具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1和图2，图1是本公开实施例提供的一种智能变电站全自动闭环检测方法的流程图，而图2是本公开实施例提供的一种智能变电站全自动闭环检测方法的场景示意图。如图1所示，包括以下步骤：
步骤101、将被测变电站SCD文件与设备类型数据模板文件进行比对，以判断所述被测变电站配置信息是否正确。
需要说明地是，本公开实施例中，所述智能变电站全自动闭环检测方法应用于智能变电站全自动闭环检测装置，所述智能变电站全自动闭环检测装置包括测试平台，所述测试平台通过测试通信网络与变电站待测装置通信连接。
通过所述测试通信网络导入变电站待测装置SCD(Substation Configuration Description，变电站配置描述)文件，将导入的所述被测变电站SCD文件与预存的虚端子连线标准模板文件进行比对，进而判断所述被测变电站SCD文件配置信息是否正确。
具体地，所述步骤101还可以包括：
根据所述虚端子连线标准模板文件生成虚端子连线典型模板库；
解析所述被测变电站SCD文件，并获取所述被测变电站SCD文件中的保护及关联设备的虚端子连接关系；
将所述保护及关联设备的虚端子连接关系与所述虚端子连线典型模板库中对应的虚端子连线标准模板文件进行对比，以判断所述被测变电站SCD虚端子连接关系是否正确；
若是，读取所述被测变电站SCD文件中的模型配置信息，并获取被测变电站的装置运行模型，将所述被测变电站SCD文件中的模型配置信息与所述被测变电站的装置运行模型进行比对，以判断所述被测变电站配置信息是否正确。
本公开实施例中，首先需要对导入的所述被测变电站SCD文件的虚端子进行审查，将所述被测变电站SCD文件与所述虚端子连线标准模板文件进行 比对，检查所述被测变电站SCD文件中继电保护相关设备的虚端子配置及其连线是否正确、完整，以确保所述待测装置继电保护及关联二次设备之间的信号关联关系配置无误，进而确保后续项目测试的有效性。
具体地，基于现有标准和智能变电站典型设计方案，根据所述虚端子连线标准模板文件生成变电站继电保护相关设备的虚端子连线典型模板库，利用XML(Extensible Markup Language，可扩展标记语言)语言按照电压等级、IED(Intelligent Electronic Device，智能电子设备)类型建立虚端子连线典型模板库。获取所述被测变电站SCD文件，提取其中继电保护相关设备的虚端子连线关系，基于设备名称和设备类型，将所述被测变电站SCD文件中的待测设备与所述虚端子连线标准模板文件中相应的设备进行比对，判断该待测设备虚端子连线是否正确，并重复上述过程，直至变电站所有待测设备完成虚端子连线正确与否的比对。本实施例中，可以将所有比对结果按照连线错误、冗余和缺失等类型图形化输出，以供工作人员进行人工确认。
具体实现过程如下：
建立采用XML格式的SV输入虚端子校核模板、GOOSE输入虚端子校核模板，以节点Inputs/ExtRef下desc属性表示虚端子描述及含义，并依据每一具体的虚端子含义构建校核关键词(keywords)，校核关键词支持字符串的“与(AND)”、“或(OR)”等逻辑运算。
SV输入端子XML校核模板示例如下：
<Inputs desc＝"3/2断路器接线线路保护SV输入端子表">
<ExtRef desc＝"电压MU额定延时"keywords＝"延时|t"/>
<ExtRef desc＝"保护A相电压Ua1"keywords＝"(A相^电压^1)|Ua1"/>
<ExtRef desc＝"保护A相电压Ua2"keywords＝"(A相^电压^2)|Ua2"/>
<ExtRef desc＝"保护B相电压Ub1"keywords＝"(B相^电压^1)|Ub1"/>
<ExtRef desc＝"保护B相电压Ub2"keywords＝"(B相^电压^2)|Ub2"/>
