Philosophy and Practice of Classification and Hierarchization of Power Distribution Network Planning and Design Standard System

Abstract

The integration of distributed power sources and other new-type equipment to power distribution network places higher requirements on the planning of power distribution network. Due to lack of scientific and reasonable classification and hierarchization methods, overlap or even contradiction among China’s existing power distribution network planning and design standards is becoming increasingly severe. Based on the principles of standard classification and the existing standard system, a classification and hierarchization method suitable for the power distribution network planning and design standard system is proposed in this paper. The power distribution net-work planning and design standards are classified into five classes. And then, after analysing the content attributes of standards at each level and the relation of inclusion among standards at different levels, two hierarchization methods including Content Evaluation Method and Comparative Analysis Method are proposed to determine the level of a standard. Finally, this paper illustrated the effectiveness of the two methods by examples. These research results provided theoretical guidance and reference for the effective management and efficient application of standards and the establishment of a modern power distribution network planning and design standards system.
