Description

一种智能变电站一二次设备模型自动关联方法和装置 技术领域
本发明涉及智能变电站技术领域，具体涉及一种智能变电站一二次设备模型自动关联方法和装置。
背景技术
IEC61850标准是智能变电站建设的基础，标准定义了配置系统规范描述SSD(system specification description)文件，描述了一次系统结构及一二次设备关联关系，实际上是一个承上启下的文件，通过一二次设备关联关系，可以获取诸如某个一次设备关联哪些二次设备逻辑节点(LN，逻辑节点的缩写)、哪些二次设备逻辑节点关联同一间隔等有用信息，但以一个中等规模的220kV智能变电站为例，上百台二次设备中需与一次设备关联上千个LN，客观上这给SSD文件的应用也带来了很大的障碍，目前智能变电站集成过程中，SSD文件中基本均未关联二次设备LN，不少站甚至根本没有配置SSD文件。
近年来，智能变电站运维高级应用技术不断发展，基于二次设备信息的功能包括源于相同一次设备的模拟量及开关量同源比对分析、一二次设备状态对应监视等。由于一、二次设备关联关系不明，导致基于一二次设备状态、间隔内二次设备间状态信息的高级应用的数据基础很差，所有的配置过程都直接面对实例化的具体装置模型，单一间隔的配置工作成果完全无法复用，需要各间隔各应用功能逐一配置信号，配置效率极低，且配置正确性难于保证，一旦某个设备的模型发生变化，相关的配置工作需要重新完成。
为此，迫切要求研究如何实现智能变电站一二次设备模型自动关联，推动提升智能站基于一二次设备信息智能化高级应用功能的实用化水平。

图2是间隔关联逻辑节点工程实例化配置示意图。
具体实施方式
下面结合附图对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
实施例1：
如图1所示，一种智能变电站一二次设备模型自动关联方法，包括如下步骤：
步骤1，在ICD(IED能力描述文件)文件中，对于跨间隔二次设备模型，为模型中各间隔LN配置设定间隔前缀完成间隔LN分组，建立间隔关联LN提供一二次间隔关联接口。这样将间隔和其中的LN进行关联，通过间隔关联LN 为智能变电站集成提供间隔关联LN接口；
为ICD文件中跨间隔二次设备模型中不同间隔的功能、测量、输入输出等LN设定特定的间隔前缀；如母线保护间隔5电流幅值为B5MMXU1，间隔7跳闸为B7PTRC1等，B5和B7就是设定的间隔前缀；
间隔关联LN由各间隔名DO(数据对象)构成，例如，某个间隔关联LN结构定义如表1所示，
DO是数据对象，一个LN通常是由多个DO构成的。比如，母线保护可以保护10个间隔的母线，需要提供关联10个间隔的接口，本方法就是为此专门设置了一个间隔关联LN，这个间隔关联LN由10个间隔对应的DO构成。
表1，某个间隔关联LN结构表
Figure PCTCN2021084502-appb-000001
如表2所示，各间隔名DO的英文描述d(DO的d是这个数据对象的一个数据属性)表示该间隔特定间隔前缀名，如前所述B5、B7等，DO的value(DO的另一个数据属性)用于表示SSD文件中实际系统中的间隔名name(这个name是SSD标准定义的间隔英文名称)，用于实现与实际系统各间隔关联。
表2，母线保护间隔关联LN示例表格
DO 间隔描述 VALUE d
BAY01 母线1 EBUS4# BUS1
BAY02 母线2 EBUS5# BUS2
BAY03 母联间隔 CBR1 BC
BAY04 主变1间隔 PTR1 TR1
BAY05 主变2间隔   TR2
BAY06 主变3间隔 PTR2 TR3
BAY07 主变4间隔   TR4
BAY08 线路1间隔 LIN1 LINE1
BAY09 线路2间隔 LIN2 LINE2
BAY10 线路3间隔   LINE3
…… …… …… ……
步骤2，配置SCD文件(变电站配置描述文件)，完成各二次设备模型实例化，将配置系统规范描述SSD文件导入SCD文件，将单间隔及跨间隔二次设备的CID(IED实例配置文件)文件关联到SCD文件中SSD对应部分的相关间隔；
具体为：将各间隔配置单间隔二次设备的CID文件直接关联到SCD文件中SSD对应部分间隔；将跨间隔二次设备间隔关联LN中各间隔名DO的value赋值为SSD文件中对应实际间隔名name。
跨间隔保护ICD文件中间隔关联LN，其各间隔DO的英文描述d承载该间隔相关逻辑节点前缀名，如：BUS1、TR1等。将跨间隔二次设备模型的间隔关联LN中各间隔DO关联到SSD中的对应间隔，具体实现方法是将各间隔名DO的value赋值为SSD文件中对应实际间隔name，以完成与实际系统间隔关联。
如图2所示，图中的箭头是：将各间隔名DO的value赋值为SSD文件中对应实际间隔name的动作，间隔name是SSD文件中定义的。
母线保护间隔关联LN设置BAY1-BAY10共10个间隔DO，其中：
1、BAY01、BAY02为母线间隔，其d分别为BUS1、BUS2，表示母线间隔相关逻辑节点的前缀名分别为BUS1和BUS2，该工程的SSD中对应的母线保护间隔分别实例化为EBUS4#和EBUS5#；
