[0027] The implementation of the embodiments will be described in detail below with reference to the accompanying drawings.

[0028] The embodiment provides a substation SSD file generation method. The substation SSD file generation method can be applied to various electronic devices such as a computer (PC), a tablet computer, a virtual reality / augmented reality device, a wearable device, an industrial computer, and a vehicle-mounted device. The substation SSD file generation method can also be applied to a server, a cloud, and a server cluster, and the embodiment does not specially limit this.

[0029] Figure 1 A flowchart of the substation SSD file generation method provided by the embodiment is shown.

[0030] As shown in Figure 1 , the substation SSD file generation method can include the following steps.

[0031] Step 101: Extract node information from a power system model of a substation, divide the power system according to a main device in the node information, and obtain a primary device bay.

[0032] The power system model refers to a common information model (CIM) of a power system, and the file format of the CIM is XML. The CIM includes multiple bay node information, and the bay node information represents a collection of multiple devices, and can specifically include information of devices such as a main transformer, a circuit breaker, a PT, a capacitor, and a reactor. In addition, the CIM also includes primary device topology information of the power system. The primary device topology information refers to an association relationship between primary devices.

[0033] In the embodiment, the devices in the power system are divided according to the main device in the node information, such as a transformer, a bus, a line, a capacitor, a reactor, and a circuit breaker, to obtain a primary device bay, so that the primary device bay only includes one main device. In addition to the main device, the primary device bay also needs to include other associated primary devices, and the type of the primary device bay can have certain differences under different wiring modes.

[0034] In the embodiment, the substation SSD file is formed in a hierarchical structure of a substation, a voltage level, a bay, and a conductive device. After the primary device bay is divided, a data object of the primary device bay can be generated, and the data form of the primary device bay is shown in Table 1.

[0035] Table 1: Primary device bay data

[0036]

[0037] Step 102: Obtain four-remote data of the substation, identify a common device in the power system based on the four-remote data, and determine a common device bay based on the common device.

[0038] The four-remote data refers to data monitored by an automatic monitoring system of a power system, and specifically includes telemetering data, remote signaling data, remote control data, and remote regulating data. The telemetering data refers to real-time data collected by a substation, such as voltage, current, power, and the like; the remote signaling data refers to state information of various devices in the power system, such as switch position, protection action signal, and the like, which are represented in binary form; the remote control data can include dispatch center instructions and remote operation data, such as circuit breaker opening and closing; and the remote regulating data includes adjustment of device parameters, such as transformer tap position, and the like.

[0039] Identifying the utility device in the power system based on the four-remote data specifically includes: matching the four-remote data with device monitoring specification information, and determining the utility device in the power system according to a matching result; wherein the device monitoring specification information refers to standard information of a device in the power system.

[0040] The utility device refers to a system or device in the power system that has no direct relationship with any primary device bay, such as fault recording, small current grounding line selection, low frequency and low voltage load shedding, integrated power supply system, and the like, which are analyzed and extracted through a four-remote information table.

[0041] The device monitoring specification information includes preset standard information of the device, and the utility device is identified through matching of the information and the four-remote data. Specifically: a first coverage rate of the four-remote data on the device monitoring specification information is calculated, the first coverage rate being a ratio of a number of characters matched by the four-remote data to a total number of characters of the device monitoring specification information; a second coverage rate of the four-remote data is calculated, the second coverage rate being a ratio of a number of characters matched in the four-remote data to a total number of characters of the four-remote data; and a matching result is obtained in combination of the first coverage rate and the second coverage rate.

[0042] In this embodiment, a bidirectional evaluation method is adopted, the coverage rate of the specification information on the four-remote data and the coverage rate of the four-remote data on the specification information are calculated simultaneously, and the matching result is determined comprehensively, which is beneficial to the accuracy of the matching.

