Topology Identification Algorithm of Low-voltage Distribution Transformer Area Based on Conservation of Electricity
摘要
Abstract
The topology structure of low-voltage distribution transformer area plays an important role in line loss analysis,fault location,and system operation level. Aiming at the current problem of inaccurate topology information in low-voltage distribution transformer area,a topology identification algorithm based on conservation of electricity is studied. Firstly,for the distribution side,the topology structure of branch switch is determined based on the ergodic operation of the identified node's electrical quantity correlation algorithm;Secondly,for the user side,the connection between the meter box and the user meter is calculated based on the convex optimization algorithm,and the abnormal judgment results are corrected by clustering the voltage data. Finally,the actual data collected from the site are used to analyze the low-voltage distribution transformer area,which includes 1 master meter,12 branch meters,9 meter boxes and 108 user meters. The results verify the effectiveness and reliability of the proposed algorithm.关键词
