本发明涉及电力技术领域，尤其涉及一种基于SVG的在线监测数据自动集成监控方法。The invention relates to the field of electric power technology, in particular to an SVG-based automatic integrated monitoring method for online monitoring data.
背景技术Background technique
作为电力系统图形交换的标准，基于XML（Extensible Markup Language，可扩展标记语言）的可伸缩矢量图SVG（Scalable Vector Graphics）在电力系统中得到了广泛的应用。电网公司通过SCADA（Supervisory Control And Data Acquisition，数据采集与监视控制系统）实时数据和SVG一次接线图的结合应用实现了对电网运行的实时监控。As a standard for power system graphics exchange, scalable vector graphics SVG (Scalable Vector Graphics) based on XML (Extensible Markup Language) has been widely used in power systems. The power grid company realizes real-time monitoring of power grid operation through the combined application of SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control system) real-time data and SVG primary wiring diagram.
随着在线监测技术的成熟，电力设备的在线监测应用也越来越广泛，如GIS（GAS INSULATED SWITCHGEAR，气体绝缘全封闭组合电器）局放在线监测和变压器油色谱在线监测基本成为220kV及以上变电站的标准配置。在线监测系统为电力设备管理业务提供了良好的数据来源，基于在线监测数据的电力设备运行实时监控也已成为电网公司精细化管理的迫切需求。With the maturity of online monitoring technology, the application of online monitoring of power equipment is becoming more and more extensive. For example, GIS (GAS INSULATED SWITCHGEAR, gas insulated fully enclosed combined electrical appliances) local on-line monitoring and transformer oil chromatography on-line monitoring have basically become 220kV and above substations. standard configuration. The online monitoring system provides a good data source for the power equipment management business, and the real-time monitoring of the power equipment operation based on the online monitoring data has become an urgent need for the refined management of the power grid company.
为了实现对电网运行状态和电力设备运行状态的实时监控，需要结合SCADA实时数据、在线监测数据和SVG一次接线图进行集成应用。目前电网公司绘制好的SVG一次接线图只涵盖一次设备及其连接关系，未包含二次设备信息及其与一次设备的关系；SVG一次接线图也只与SCADA数据模型实现了绑定，未绑定在线监测数据模型。In order to realize the real-time monitoring of the operating status of the power grid and power equipment, it is necessary to combine SCADA real-time data, online monitoring data and SVG primary wiring diagram for integrated application. At present, the SVG primary wiring diagram drawn by the power grid company only covers the primary equipment and its connection relationship, and does not include the secondary equipment information and its relationship with the primary equipment; the SVG primary wiring diagram is only bound to the SCADA data model. Define the online monitoring data model.
现有技术通常是由人工通过SVG编辑器实现SVG一次接线图的修改，整个过程包括定义二次设备图元、在一次接线图基础上绘制二次设备图元、以及绑定在线监测数据模型。此方法对于拥有几百个变电站的电网来说工作量很大，实用性及便利性较差。In the prior art, the SVG primary wiring diagram is usually modified manually through an SVG editor. The whole process includes defining the secondary equipment graphic elements, drawing the secondary equipment graphic elements on the basis of the primary wiring diagram, and binding the online monitoring data model. This method has a lot of work for a power grid with hundreds of substations, and its practicability and convenience are poor.

具体实施方式Detailed ways
参见图1，本发明提供的一种基于SVG的在线监测数据自动集成监控方法，包括：Referring to Fig. 1, a kind of SVG-based online monitoring data automatic integrated monitoring method provided by the present invention comprises:
步骤101，采用可伸缩矢量图SVG通用格式定义二次设备图元；Step 101, adopting the universal format of scalable vector graphics SVG to define the graphic elements of the secondary equipment;
具体的，采用SVG通用格式定义各类常用二次设备图元，如油色谱在线监测装置、局部放电在线监测装置等。Specifically, the SVG general format is used to define various commonly used secondary equipment graphic elements, such as oil chromatography on-line monitoring devices, partial discharge on-line monitoring devices, etc.
