Intelligent Setting Package Based on Setting Value Graining and Common Library

摘要

In-depth analysis and study of six unified device fixed value and setting principle, combined with the application of the device setting in the relay protection setting calculation software. Intelligent setting package with protection device common libraries and granular fixed value was designed and developed based on database technology in relay protection setting calculation software. The common setting value of line, transformer and bus protection was summarized in protection device, and the value of reference was support in different protection device. Protection device model was split to header, fixed value area and footer with setting value graining. Then the repeated established work of header, fixed value area and footer in different areas was avoided. Finally, this paper design and development of intelligent setting package is applied to the field setting value calculation, the results show the practicability, flexibility and scalability of the function of this article.
