主 题：Feeder automation Equipment layout optimization Power outage time Explicit expression Mixed integer quadratic programming model Functional failure probability of equipment
摘 要：In feeder automation transformation there are difficulties in equipment and location *** help with this,an optimal layout model of feeder automation equipment oriented to the type of fault detection and local action is *** analyzes the coordination relationship of the three most common types of automation equipment,i.e.,fault indicator,over-current trip switch and non-voltage trip switch in the fault handling process,and the explicit expres-sions of power outage time caused by a fault on different layouts of the above three types of equipment are *** constraints of power supply reliability and the goal of minimizing the sum of equipment-related capital invest-ment and power interruption cost,a mixed-integer quadratic programming model for optimal layout is established,in which the functional failure probability of equipment is linearized using the 3δprinciple in ***,the basic characteristics of the proposed model are illustrated by different scenarios on the IEEE RBTS-BUS6 *** can not only take into account fault location and fault isolation to enhance user power consumption perception,but also can guide precise investment to improve the operational quality and efficiency of a power company.