需要说明的是：二次设备图元是生成二次设备图形的基础。比如一般先定义一个小矩形框作为油色谱在线监测装置图元，然后在接线图中所有油色谱在线监测装置都以矩形框展示，其中某个矩形框即为对应油色谱在线监测装置的图形。It should be noted that: the secondary equipment graphic element is the basis for generating secondary equipment graphics. For example, a small rectangular box is generally defined as the graphic element of the online oil chromatography monitoring device, and then all the online oil chromatography monitoring devices are displayed in rectangular boxes in the wiring diagram, and one of the rectangular boxes is the graphic of the corresponding oil chromatography online monitoring device.
SVG通用格式如下：The general format of SVG is as follows:
<symbol id="图元名" class=”样式表名”><symbol id="element name" class="style sheet name">
</symbol></symbol>
其中，id属性定义图元的标识，表示某一类二次设备，在<symbol>组中可以详细定义各类二次设备图元的形状。Among them, the id attribute defines the identity of the graphic element, indicating a certain type of secondary equipment, and the shape of various secondary equipment graphic elements can be defined in detail in the <symbol> group.
步骤102，解析已有的一次设备的SVG一次接线图文件，并保存在内存中。Step 102, analyzing the existing SVG primary wiring diagram file of the primary equipment, and saving it in memory.
SVG文件本质上是XML文档，因此，在解析SCG一次接线图文件时遵循XML文档规范的定义，并保存在内存中。The SVG file is essentially an XML document, so when parsing the SCG primary wiring diagram file, it follows the definition of the XML document specification and stores it in memory.
步骤103，通过已解析的SVG一次接线图文件，识别出SVG一次接线图所属的变电站；具体的，电网公司建设的生产管理信息系统中维护有二次设备的台账信息，包括设备编码、所属变电站、功能位置等。通过已解析的SVG一次接线图文件，即可识别出接线图所属的变电站。Step 103, through the parsed SVG primary wiring diagram file, identify the substation to which the SVG primary wiring diagram belongs; specifically, the production management information system built by the power grid company maintains ledger information of secondary equipment, including equipment code, belonging Substations, functional locations, etc. Through the parsed SVG wiring diagram file, the substation to which the wiring diagram belongs can be identified.
步骤104，从生产管理系统的数据库台账中获取所述变电站内的二次设备与一次设备的关系，并将二次设备与一次设备的关系采用映射表保存在内存中；Step 104, obtaining the relationship between the secondary equipment and the primary equipment in the substation from the database ledger of the production management system, and storing the relationship between the secondary equipment and the primary equipment in the memory using a mapping table;
具体的，从生产管理系统的数据库台账中获取该变电站所拥有的二次设备及其与一次设备的关系，如A油色谱在线监测装置安装在甲变压器。将二次设备与一次设备的关系采用映射表保存在内存中。Specifically, the secondary equipment owned by the substation and its relationship with the primary equipment are obtained from the database account of the production management system. For example, the oil chromatography online monitoring device of A is installed in transformer A. The relationship between secondary equipment and primary equipment is stored in memory using a mapping table.