[0043] Further, when the first coverage rate and the second coverage rate both exceed 0.5, a relevance reward is calculated; and a comprehensive coverage rate is obtained based on the first coverage rate, the second coverage rate, and the relevance reward. The comprehensive coverage rate can be used as the matching result.

[0044] Exemplarily, a matching score of an intersection of a two-character combination of the four-remote data and the device monitoring specification information can also be calculated; a key word matching score of the four-remote data and the device monitoring specification information is calculated; and a total score of the comprehensive coverage rate, the matching score of the intersection, and the key word matching score is calculated to obtain the matching result.

[0045] In one embodiment, a multi-dimensional scoring mechanism can be employed, combining character coverage, continuous matching, key word matching and other strategies to achieve high-precision signal matching and further realize intelligent analysis of public equipment. First, a bidirectional evaluation method is used to simultaneously calculate the coverage of the standard on the original signal and the coverage of the original signal on the standard; then a multi-dimensional score is established, combining character matching, continuous matching, key word matching and other multi-dimensional resume scoring methods; finally, the importance of different scoring dimensions is balanced through weighted average.

[0046] Specifically includes: Step I: Character-level bidirectional coverage calculation.

[0047] Standard coverage = number of matching characters in the standard / total number of characters in the standard.

[0048] Original signal coverage = number of matching characters in the original signal / total number of characters in the original signal Comprehensive coverage = transverse plate coverage * 0.6 + original signal coverage * 0.4.

[0049] Step II: Continuous matching bonus.

[0050] Extract the 2-gram (two-character combination) of the device monitoring specification information and the 2-gram of the four telemetry data, and calculate the intersection of the 2-gram of the device monitoring specification information and the four telemetry data. Using the intersection, the 2-gram matching rate of the device monitoring specification information can be calculated, i.e. the proportion of the intersection in the 2-gram of the device monitoring specification information, and similarly the 2-gram matching rate of the four telemetry data can be obtained. The matching score of the intersection = (device monitoring specification information 2-gram matching rate * 0.6 + four telemetry data 2-gram matching rate * 0.4) * 0.2.

[0051] Step III: Key word matching bonus.

[0052] Iterate through each word in the key word list and check the number of words in the four telemetry data and the device monitoring specification information. At the same time, support synonym expansion matching. Key word matching score = Σ (matching word weight) * 0.015.

[0053] Step IV: Collection requirement matching bonus. Extract the words in the collection requirement and calculate the overlap with the words in the four telemetry signal. Collection requirement bonus = min (overlap, 1.0) * 0.1.

[0054] Step V: Association bonus.

[0055] When the bidirectional coverage is greater than 0.5, an additional bonus is given. Association bonus = min (standard coverage, original signal coverage) * 0.1.

[0056] Final matching result: total score = comprehensive coverage + continuous matching bonus + key word matching bonus + collection requirement matching bonus + relevance reward.

[0057] According to the final matching result, the public equipment information is obtained, and the public equipment is extracted.

[0058] Based on the public equipment, a public equipment bay can be generated, and the public equipment bay can include two attributes of “name” and “desc”, as shown in Table 2:

[0059] Table 2: Public equipment bay data

[0060]

[0061] Step 103: For the primary equipment included in the primary equipment bay, generate primary equipment modeling information, and generate public equipment modeling information for the public equipment in the public equipment bay.

[0062] Based on the above primary equipment bay and public equipment bay, the primary equipment under the primary equipment bay level is modeled to generate primary equipment modeling information, and the public equipment under the public equipment bay is modeled to generate public equipment modeling information.

[0063] Step 104: Add a target node object to the primary equipment modeling information, the target node object is used to indicate the secondary equipment associated with the primary equipment, and generate secondary equipment modeling information for the secondary equipment.

[0064] In this embodiment, the primary equipment modeling information can refer to a primary equipment object, which includes a target node object. The information of the associated secondary equipment is saved through the target node object, thereby associating the primary equipment with the secondary equipment. The association relationship between the primary equipment and the secondary equipment can be determined through node information.

