Voltage Level Scheming And Feeding Modes Selection Of Urban Distribution Network

Rational scheming of voltage levels and feeding modes has a strong influence not only on power system structure and distribution, but also on the designing of equipments in power system. In this paper, the method and process of selecting appropriate voltage level and feeding mode are proposed in detail.Firstly, on the basis of analyzing the essentiality for rational scheming of voltage levels in distribution networks, voltage level selecting method and processes are introduced, in which the economic evaluation system and technical evaluation system for choosing voltage level are proposed respectively. Furthermore, based on analytic hierarchy process (AHP) and fuzzy comprehensive evaluation, a method to select distribution network feeding modes is proposed, in which the complicated feeding mode selection is simplified, the structural diagram of AHP and the membership function that matches the features of evaluation attributes are built, and a comprehensive evaluation system for distribution network planning is constructed.Besides, the above-mentioned methods are applied to two practical projects—Voltage Level Selection of MV Distribution Network for A Certain Place in Shanghai and The Feeding Mode Selection of A Certain...