步骤105，根据二次设备与一次设备的关系，在SVG文件中的找到相对应一次设备的位置信息，对一次设备的位置信息进行逻辑计算得到二次设备的位置信息；Step 105, according to the relationship between the secondary equipment and the primary equipment, find the location information corresponding to the primary equipment in the SVG file, and perform logical calculation on the location information of the primary equipment to obtain the location information of the secondary equipment;
具体的，根据二次设备与一次设备的关系，在SVG文件中的找到相对应一次设备的位置信息，对此位置信息进行简单逻辑计算（如纵横坐标都偏移N个单位,N为大于等于2的自然数）得到二次设备的位置信息。二次设备的通用格式如下：Specifically, according to the relationship between the secondary equipment and the primary equipment, find the location information corresponding to the primary equipment in the SVG file, and perform a simple logic calculation on the location information (for example, both the vertical and horizontal coordinates are offset by N units, and N is greater than or equal to The natural number of 2) to obtain the location information of the secondary equipment. The general format for secondary devices is as follows:
<g><g>
<use x="二次设备横坐标" y="二次设备纵坐标" <use x="abscissa of secondary equipment" y="ordinate of secondary equipment"
xmlns:xlink=http://www.w3.org/1999/xlinkxmlns:xlink=http://www.w3.org/1999/xlink
xlink:href="引用名称"xlink:href="reference name"
xlink:type="simple"xlink:type="simple"
class="样式名"class="style name"
id="二次设备Id"/>id="secondary device Id"/>
</g></g>
步骤106，建立二次设备图形与SVG在线监测数据模型关系；Step 106, establishing the relationship between the secondary equipment graphics and the SVG online monitoring data model;
具体的，二次设备采集的实时数据上传到主站系统后都会建立相应的数据模型，如在实时数据库中采用测点编码来表示每个特定的采集数据。根据二次设备ID在数据模型中获取到该设备所采集数据的测点编码，并生成二次设备图形与在线监测数据模型的关系信息，通用格式如下：Specifically, after the real-time data collected by the secondary equipment is uploaded to the main station system, a corresponding data model will be established, such as using a measuring point code in the real-time database to represent each specific collected data. According to the secondary equipment ID, the measuring point code of the data collected by the equipment is obtained in the data model, and the relationship information between the secondary equipment graphics and the online monitoring data model is generated. The general format is as follows:
<metadata name="测点编码" <metadata name="measuring point code"
ObjectID="二次设备ID"ObjectID="secondary device ID"
Datatype="采集数据类型"/>Datatype="collection data type"/>
步骤107，在SVG在线监测数据模型修改并保存包含二次设备图元信息的新的SVG一次接线图文件；Step 107, modifying and saving a new SVG primary wiring diagram file containing secondary equipment graphic element information in the SVG online monitoring data model;
具体的，将保存在内存的一次接线图文件按顺序写入新的SVG文件，在图元定义的末段插入新的二次设备图元信息，在写每个一次设备图形时插入相应的二次设备图形信息，在文件结束</svg>之前写入二次设备图形与在线监测数据模型的关系信息。将新的SVG一次接线图文件替代旧的一次接线图文件。Specifically, write the primary wiring diagram files stored in the internal memory into a new SVG file in order, insert new secondary device graphic element information at the end of the graphic entity definition, and insert the corresponding secondary device graphics when writing each primary device graphic. Secondary equipment graphic information, write the relationship information between the secondary equipment graphic and the online monitoring data model before the end of the file</svg>. Replace the old primary wiring diagram file with the new SVG primary wiring diagram file.
步骤108，以新的SVG一次接线图文件，封装实时数据推送功能模块，配置服务端地址，实现对电网运行状态和电力设备运行状态的集成监控。In step 108, the new SVG primary wiring diagram file is used to encapsulate the real-time data push function module, configure the server address, and realize the integrated monitoring of the power grid operation status and the power equipment operation status.
需要说明的是，这里的集成在线监测数据监控方法可以采用与一次设备实时运行情况监控相同的方法实现。It should be noted that the integrated online monitoring data monitoring method here can be realized by the same method as the real-time operation monitoring method of primary equipment.
具体的，该集成在线监测数据监控方法是通过一个程序去订阅实时数据库的推送服务，当实时数据有变化时，实时数据库将变化的数据推送给此程序，此程序再刷新下一次接线图，新的数据就会展示在一次接线图上。Specifically, the integrated online monitoring data monitoring method is to subscribe to the push service of the real-time database through a program. When the real-time data changes, the real-time database will push the changed data to the program, and the program will refresh the next wiring diagram. The data will be displayed on a wiring diagram.
实施本发明，具有如下有益效果：Implement the present invention, have following beneficial effect:
