所介绍的智能变电站SCD文件二维校验码校验方法，目的在于校验SCD文件的内容是否变化，对SCD文件进行版本管理。该方法是基于集合、函数、映射和变量比较的数学原理，首先将SCD文件的各组成部分、元素、数据属性分别抽象成集合、函数、变量，并用行号、列号分别统计元素、数据属性的个数。然后对集合、函数、变量进行二维定位、编码赋值，即将行号、列号唯一确定的数据属性的实际值作为校验量的赋值。最后通过校验校验量的赋值，得出SCD文件的校验结果。其中，校验量的唯一性，由对象标识Ref(引用)的唯一性保证。该方法能够可靠地校验SCD文件内容的差异性，校验精度精确到版本编号、数据属性的值、虚端子数目及外部/内部信号描述。该校验方法和校验流程为SCD文件的审核、修改、管理提供了技术手段，能有效地防止SCD文件的误改动。

The purpose of SCD file check method introduced in this paper is to check whether the SCD file details have been changed and to manage SCD file version. SCD file check method is based on mathematical principle of set, function, mapping and variable comparison. First, each component, element and data attribute are respectively abstracted into set, function and variable in this method. Row number and column number are used respectively to count the number of elements and the number of data attributes. Then, sets, functions and variables can be assigned by two-dimension positioning, which uses the actual values of uniquely identified data attributes as the assignments of variables to be checked. Finally, the check result of SCD file is obtained by checking these assignments. The uniqueness of these variables to be checked is ensured by the one of object identifier Ref. In this way, SCD file check method can reliably check the difference of SCD file details, to the accuracy of version number, value of data attribute, virtual terminal number and external/internal signal description. The check method and procedure in this paper provides technical measures for review, revise and management of SCD file, and avoids the error changing of SCD file effectively.
