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...

Supply development is a major challenge in electric power industry. In order to fulfill this need, and regarding complexities in the energy sector, a comprehensive model such as system dynamics is zimperative. The purpose of this study is to reach this model. The performance of the model was based on the selection of a technology which could give way to the lowest total cost of genera...

Transformation of the monopolistic electric industry into a competitive and free market system is underscored by the wide price variation of electricity. To address price variation, the Federal Energy Regulatory Commission has proposed the development of fair competition in the wholesale power market as a first step toward full deregulation of the industry. This paper will discuss the steps tha...
