IEC 61850的狭义应用和广义应用

Specialized and Generalized Application of IEC 61850

依据语义约定具有偏序关系的论断,将IEC 61850的语义约定分为SCADA语义约定和变电站语义约定两个层次,相应地将对IEC 61850的应用分为广义应用和狭义应用。通过对IEC 61850技术体系的分析,指出狭义应用需要遵循一定的约束条件,IEC 61850中针对这种约束提供了明确的表示形式,这一形式恰恰成为IEC 61850除了技术体系的诸多特点外,优于IEC 60870-5- 103通信协议的本质,即IEC 61850可以明确地界定一个应用是否属于狭义应用,因此不会出现类似应用IEC60870-5-103时的不确定性。

Based on the judgment that semantic stipulations have semi-sequential relationship, this paper divides IEC 61850's semantic stipulation into two levels: SCADA semantic and substation semantic stipulation, also divides the application of IEC 61850 into generalized and specialized application accordingly. By the analysis to IEC 61850's technical system, this paper points out that specialized application must be restricted with some terms, IEC 61850 supplies a explicit denotation to these restrictions. Besides other good characteristics in IEC 61850's technical system, this denotation is the essence that IEC 61850 can overmatch IEC 60870-5-103, that is, IEC 61850 can estimate whether an application is specialized definitely and win through the uncertainty like using IEC 60870-5-103.
