipment types.

[0125] In step S320, it is determined whether the trigger attribute of the protection action signal to be identified matches the trigger rule corresponding to the first type in the signal classification rule.

[0126] Since the first type corresponds to the first protection action signal subset, in other words, it is determined whether the trigger attribute of the protection action signal to be identified matches the trigger rule corresponding to the first protection action signal subset in the signal classification rule.

[0127] In step S330, in response to the trigger attribute matching the trigger rule corresponding to the first type, the protection action signal to be identified is determined to be a trigger signal, and a power grid fault report corresponding to the protection action signal to be identified is generated.

[0128] In the embodiment of the present application, by setting the device types of secondary devices in batches, the model information of the system foundation can be improved, and the protection action signals of different model information can be managed. By setting the trigger attributes of all protection action signals, when a substation power grid fault occurs, the trigger attributes of the protection action signal can be identified, so that a power grid fault report can be generated according to the trigger signal, which helps to reduce the omission of the power grid fault report generated by the security system.

[0129] Combination of the above Figure 1-Figure 3 The method embodiment of the present application is described in detail. Figures 4 to 6 The device embodiment of the present application is described in detail. It should be understood that the description of the device embodiment corresponds to the description of the method embodiment, so the parts not described in detail can refer to the previous method embodiment.

Figure 4 As shown, the management device 400 for triggering signal of power grid fault report of the information security system includes: a first setting module 410 and a second setting module 420.

[0131] The first setting module 410 or the type setting module is used to set the device type of the first device based on the first parameter of the first device according to the type classification rule. The first device is any one of a plurality of relay protection secondary devices, the plurality of secondary devices correspond to a plurality of device types, the plurality of device types correspond to a plurality of protection action signal subsets, and the plurality of protection action signal subsets constitute a protection action signal set of the security system.