</Inputs>
GOOSE输入端子XML校核模板示例如下：
<Inputs desc＝"3/2断路器接线线路保护GOOSE输入端子表">
<ExtRef desc＝"边断路器A相位置"keywords＝"(边断路器|边开关)^A^ 位置"/>
<ExtRef desc＝"边断路器B相位置"keywords＝"(边断路器|边开关)^B^位置/>
<ExtRef desc＝"边断路器C相位置"keywords＝"(边断路器|边开关)^C^位置/>
</Inputs>
虚端子校核模板的建立
1)建立采用XML格式的SV输出虚端子校核模板、GOOSE输出虚端子校核模板，以节点DataSet/FCDO下desc属性表示虚端子描述及含义，构建校核关键词。以GOOSE输出虚端子XML校核模板为例，如下所示：
<DataSet name＝"dsGOOSE"desc＝"3/2断路器接线线路保护GOOSE输出端子表">
<FCDO desc＝"跳边断路器A相"keywords＝"跳边断路器|跳边开关)^A"/>
<FCDO desc＝"跳边断路器B相"keywords＝"跳边断路器|跳边开关)^B"/>
<FCDO desc＝"跳边断路器C相"keywords＝"跳边断路器|跳边开关)^C"/>
</DataSet>
建立采用XML格式的SV输入软压板、GOOSE输入/输出软压板校核模板，DataSet节点下name为dsRelayEna表示为压板，以节点DataSet/FCDO下desc属性表示压板描述及含义，构建校核关键词。SV输入软压板校核模板示例如下：
<DataSet name＝"dsRelayEna"desc＝"3/2断路器接线线路保护SV输入软压板">
<FCDO desc＝"电压SV接收"keywords＝"电压^接收"/>
<FCDO desc＝"边断路器电流SV接收"keywords＝"(边断路器|边开关)^电流^接收"/>
</DataSet>
2)对SCD文件中的IED设备进行标识。导入待审SCD文件，遍历IED节点下的“name”及“desc”属性，提取IED列表，并按电压等级、IED类型(保护、合并单元、智能终端、智能组件等)、保护类型等进行分类与标识，IED 标识的目的主要是统一IED命名的规范性。
3)依据标识的IED类型，读取模板文件，搜索SCD文件中的IED/AccessPoint/Server/LDevice/LN0/Inputs/ExtRef节点，依据选择的iedName及内部短地址intAddr，按prefix/lnClass/lnInst/doName在IED/AccessPoint/Server/LDevice/LN节点下对doName描述进行匹配，如模板中有的端子而在Inputs/ExtRef下没有匹配项，则该端子属于漏配输入虚端子，如模板中没有而在Inputs/ExtRef下有的端子，则该端子属于多配输入虚端子；
4)搜索SCD文件中的IED/AccessPoint/Server/LDevice/LN0/DataSet/FCDO节点，按ldInst/prefix/lnClass/lnInst/doName/daName构成引用地址，依据构成的引用地址，列出IED/AccessPoint/Server/LDevice/LN0下的所有地址对应的虚端子描述，将该描述与模板定义的端子进行关键词匹配，如模板中有的端子而在DataSet/FCDO下没有匹配项，则该端子属于漏配输出虚端子，如模板中没有而在DataSet/FCDO下有的端子，则该端子属于多配输出虚端子。
5)按IED/AccessPoint/Server/LDevice/LN0/DataSet搜索iedName站控层访问点各逻辑节点dsRelayEna数据集，依据模板中关键词对数据集下DataSet/FCDO的压板条目进行匹配，如模板中有的压板而在DataSet/FCDO下没有匹配项，则该端子属于漏配压板，如模板中没有而在DataSet/FCDO下有的压板，则该端子属于多配压板。