[0065] Step 105: Obtain a substation SSD file by combining the public equipment modeling information, the primary equipment modeling information, and the secondary equipment modeling information.

[0066] The substation SSD file in this embodiment is a tree structure composed of a substation, a voltage level, a bay, a transformer, and a conductive equipment. The substation, the voltage level, the bay, the transformer, and the conductive equipment are nodes in the tree structure. The above voltage level object, primary equipment modeling information, public equipment modeling information, and secondary equipment modeling information can all be nodes in the tree structure.

[0067] Based on the above steps, the embodiment further includes: generating a voltage level object according to the voltage level of the substation, determining the voltage level object corresponding to the public equipment interval; and generating the public equipment modeling information based on the voltage level object corresponding to the public equipment interval.

[0068] In the modeling process, first, the substation information is modeled. The substation has uniqueness, and it is required that one substation has only one Substation object.

[0069] The substation object contains two attributes of name and desc, and two Private elements of CIME-dtype and CIME-area, which are respectively used to describe the coding, Chinese description, substation type, and area information of the substation. The name value adopts the pinyin or abbreviation of the substation name, and the desc value adopts the dispatching naming of the substation. For example, the desc value is "Honghe 220kV Mayu Substation", and the name value is "hhmayu".

[0070] CIME-dType is a factory station type enumeration value, in which 1 represents a substation.

[0071] The CIME-area element contains two attributes of name and desc. The desc value is the grid name, the desc is the Chinese name of the grid, and the name is the grid code or English name. For example, the desc value is "Honghe", and the name value is "hh".

[0072] Then, the voltage level is modeled. One substation contains multiple voltage levels, which are sorted in descending order of voltage level.

[0073] Substation object example:

[0074] <substation name="hhmayu" desc="红河220kV玛玉变">

[0075] <private type="CIME-type" ext:dType="1" / >

[0076] <private type="CIME-area" ext:desc="红河" ext:areaname="hh" / >

[0077] ... / Substation>

[0078] The voltage level object contains two attributes, name and desc, and one Voltage object. The name attribute value should be named in the form of "xx kV" and ensure that it is unique in the whole station, such as "220 kV". The desc attribute value refers to the naming method of the name. In addition to the voltage value, the voltage level object also contains two attributes, multiplier and unit. The combination of the two attributes represents the unit of the voltage value: generally, the multiplier attribute value is "k" and the unit attribute value is "V".

[0079] According to the needs, a voltage level object with a name value of "NULL" can be created as a public equipment bay that cannot be associated with a primary equipment bay. The corresponding Voltage object value is also "NULL".

[0080] The embodiment also includes obtaining bay information from the power system model, determining the wiring mode of each voltage level according to the bay information, and supplementing the wiring mode to the corresponding voltage level object.

[0081] That is, the SSD file includes a substation object, the substation object includes different voltage level objects, and each voltage level object includes different bay objects, namely primary equipment bays and public equipment bays.

[0082] Example of voltage level object:

[0083] <voltagelevel name="220kV" desc="220kV">

[0084] <voltage unit="V" multiplier="k"> 220< / voltage>

[0085] ... / VoltageLevel>

[0086] Through the above modeling of the substation and voltage level, the construction of the basic information of a certain substation is realized, laying the foundation for the next step of interval creation.

[0087] Exemplarily, the primary equipment interval is divided and created according to the primary equipment topology information, with the principle that only one main device is contained in an interval. In addition to the main device, the primary equipment interval also includes transformer winding, tap, voltage transformer, current transformer, arrester, switch, grounding switch, arc suppression coil and other primary equipment. The primary equipment interval type mainly includes main transformer body interval, main transformer high / medium / low interval, line interval, bus interval, section interval, bus coupler interval, capacitor interval, reactor interval, station transformer interval, side switch / intermediate switch interval, etc. Table 3 shows the interval composition under common wiring modes and special case explanations (Note: the following Table 3 does not list the case containing a side bus. If the wiring mode contains a side bus, a bus and side interval is added to the interval information).

[0088] Table 3: Interval information corresponding to wiring mode

[0089]

[0090] The Bay node in the model file is matched with the full amount of conventional interval information of the station. According to the full amount of conventional interval information and Table 1, the wiring mode of each voltage level is calculated to supplement the Private element (for example, by only having one bus coupler interval to deduce the double bus wiring mode). As shown in Table 1 above, the primary equipment interval main transformer contains two attributes name and desc, and a Private element of type CIME-btype.

[0091] Example of primary equipment interval object:

[0092] <bay name="1ZB" desc="#1主变">

[0093] <private type="SF_ID32"> 2< / private>

[0094] <private type="CIME-dtype" ecim:desc="双母线" / >

[0095] …

[0096]

[0097] < / bay>

[0098] Next is the public equipment interval. The voltage level of the public equipment interval includes two cases according to the use object of the system or device function: when the system or device function is public to the whole station, such as integrated power supply system, fire fighting system, create a function interval under the voltage level of the "NULL" object; when its function is public in a certain voltage level area, such as 35kV small current grounding line selection, 35kV low frequency low voltage load reduction, then the public equipment interval should be created in the voltage level area. The common public equipment interval is shown in Table 4:

[0099] Table 4: Public equipment interval data

[0100]

[0101] Public equipment interval object example:

[0102] <bay name="XDLXX" desc="35kV小电流接地选线">

[0103] …

[0104] < / bay>

[0105] Substation primary equipment modeling: according to the equipment of each node in the model file, associated interval information is extracted, modeled, and substation primary equipment objects are generated. Substation public equipment modeling: the modeling method of public equipment and public equipment interval is the same.

[0106] Because different types of primary equipment have different meanings in the power grid, the attribute values of name and desc of each type of equipment are required to be different, and the specific cases are shown in Table 5:

[0107] Table 5: Equipment data

[0108]

[0109] The Function element is used for the connection modeling of application systems or intelligent electronic devices that cannot establish a direct association with the primary equipment interval in the substation, such as fire fighting functions, access control, etc.

[0110] The Function element can contain several SubFunction elements Function and SubFunction elements are both logical node containers Function and SubFunction elements have name and desc attributes.

[0111] Primary equipment modeling example:

[0112] <bay name="201" desc="220kV#1主变220kV侧201">

[0143] Then, all secondary equipment associated with the primary equipment are associated with the corresponding interval and primary equipment object through the logical node in which they are located.

[0144] The LNode object is used in the SSD model to describe the association between primary and secondary devices. The attributes of the LNode, iedName, ldInst, prefix, lnClass, and lnInst, form the reference of the IED logical node. Thus, the association between the primary object and the secondary device logical node can be established. Moreover, the electrical quantity of the same primary device is usually collected by multiple secondary devices such as the measurement and control device and the protection device, so a single LNode node is established for each secondary device corresponding to the single instance of the measurement under the primary device node of the SSD model.

[0145] The secondary device information is imported through the ICD file, and the description and model of the secondary device are associated and matched.

[0146] Taking the line interval as an example, the LPHD of the line protection IED and the line intelligent terminal IED is associated to the main device of the line interval; based on the SSD model, the acceptance test configuration tool automatically analyzes the logical node name, DO name, and DO description of the other secondary signals (position, tripping, reclosing, and telemetry) of the IED, and associates these signals to the corresponding primary device of the interval, and for the analog sampling relay protection device, the analog channel can also be associated to the PT and CT device. The busbar, main transformer, and other intervals are similar to the primary and secondary association of the line interval.

[0147] In the SSD model primary and secondary association design stage, the corresponding relationship between each branch of the bus protection and the primary interval cannot be determined, so after manually associating the tripping signals of each branch, the current of each branch can be automatically associated to the branch CT.
