fault location in power distribution networks using matching algorithm
چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
Distribution System Topology Detection Using Consumer Load and Line Flow Measurements
We present a topology detection method combining smart meter sensor information and sparse line measurements. The problem is formulated as a spanning tree identification problem over a graph given partial nodal and edge power flow information. In the deterministic case of known nodal power consumption and edge power flow we provide sensor placement criterion which guarantees correct identificat...
متن کاملOutage Detection in Power Distribution Networks
Outage detection and management has been a long-standing problem in power distribution networks. Outages are caused by protective devices closing off a part of the network to automatically isolate it. Usually, a short circuit fault will trigger this protective operation. We employ the term outage detection to denote the task of finding the status of the protective devices, and the term fault de...
متن کاملFeeder Topology Identification using Consumer Load and Line Flow Measurements
Advanced control of distributed energy resources at the consumer level requires full situational awareness of the distribution system. This is typically performed by a topology identification and state estimation. In a distribution system, the topology is usually unknown since it depends on switch configurations on the network. In the case of residential feeders, switches may be passive compone...