6)在输入、输出虚端子校核的基础上进一步进行连线的校核。按照IED设备对IED/AccessPoint/Server/LDevice/LN0/Inputs/ExtRef节点下输入端子按iedName/ldInst/prefix/lnClass/lnInst/doName构成对侧IED输出虚端子的引用路径。根据此引用路径获取输出虚端子的描述，将输入虚端子描述与输出虚端子描述按关键词进行匹配，匹配正确的为连线正确，匹配不正确的为错配连线。
7)输出结果。对各IED给出校核结果，包括端子、压板、连线的漏配、多配、错配进行图形化标识。
当判定所述待测装置SCD虚端子连线正确，将导入的所述被测变电站SCD文件中的通信配置信息与所述虚端子连线标准模板文件中的通信模型信 息进行比对，判断所述被测变电站SCD文件配置信息是否正确，以确保变电站的待测装置与通信模型的一致性，避免测试过程中发生信号错位、通信服务异常等问题而影响测试有效性。
具体地，利用预设的XML解析器读取并解析所述虚端子连线标准模板文件，并提取其中与待测装置有关的模型配置信息，以逻辑节点为基本单位，将提取到的模型配置信息(包括逻辑节点内的数据、数据属性、数据集、各种控制块等)映射到结构体类型的MMS有名变量，按照物理设备-逻辑设备-逻辑节点-数据类型的结构树存储为模型虚端子连线标准模板文件1。
通过测试通信网络在线获取所述待测装置各层模型信息，具体为：通过Get Server Directory(读服务器目录)服务收集装置模型中所有的逻辑设备，通过Get Logical Device Directory(读逻辑设备目录)收集每个逻辑设备中的逻辑节点，通过Get Logical Node Directory(读逻辑节点目录)收集每个逻辑节点中的数据、各种控制块和数据集，通过Get Data Definition(读数据定义)读取各个数据下所有数据属性的名称和类型，通过Get Data Values(读数据值)读取各个数据的当前值，通过Get Data Set Directory(读数据集目录)获得该数据集中所有成员的名称，进而获取所述待测装置完整的分层信息模型及其当前值，并将其存储为模型虚端子连线标准模板文件2。
通过正反双向数据比对的方法，比对所述模型虚端子连线标准模板文件2是否与所述模型虚端子连线标准模板文件1一致，以判断所述被测变电站SCD文件配置信息是否正确。
步骤102、当判定所述被测变电站配置信息正确，解析所述被测变电站SCD文件并生成被测变电站SSD拓扑图。
当判定所述被测变电站SCD文件配置信息正确时，也就说明变电站的待测装置的连接关系正确，进而对所述被测变电站SCD文件进行解析，并根据解析结果生成被测变电站SSD拓扑图，从而实现变电站全站一二次设备连接信息及状态信息的可视化，方便工作人员通过所述被测变电站SSD拓扑图即能直观地获知变电站一二次设备的连接信息及状态信息，更加方便工作人员对变电站的智能管控。
具体地，所述步骤102包括：
当判定所述被测变电站配置信息正确时，解析所述被测变电站SCD文件并生成主接线图和间隔接线图以生成被测变电站SSD拓扑图，并获取被测变电站中一次设备与二次设备的关联关系；
读取所述二次设备的网络通信报文，并将所述被测变电站的运行参数映射到所述被测变电站SSD拓扑图中。
本公开实施例中，当判定所述被测变电站SCD文件配置信息正确，解析所述被测变电站SCD文件，并生成变电站一次***主接线图和间隔接线图，获取一次设备与二次逻辑设备、逻辑节点的关联关系。
