Innovative earthing systems for electric power substations using conductive nanoparticles

Parallel Computing Aided Design of Earthing Systems for Electrical Substations in Non-Homogeneous Soil Models

An accurate design of grounding systems is essential to assure the safety of the persons, to protect the equipment and to avoid interruptions in the power supply. In order to attain these targets, it is necessary to compute the equivalent electrical resistance of the system and the potential distribution on the earth surface in fault conditions. In this paper, a numerical approach for grounding...

pattern recognition in maintenance data using methodologies data minitng (cade study isfahan regional power electric company)

فعالیت های نگهداری و تعمیرات اطلاعاتی را تولید می کند که می تواند در تعیین زمان های بیکاری و ارایه یک برنامه زمان بندی شده یا تعیین هشدارهای خرابی به پرسنل نگهداری و تعمیرات کمک کند. وقتی که مقدار داده های تولید شده زیاد باشند، فهم بین متغیرها بسیار مشکل می شوند. این پایان نامه به کاربردی از داده کاوی برای کاوش پایگاه های داده چندبعدی در حوزه نگهداری و تعمیرات، برای پیدا کردن خرابی هایی که موجب...

On Line Electric Power Systems State Estimation Using Kalman Filtering (RESEARCH NOTE)

In this paper principles of extended Kalman filtering theory is developed and applied to simulated on-line electric power systems state estimation in order to trace the operating condition changes through the redundant and noisy measurements. Test results on IEEE 14 - bus test system are included. Three case systems are tried; through the comparing of their results, it is concluded that the pro...

Electric Power Distribution Systems

Electric Power Systems Research

This book contains articles [1–22] that were accepted for publication in a Special Issue of Energies on the subject of “Electric Power Systems Research”. Customers request electric utilities to deliver electric power in a stable, reliable, secure, and sustainable manner from a generation system through transmission and distribution systems to end-users. Consequently, the need to develop advance...
