Considering that electric energy is a strategic and vital energy in daily life, the need for the stability of this energy in crises is a necessity. The most important solution to deal with crises caused by natural disasters is to put passive defense in the operation of electricity distribution networks. By using analytical techniques, it provides a platform for informed decision making in crisis. In this article, while examining the non-operating defense in the electricity distribution company of Chaharmahal and Bakhtiari province, we will provide a solution to overcome the crisis of heavy snowfall in Koohrang city. By implementing these solutions, we will compare the amount of undistributed energy in medium and weak pressure feeders in the critical months of Koohrang city and check the reliability of the network. پرونده مقاله

Analyzing accidents in order to identify their causes is one of the most important stages of accidents. With the help of descriptive-analytical analysis, this research deals with the evaluation, analysis and analysis of recurring incidents in the electricity distribution company of Chaharmahal and Bakhtiari province using Tribod-Beta and AHP methods. Considering the most important factor of human error, the Tribod-Beta method is one of the best methods in the analysis of incidents in electricity distribution companies. It has been drawn, to know the causes and problems related to the change, we will review the correction to prevent the occurrence of similar incidents. Considering the importance of the issue and confirming the non-interference of personal taste in the analysis of accidents, we weight the results using the AHP method. According to the obtained results, it can be said that non-observance of safety principles with 50% frequency and with the highest standard weight (0.5 and 0.1958) is one of the most risky causes of accidents in four frequent accidents. پرونده مقاله

Solar energy is one of the most important types of renewable energy in Iran. Solar systems are more acceptable in Iran due to their availability. In this article, the economic indicators of a Kw400 power plant in Iran are discussed. Regarding the investments of this sector, we have examined all the costs of the construction of the power plant and using the main analysis and profit analysis techniques, we evaluate and make economic calculations. Computer results have been evaluated as 25% and 30% discount and 40% inflation. The capital return rate of this power plant is 25.09% and the payback period of this power plant is 9 years. NPV with a 25% discount in the ninth year is 845.35 million Rials and with a 30% discount rate, it is 26809.88 million Rials. Also, the internal rate of return is calculated as IRR = 25.08%.
