Fault Classification and Localization Scheme for Power Distribution Network

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...

Time-frequency Distribution for Automatic Fault Classification in Power Electronics

A new method of fault analysis and detection by signal classification in industrial frequency converters is presented. The WignerVille time frequency distribution is used to produce the representation of the signal and the probabilistic neural network as a classifier. The accuracy and robustness of the proposed method is investigated on signals obtained during the different fault mode operation...

Fault Classification and Localization in Power Systems Using Fault Signatures and Principal Components Analysis

A vital attribute of electrical power network is the continuity of service with a high level of reliability. This motivated many researchers to investigate power systems in an effort to improve reliability by focusing on fault detection, classification and localization. In this paper, a new protective relaying framework to detect, classify and localize faults in an electrical power transmission...

A Dynamic Fault Classification Scheme

In this paper, we introduce a novel and simple fault rate classification scheme in hardware. It is based on the well-known threshold scheme, counting ticks between faults. The innovation is to introduce variable threshold values for the classification of fault rates and a fixed threshold for permanent faults. In combination with field data obtained from 9728 processors of a SGI Altix 4700 compu...
