Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

实施例1Example 1

如图1所示，一种自动审查SCD文件虚端子跨间隔误连接方法，从导入SCD文件到完成GOOSE虚端子跨间隔误连接的自动审查包括以下步骤：As shown in Figure 1, a method for automatically reviewing the misconnection of virtual terminals across intervals in SCD files, from importing the SCD file to completing the automatic review of misconnections of GOOSE virtual terminals across intervals includes the following steps:

步骤1、解析SCD文件，遍历IED列表，获取设备名称，并按照设备名称对设备进行分类；Step 1, parse the SCD file, traverse the IED list, obtain the device name, and classify the device according to the device name;

本实施例中设备名称从IED列表中每个IED下的IED name(设备名称)节点获取，根据获取的IED name中设备类型属性将设备分为保护(P)、合并单元(M)、智能终端(I)、测控(C/S)。In this embodiment, the device name is obtained from the IED name (device name) node under each IED in the IED list, and the device is divided into protection (P), merging unit (M), and intelligent terminal according to the device type attribute in the obtained IED name. (I), measurement and control (C/S).

所述IED name的命名规则为设备类型+间隔类型+电压等级+支路编号+A/B套，其中，设备类型包括：保护P、测控C/S、合并单元M、智能终端I，间隔类型包括：线路L、母线M、母联/分段E、主变T，电压等级包括：750kV、500kV、220kV、110kV、35kV、10kV。The naming rule of the IED name is equipment type + interval type + voltage level + branch number + A/B set, wherein the equipment type includes: protection P, measurement and control C/S, merging unit M, intelligent terminal I, interval type Including: line L, bus M, bus coupler/section E, main transformer T, voltage levels include: 750kV, 500kV, 220kV, 110kV, 35kV, 10kV.

步骤2、提取分类后设备的设备信息；设备信息分为三层：Step 2. Extract the device information of the classified device; the device information is divided into three layers:

第一层为IED信息，包括设备类型、设备名称，依据SCD文件中该设备的IED name关键字进行匹配；The first layer is IED information, including device type and device name, which is matched according to the IED name keyword of the device in the SCD file;

第二层为链路信息，包括SV链路信息和GOOSE链路信息，为该设备所有发布/订阅的SV链路信息和GOOSE链路信息；The second layer is link information, including SV link information and GOOSE link information, which is the SV link information and GOOSE link information published/subscribed by the device;

第三层为外部IED信息，与该设备有GOOSE链路连接的其他设备的信息，包括设备类型、设备名称，依据SCD文件中IED name关键字匹配。The third layer is the external IED information, the information of other devices connected to the device with GOOSE links, including device type and device name, which are matched according to the IED name keyword in the SCD file.

对于GOOSE链路，提取IED中G1访问点下逻辑设备实例节点LDeviceinst(PI或者PIGO)中各逻辑设备的逻辑节点类LN0 lnClass(LLN0)下数据集信息节点(以下简称dataSet)的FCDA(功能约束数据属性)和Inputs(外部信号引用)节点信息为GOOSE链路信息。dataSet中FCDA包括如下元素，ldInst(逻辑设备实例)、prefix(前缀)、lnClass(逻辑节点类)、lnInst(逻辑节点实例)、doName(数据对象名称)、daName(数据属性)；FCDA下所有元素信息组合为本IED发布的GOOSE链路信息。For the GOOSE link, extract the FCDA (functional constraint) of the data set information node (hereinafter referred to as dataSet) under the logical node class LN0 lnClass (LLN0) of each logical device in the logical device instance node LDeviceinst (PI or PIGO) under the G1 access point in the IED Data attribute) and Inputs (external signal reference) node information is GOOSE link information. FCDA in dataSet includes the following elements, ldInst (logical device instance), prefix (prefix), lnClass (logical node class), lnInst (logical node instance), doName (data object name), daName (data attribute); all elements under FCDA The information combination is the GOOSE link information released by this IED.

Inputs中ExtRef(外部属性引用)包括如下元素，iedName(设备名称)、prefix、lnClass、lnInst、doName、daName、intAddr(内部地址)；ExtRef下所有元素信息组合为本IED订阅的GOOSE链路信息。ExtRef (external attribute reference) in Inputs includes the following elements, iedName (device name), prefix, lnClass, lnInst, doName, daName, intAddr (internal address); all element information under ExtRef is combined into the GOOSE link information subscribed by this IED.

同理，对于SV链路信息，IED模型中M1访问点下FCDA下ldInst、prefix、lnClass、lnInst、doName、daName、fc元素信息组合为本IED发布的SV链路信息；ExtRef下iedName、prefix、lnClass、lnInst、doName、daName、intAddr元素信息组合为本IED订阅的SV链路信息。Similarly, for SV link information, the combination of ldInst, prefix, lnClass, lnInst, doName, daName, and fc element information under FCDA under M1 access point in the IED model is the SV link information released by this IED; iedName, prefix, The combination of lnClass, lnInst, doName, daName, and intAddr element information is the SV link information subscribed by this IED.

