In this paper a best method of fault locating in a radial power distribution system is discussed. The history associated with fault occurred in power system can be effectively used as a strong database. This database will act as the trainer to the fuzzy expert system. In this paper methodology based on fuzzy expert system is discussed for assistance to the operators for easy fault detection.Ele...
This paper presents a simple three phase load flow method to solve three-phase unbalanced radial distribution system (RDS). It solves a simple algebraic recursive expression of voltage magnitude, and all the data are stored in vector form. The algorithm uses basic principles of circuit theory and can be easily understood. Mutual coupling between the phases has been included in the mathematical ...
the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
This paper presents a simple three phase load flow method to solve three-phase unbalanced radial distribution system (RDS). A three phase load flow solution with considering most of load modeling is presented which has good convergence property for any practical distribution networks with practical R/X ratio. It solves a simple algebraic recursive expression of voltage magnitude, and all the da...
The majority of outage events experienced by customers are due to electrical distribution failures. Increasing network reliability is a necessity in order to reduce interruption events. Distribution network automation can trim down outage events and increase system reliability. Network automation has to be done using optimization approaches. Genetic Algorithm (GA) is a relatively new technique ...
In recent years the use of renewable energy sources (RES) by many power grid companies worldwide has increased significantly. The trend towards RES is mainly due to environmental issues and rising fuel prices associated with conventional electricity generation. This paper introduces a hybrid approach find optimal location size distributed generations (DG) in radial distribution system (RDS). pr...