进一步地，通过所述测试通信网络实时读取变电站中保护装置、合并单元、智能终端等被测二次设备的MMS、SV、GOOSE网络通信报文信息，获取被测变电站中待测装置的电流电压值、开关刀闸位置、告警信息、功能有效性信息、温度、光强等运行参数，并将上述运行参数映射到被测变电站SSD拓扑图中，实现被测变电站信息关联与状态可视化，方便设备运行维护，扩展配置文件在变电站运维检修中的应用，提升变电站安全管控水平。
步骤103、基于所述被测变电站SSD拓扑图从预设的测试项目库中获取测试项目，生成被测变电站的测试方案并进行项目测试，输出测试结果。
具体地，根据所述被测变电站SSD拓扑图，进而能够得出变电站***的拓扑结构以及各间隔保护配置，从预设的测试项目库获取测试项目，并自动生成变电站待测装置的测试方案，并根据所述测试方案对所有待测装置自动进行项目测试，通过在线读取并比对目标逻辑节点模型的状态信息，在测试过程中对测试结果进行同步自动诊断，并输出测试结果，实现变电站待测装置测试方案、测试过程及测试结果的自动闭环管理，避免了人工结果诊断带来的误差，提升了变电站闭环检测的可靠性和效率。
本公开实施例中，所述步骤103例如可以包括：
根据所述被测变电站SSD拓扑图及所述被测变电站SCD文件，获取所述被测变电站的待测装置信息；
从预设的测试项目库中提取与所述被测变电站的待测装置信息匹配的测试项目，并根据预设的排列规则将所述测试项目生成所述被测变电站的测试方案；
根据所述测试方案中的测试项目，向与所述测试项目对应的待测装置输出故障量，并对目标逻辑节点模型中与所述待测装置对应的保护逻辑节点状态信息进行置位；
将所述目标逻辑节点模型中置位后的状态信息与对应的待测装置保护逻辑节点实际运行状态信息进行比对，以对所述被测变电站进行项目测试，并输出测试结果。
具体地，有了被测变电站SSD拓扑图，结合被测变电站SCD文件，获取被测变电站共有多少套待测装置，并具体获取待测装置的型号、功能单元等信息，进而从预设的测试项目库中提取与待测装置匹配的测试项目。根据预设的排列规则，将所有待测装置的所有测试项目进行合理排列，进而生成适用于被测变电站的测试方案。
本公开实施例中，所述从预设的测试项目库中提取与所述待测装置匹配的测试项目，并根据预设的排列规则将所述测试项目生成所述被测变电站的测试方案的步骤，包括：
获取所述待测装置的保护逻辑节点，从预设的测试项目库中提取与所述保护逻辑节点匹配的测试项目；
将提取的所述测试项目按照预设的排列规则生成所述被测变电站的测试方案。
具体地，一台待测装置根据功能细化分为多个保护逻辑节点，每个保护逻辑节点具备独立的功能，不同的功能也就对应不同的测试项目。进而通过获取待测装置的保护逻辑节点，也就能从预设的测试项目库中提取与所述保护逻辑节点匹配的测试项目，将所有的测试项目按照预设的排列规则生成所述被测变电站的测试方案。
进一步地，根据所述测试项目，由故障量模块向待测装置输出故障量，并对所述目标逻辑节点模型中与所述待测装置对应的保护逻辑节点状态信息进行相应置位。智能变电站全自动闭环检测装置基于所述测试通信网络与待测装置的SV接口、GOOSE接口、MMS接口进行信息交互，通过SV、GOOSE服务实现测试闭环，通过MMS服务读取待测装置的设备逻辑节点状态信息。
将所述目标逻辑节点模型中置位后的状态信息与对应的待测装置保护逻 辑节点实际运行状态信息进行比对，待测装置并输出相应的比对结果，进而完成闭环测试。
需要说明的是，每个逻辑节点对应测试项目库中的一个测试项目，每个测试项目可以包括多个测试专项。
例如对于具有差动保护和距离保护逻辑节点的线路保护设备，根据差动保护逻辑节点PDIF，预置对应测试项目PDIF_T1，根据距离保护逻辑节点PDIS，预置对应项目PDIS_T1。测试项目中，针对逻辑节点中的定值D，预置对应测试专项PDIF_T1_D。对于一个固定的差动保护PDIF而言，差动原理是固定的，定值和控制字名称是固定的，因此对应的测试项目和测试专项也是固定的，将该测试项目PDIF_T1作为差动保护PDIF的对应测试项目进行保存，考虑PDIF差动保护原理的可扩展性，测试项目也可进行扩展，以后缀名T1、T2等进行区分。对于逻辑节点定值准确度测试，采用突加激励量的方式，在给定的误差值范围，有明确的继电器动作标准，例如对PDIF差动保护动作定值D，误差允许5％。例如，在突加激励量0.95D时，规程要求继电器不应动作，在突加激励量1.05D时，规程要求继电器应可靠动作。
