IEC 61850标准中SCL语言的几个实践应用问题探讨

讨论了IEC 61850系列标准中的变电站配置描述语言(SCL)在变电站自动化系统中对智能电子设备(IED)进行配置的若干实践问题,指出了该标准提供的SCL Schema中可能存在的某些前后一致性的问题及个别疏漏,包括:如何表达具有2种或以上功能约束值的数据属性;SBO等大写字母开头的属性名与Schema的属性名规范是否符合的问题;各种控制块元素的datSet属性的空值问题;ConfDataSet元素类型错误;简单单位枚举"SIUnit"中第38号和第62号重复使用W表示的问题.对这些问题给出了相应的解决方法和建议.

Discussion on Practical Issues of Substation Configuration Language in IEC 61850 Standards

According to the IEC 61850 serial standards and the syntax and semantic of substation configuration language (SCL), some practical issues about the application of SCL in terms of IED configuration in substation communication system are described. Some conflicting questions about SCL Schema are put forward and one or two careless omission is pointed out in the text. The problems include: How to express the data attribute, which has two or more kinds of function restraint values? The attribute name begins with the capital letter, i.e. attribute SBO, which is not conforming to the attribute name standard in Schema; The value of attribute datSet of all kinds of control block elements is null; The type of element ConfDataSet is wrong; In the simple unit enumerates "SIUnit", No. 38 and No. 62 repeatedly use W to express. The corresponding solving methods and proposals are given for the issues above.
