Optimal load distribution estimation for fault location in electric power distribution systems

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...

State Estimation for Load Allocation in Distribution Power Systems

Considering the large number of customers, local online monitoring is not conceivable. Alternatively, customers’ load could be estimated using some measurements in the main station and also on important points of power grid. Therefore, the customers’ load allocation is a consequential part in automated distribution power systems. In this paper, the load allocation is developed using average dem...

Fault Type Estimation in Power Systems

This paper presents a novel approach for fault type estimation in power systems. The Fault type estimation is the first step to estimate instantaneous voltage, voltage sag magnitude and duration in a three-phase system at fault duration. The approach is based on time-domain state estimation where redundant measurements are available. The current based model allows a linear mapping between the m...

Fault Location Techniques for Distribution Systems

Faulted lines must be repaired and returned to service in the shortest possible time to provide reliable service to the customers. Fault locators provide estimate for both sustained and transient faults. Transient faults cause minor damage that is not easily visible on inspection. Fault locators help identify those locations for early repairs to prevent recurrence and consequent major damages. ...
