Abstract
In this paper, a simple method for placing an optimal number of recloser is presented. The algorithm is solved using genetic algorithm as the optimization method. 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 used in power systems optimization problems. Distribution network automation is one of the aspects tackled using GA. However ,the methodologies used to improve the reliability of radial distribution feeders are reviewed. The reliability improvement are demonstrated for typical distribution feeder layouts. determined. The method enjoys the simplicity of conFigure uration, accuracy of the results and reduction of the time consuming. The obtained results also show the applicability of the algorithm
Highlights
The necessity to provide reliability in the distribution system and in power can be defined as the system’s capability in generation, transmission and distribution of electricity energy to the consumers
That is a try and error performance to detect of the errors that causes sever stress and creation of special transient modes in network and causes the reduction of station’s key life time. so, in order to prevent unsuccessful switching from transmission and high distribution system and to increase from transmission and high distribution systems and to increase the reliability in transmission of electrical energy and establishing its continuity and creating stability in system of medium voltage lines, a soft were installation called recloser is required that should meet following cases:
In this paper we study one of the protective device in electrical power system,this device can recognize of unusual states for example transient errors can do best activity,other than the passing fault have important rule in position and act of recloser
Summary
The necessity to provide reliability in the distribution system and in power can be defined as the system’s capability in generation, transmission and distribution of electricity energy to the consumers. Halt frequent (frequency of occurrence of halts and interrupts), the time period of each halt and the rate of consumption each consumer needs in the lake of consumer service and lake of feeding system are the main factor s to judge about systems reliability. Many factors are important in the determining the reliability of a system that some of them are controllable. Other factor are important in reduction of network s reliability such as disorder and distribution by third part ,atmospheric and environmental condition like temperature, humidity ,environmental, and air pollution, wind, rain, rain, snow ,ice, and thunderbolt. Recloseer’s positioning in order to reduce transient interruption and reduction of undistributed energy and satisfaction of customers. This report deals with second view of recloser positioning that is reduction of transient interruptions and reduction in undistributed energy and satisfaction of customers. This paper concern with the collection of total average frequency of occurred errors in the region