通过XML解析模块对变电站被测变电站SSD拓扑图进行解析，读取待测装置逻辑节点信息，并按照逻辑节点信息从预设的测试项目库中寻找对应的测试项目，构成目标设备测试项目。在目标设备测试项目中提取待测装置模型信息，存储为目标逻辑节点模型。
测试平台故障量模块通过测试通信网络与待测装置进行SV采样数据通信，根据预置的测试项目，向待测装置输出相应的测试故障量，同时对目标逻辑节点模型中相应的设备逻辑节点进行赋值，并将得到的逻辑节点目标信息存储在目标逻辑节点模型中。具体实现过程中，通过SV服务，在T0时刻输出测试项目故障量，对目标逻辑节点模型中的相关数据进行状态赋值。例如对差动保护PDIF的测试内容为0.95D的动作定值测试，在输出0.95D故障量的同时，将目标逻辑节点模型中的PDIF.OP进行“False”赋值；测试内容为1.05D的差动保护动作定值测试，将目标逻辑节点模型中的PDIF.OP进行“True”赋值。
同时，GOOSE信息模块通过测试网络与待测装置进行GOOSE信息交互， 将GOOSE报文中保护动作时刻T1记录在GOOSE信息模块中。此外，测试平台还通过站控层接口的MMS服务获取设备动作事件报告，并将报告中的相关信息存储在设备逻辑节点状态信息中。
最后，分别读取上述目标逻辑节点模型的状态信息和设备逻辑节点状态信息中相对应的待测装置动作时刻数据，进行一致性比对，若数据一致，则表示保护动作结果正确，否则表示动作结果不正确。例如，测试平台根据保护动作时间找到T1时刻的保护动作事件报告“brcbTripInfo”，从保护动作事件报告中读取相应数据集中的“PDIF.OP”，和目标逻辑节点模型中的“PDIF.OP”进行比对，验证测试结果是否符合标准预期，生成测试结果，并将所述测试结果生成或打印标准格式的测试报告。

参见图3，图3是本公开实施例提供的另一种智能变电站全自动闭环检测方法的流程图。如图3所示，所述智能变电站全自动闭环检测方法包括：
步骤201、将被测变电站SCD文件与设备类型数据模板文件进行比对，以判断所述被测变电站配置信息是否正确。
该步骤可参照图1所示实施例中的步骤101进行实施，为避免重复，本公开实施例中对此不作赘述。
步骤202、当判定所述被测变电站配置信息正确时，解析所述被测变电站SCD文件，获取解析后的所述被测变电站SCD文件中的电压等级和间隔信息。
本公开实施例中，解析所述被测变电站SCD文件，根据解析后的所述被测变电站SCD文件分析变电站一次***拓扑连接，获取变电站的电压等级和 间隔信息。查找变电站各一次设备端子连接到的连接点，并在连接点中记下该端子。
查找线路间隔和主变各侧间隔的外部连接点，标记为母线连接点，如Mn。按照以下原则确定线路间隔和主变高/中/低压侧间隔的接线方式：有3个断路器、2个母线连接点的为3/2断路器接线间隔；有1个断路器、2个母线连接点的为双母线接线间隔；有1个断路器、1个母线连接点的为单母线接线间隔；其他为异常情况。根据母线连接点数目、线路间隔和主变各侧间隔的接线方式确定各电压等级的接线方式，对双母线接线找到其配对平行母线。
步骤203、根据所述间隔信息生成间隔拓扑特征码，并从预设的间隔设备图形模板库中获取与所述间隔拓扑特征码适配的间隔接线图模板，以生成间隔接线图。
具体地，所述间隔信息至少包括间隔内各设备类型及其拓扑连接关系，进而根据所述间隔信息生成间隔拓扑特征码。例如，从母线连接点出发遍历间隔内各设备，以单字母标识节点类型，如‘O’表示母线连接点，‘L’表示线路“IFL”,‘K’表示断路器“CBR”等等。从根节点出发遍历各节点，按先后顺序为节点编号，并以节点类型标识和编号组合成拓扑特征字符串，同一级节点放在同一级括号中，如：“O2-{G3-{D4,P5,V6},D7}”。
