A Novel SCD Validation Scheme Based on Information Classified Extraction and Semantic Strength Grading

Substation Configuration Description (SCD), containing all the configuration information of a smart substation, is generally non-standard at present. SCD validation is essential to the normal operation of a smart substation. Typically, SCD is composed of some implicit information, secondary circuits for instance, which is hard to validate directly. In existing works, developing software is the most common method to validate implicit information, however, is quite complicated and inflexible. Against this, this paper proposes a novel scheme merely utilizes programs for information extraction and assigns validation to XML Schema due to its descriptive ability of rules. In addition, SCD correctness definitions are graded by their semantic strength in order to proceed the validation level by level. It is concluded that the novel scheme is not only good at describing validation rules, but also universal to all the application scenarios.
