| 摘要: |
| 把可扩展标记语言(XML)应用于电力系统中,利用其利于跨平台的数据交换和系统的互操作、良好的数据存储格式、可扩展性、高度结构化等优点,很好地解决了异构平台之间的数据传输。详细介绍了面向设备的XML描述方法以及用XML描述电力系统信息的方法。以变压器为例,说明了XML Schema制定及相应的XML描述,其步骤包括:进行XML类型声明,包括版本和编码形式;Schema声明语句,包含Schema命名空间的声明;声明一个元素名为Substation的用户自定义的复杂数据类型,并通过嵌入复杂数据类型的定义实现用户自定义的复杂数据类型;声明一个Transformer元素;各个独立子元素的声明。 |

| Abstract: |
| Features of XML(eXtensible Markup Language) are applied for data transfer between isomerous systems in power systems,such as inter-platform data exchange,inter-system operation,better data storage format,expansibility,highly structured file and so on.The device-oriented XML description and the way to describe electric system information with it are introduced.Taking transformer as an example,the XML Schema constitution and its XML description are presented.Steps are as follows:declaration of XML type,including its version and code format;declaration of Schema statement,including name spaces;element declaration of user-defined complex data type named as Substation and its implementation by inserting its definition;element declaration named as Transformer;declaration of each independent sub-element. |