由间隔拓扑特征字符串生成间隔拓扑特征码，根据间隔拓扑特征码在预设的间隔设备图形模板库中查找是否存在对应的模板，如不存在则生成间隔接线图模板并存入预设的间隔设备图形模板库中，若存在则根据适配的间隔接线图模板生成对应的间隔接线图。对每个间隔执行此步骤，直至生成所有间隔的接线图。
步骤204、根据所述电压等级创建母线图元，并根据所述母线图元布局所述间隔接线图以生成主接线图。
具体地，根据所述电压等级下母线连接点信息及接线方式创建母线图元并调整母线相对位置；调取各间隔接线图，按照预设原则布局各间隔接线图并调整各电压等级图元相对位置，生成变电站一次***主接线图。
需要说明的是，所述预设原则为：(1)母线分段间隔水平位置位于两母线之间；(2)主变高/中/低压侧间隔位于母线靠近主变一侧；(3)主变设备图 元位于整个主接线图中央；高压侧位于主变之上整个主接线图的左上方；中压侧位于主变的下方；低压侧位于整个主接线图的右上方；(4)母线上的非主变间隔应根据平行母线相对位置置于所连接母线一侧。
步骤205、根据所述间隔接线图及所述主接线图生成被测变电站SSD拓扑图，并获取被测变电站中一次设备与二次设备的连接关系。
本公开实施例中，解析所述间隔接线图及所述主接线图，进而得到变电站待测装置中一次设备与二次设备的连接关系，通过测试通信网络，获取二次设备采集的开关刀闸位置、保护状态、互感器电流电压等信息，将互感器电流电压等参数信息及位置信息映射到主接线图上进行关联，将设备状态信息映射到间隔接线图上进行关联。
具体地，由断路器、刀闸(type为“CBR”和“DIS”的Conducting Equipment)下的LNode提供的信息找到关联智能终端和相应的逻辑设备、逻辑节点，若lnClass为XCBR/XSWI，则该逻辑节点下的数据对象Pos描述了此断路器或刀闸的位置信息，通过遍历此智能终端的过程层GOOSE数据集，可以定位该断路器或刀闸的位置信息是由哪个GOOSE条目所提供。
如下示例中220kV出线间隔，间隔名称为“2211”，类型为“CBR”，关联智能终端IED名称为IL2201A，ldInst为RPIT，lnClass为XCBR。依据IL2201A/RPIT/XCBR.pos查找RPIT的GOOSE数据集，查找对应的GOOSE条目映射至接线图中的断路器位置显示单元。

Figure PCTCN2018091528-appb-000002
由PT、CT(type为“VTR”和“CTR”的ConductingEquipment)下的LNode提供的信息找到关联合并单元和相应的逻辑设备、逻辑节点，若lnClass为TVTR/TCTR，则TVTR下Vol数据对象以及TCTR下的Amp数据对象分别描述了电压、电流采样值，提取并映射至接线图中的采样数据显示单元。
通过各间隔下的逻辑节点Bay/LNode查找该间隔关联保护装置和装置IED下的各逻辑节点，这些逻辑节点描述了此保护装置提供的具体保护功能，以一台线路保护为例，在Bay节点下，给出了间隔名称及描述，间隔逻辑节点下给出了PL2201A线路保护所包括的逻辑节点及实例号，如差动保护逻辑节点PDIF、距离保护逻辑节点PDIS、过流保护逻辑节点PTOC等，通过提取这些信息将间隔与间隔内的保护装置、保护功能进行关联。

步骤207、将二次设备的继电保护状态信息、元件位置信息及设备运行状态信息映射到所述被测变电站SSD拓扑图中。

根据主接线图和间隔接线图上的所有信息建立变电站一次设备与二次设备的SSD拓扑图。
步骤208、基于所述被测变电站SSD拓扑图从预设的测试项目库中获取测试项目，生成被测变电站的测试方案并进行项目测试，输出测试结果。