步骤3、根据设备信息对全站设备进行间隔划分；如图2所示，为典型间隔示意图，在本实施例中，以线路间隔为例，间隔划分原则如下：Step 3. Carry out interval division for all station equipment according to the equipment information; as shown in Figure 2, it is a typical interval schematic diagram. In this embodiment, taking the line interval as an example, the interval division principle is as follows:

搜索与线路保护有SV/GOOSE订阅/发布关系的其他直接关联IED，图2中可知，线路合并单元与线路保护之间有SV订阅/发布；线路智能终端与线路保护之间有GOOSE订阅/发布；线路测控与线路保护之间有GOOSE订阅/发布；母线保护与线路保护之间有GOOSE订阅/发布；比对与线路保护直接关联IED的IED name，其中线路合并单元、线路智能终端和线路测控与线路保护的间隔类型、电压等级、支路编号均一致，而母线保护与线路保护的间隔类型不一致，所以线路保护、线路合并单元、线路智能终端以及线路测控为一个线路间隔。Search for other directly related IEDs that have a SV/GOOSE subscription/publishing relationship with the line protection, as shown in Figure 2, there is an SV subscription/publishing between the line merging unit and the line protection; there is a GOOSE subscription/publishing between the line intelligent terminal and the line protection ; There is GOOSE subscription/publishing between line monitoring and control and line protection; there is GOOSE subscription/publishing between busbar protection and line protection; compare the IED name of the IED directly associated with line protection, among which the line merging unit, line intelligent terminal and line monitoring and control The bay type, voltage level, and branch number are consistent with the line protection, but the busbar protection is inconsistent with the line protection bay type, so the line protection, line merging unit, line intelligent terminal, and line monitoring and control are one line bay.

步骤4、遍历所有IED，获取每个IED中所有GOOSE虚端子的输入端子地址和输出端子地址；Step 4. Traverse all IEDs to obtain the input terminal addresses and output terminal addresses of all GOOSE virtual terminals in each IED;

GOOSE虚端子的输入端子地址和输出端子地址获取方式为，将IED name与IED中G1访问点下inputs节点中intaddr信息组合，存储为输出端子地址；将Inputs节点下ExtRef元素信息中prefix、ldInst、lnClass、lnInst、doName、daName组合为外部地址，并与ExtRef元素信息中iedName一起存储为输入端子地址，输出端子地址与输入端子地址共同组成一条完整的GOOSE虚端子。The way to obtain the input terminal address and output terminal address of GOOSE virtual terminal is to combine the IED name with the intaddr information in the inputs node under the G1 access point in the IED, and store it as the output terminal address; the prefix, ldInst, lnClass, lnInst, doName, and daName are combined into an external address, and stored together with iedName in the ExtRef element information as an input terminal address, and an output terminal address and an input terminal address together form a complete GOOSE virtual terminal.

步骤5、每一个GOOSE虚端子分别与除自身外的其他GOOSE虚端子比对输入端子地址和输出端子地址，根据比对结果，分类存储参与比对的GOOSE虚端子为正确GOOSE虚端子、异常GOOSE虚端子或待检GOOSE虚端子；如图3所示，为GOOSE虚端子比对过程示意图，图中Addr IN表示输入端子地址，AddrOUT表示输出端子地址，GOOSE虚端子比对原则为：Step 5. Each GOOSE virtual terminal compares the input terminal address and output terminal address with other GOOSE virtual terminals except itself, and according to the comparison results, classify and store the GOOSE virtual terminals participating in the comparison as correct GOOSE virtual terminals and abnormal GOOSE Virtual terminal or GOOSE virtual terminal to be checked; as shown in Figure 3, it is a schematic diagram of the comparison process of GOOSE virtual terminals. In the figure, Addr IN indicates the input terminal address, and AddrOUT indicates the output terminal address. The principle of GOOSE virtual terminal comparison is:

每一个GOOSE虚端子作为源GOOSE虚端子分别与除自身外的其他GOOSE虚端子比对输入端子地址和输出端子地址；Each GOOSE virtual terminal is used as the source GOOSE virtual terminal to compare the input terminal address and output terminal address with other GOOSE virtual terminals except itself;

当源GOOSE虚端子的输出端子地址、输入端子地址均不与所有参与比对的GOOSE虚端子一致时，存储源GOOSE虚端子为正确GOOSE虚端子；When the output terminal address and input terminal address of the source GOOSE virtual terminal are not consistent with all the GOOSE virtual terminals participating in the comparison, the stored source GOOSE virtual terminal is the correct GOOSE virtual terminal;

当源GOOSE虚端子的输入端子地址与参与比对的GOOSE虚端子的输入端子地址一致，而输出端子地址不一致时，存储源GOOSE虚端子和参与比对的GOOSE虚端子为异常GOOSE虚端子；When the input terminal address of the source GOOSE virtual terminal is consistent with the input terminal address of the GOOSE virtual terminal participating in the comparison, but the output terminal address is inconsistent, the storage source GOOSE virtual terminal and the GOOSE virtual terminal participating in the comparison are abnormal GOOSE virtual terminals;

当源GOOSE虚端子的输出端子地址与参与比对的GOOSE虚端子的输出端子地址一致，而输入端子地址不一致时，存储源GOOSE虚端子和参与比对的GOOSE虚端子为待检GOOSE虚端子。When the output terminal address of the source GOOSE virtual terminal is consistent with the output terminal address of the GOOSE virtual terminal participating in the comparison, but the input terminal address is inconsistent, the storage source GOOSE virtual terminal and the GOOSE virtual terminal participating in the comparison are the GOOSE virtual terminals to be checked.

步骤5所述正确GOOSE虚端子为正确链路，不需要跨间隔审查；异常GOOSE虚端子为错误链路，直接报告链路错误；待检GOOSE虚端子需进行跨间隔审查。所以以下通过步骤6的方法对待检GOOSE虚端子进行跨间隔审查。The correct GOOSE virtual terminal mentioned in step 5 is a correct link and does not need to be checked across intervals; the abnormal GOOSE virtual terminal is an incorrect link, and the link error is directly reported; the GOOSE virtual terminal to be checked needs to be checked across intervals. Therefore, the method of step 6 is used to conduct cross-interval inspection of the GOOSE virtual terminal to be inspected.

步骤6、将待检GOOSE虚端子，按照输出端子地址中的IED name进行分组，取出分组后的每个GOOSE虚端子的输入端子地址的IED name，根据输入端子地址的IED name匹配步骤3中已划分的间隔；根据同组IED的所属间隔评估是否存在GOOSE虚端子跨间隔误连接。具体审查过程为：Step 6. Group the GOOSE virtual terminals to be checked according to the IED name in the output terminal address, take out the IED name of the input terminal address of each GOOSE virtual terminal after grouping, and match the IED name in step 3 according to the IED name of the input terminal address Divided intervals; evaluate whether there is a false connection of GOOSE virtual terminals across intervals according to the intervals to which IEDs of the same group belong. The specific review process is:

本组IED均属于同一间隔，则本组GOOSE端子为正确的GOOSE虚端子；All IEDs in this group belong to the same interval, so the GOOSE terminal in this group is the correct GOOSE virtual terminal;

本组IED属于2个不同间隔，且2个不同间隔属于同一电压等级，其中一个间隔为母线间隔，则本组GOOSE虚端子为正确的GOOSE虚端子；This group of IEDs belongs to 2 different bays, and the 2 different bays belong to the same voltage level, and one of the bays is a bus bay, then the GOOSE virtual terminal in this group is the correct GOOSE virtual terminal;

本组IED属于2个间隔，且2个间隔分属不同电压等级，则本组GOOSE虚端子属于跨间隔误连接；This group of IEDs belongs to 2 bays, and the 2 bays belong to different voltage levels, then this group of GOOSE virtual terminals belongs to misconnection across bays;

本组IED属于2个间隔，2个间隔属于同一电压等级，但2个间隔中没有母线间隔，则本组GOOSE虚端子属于跨间隔误连接；The IEDs in this group belong to 2 bays, and the 2 bays belong to the same voltage level, but there is no bus bar bay in the 2 bays, then the GOOSE virtual terminals in this group belong to misconnection across bays;

本组IED属于超过2个间隔，则本组GOOSE虚端子属于跨间隔误连接。If the IEDs in this group belong to more than 2 bays, then the GOOSE virtual terminals in this group belong to misconnections across bays.

通过以上技术方案，本发明通过遍历SCD文件IED列表，读取IED的设备信息，按照设备信息对IED进行间隔划分；取每个IED中所有GOOSE虚端子的输入端子地址和输出端子地址，比对各个IED的GOOSE虚端子，从而实现GOOSE虚端子跨间隔误连接的自动审查。Through the above technical scheme, the present invention reads the device information of the IED by traversing the IED list of the SCD file, and divides the IED according to the device information; takes the input terminal addresses and output terminal addresses of all GOOSE virtual terminals in each IED, and compares them GOOSE virtual terminals of each IED, so as to realize the automatic review of wrong connection of GOOSE virtual terminals across intervals.
