Abstract
Objectives: The unwanted and unplanned outages due to faults occurred in electrical energy distribution systems are one of the main concerns of distribution companies. This paper examines this concerning. Methods/Statistical Analysis: This paper examines about ninety outages in related to the medium pressure power lines in second region of Bushehr over twomonth period. Findings: It has identified faults caused by power outages, and the time of outage for each fault is extracted in all regions of the primary data obtained from the power events. Then, by determining the cost function with the purely economic factors, are obtained the costs of each fault individually. In the following, for each fault are provided a series of preventive overhauls or preventive recommendations. Until increasing the system’s trustworthiness, the operating costs of unwanted faults are completely eliminated or minimized. Application/Improvements: The application of this paper is that examines the roles of preventive major maintenance in the costs of electric energy distribution companies. Keywords: Cost Function, Electric Energy Distribution Companies, Energy Not Served (ENS), Preventive Maintenance, Unplanned Outage
Highlights
Maintenance performing on power distribution networks is one of the key processes in managing power distribution systems
Since investments in maintenance performing depending on the type of power outage is diverse and different
In the two-month period reviewed in this article, there has been a premature loss of consciousness in electric district 2 of Bushehr[1]
Summary
Maintenance performing on power distribution networks is one of the key processes in managing power distribution systems. Maintenance performing seem to be obvious and every day, but by examining the constraints and objective functions, we face a complex problem called the maintenance planning to make maximum productivity. The most important constraint is its maintenance management is its finished price and Rial[1] share in the sale of electricity energy. Since investments in maintenance performing depending on the type of power outage is diverse and different. The high number of equipment of distribution system and the investment constraints make it impossible to do all maintenance, so prioritizing will be a very important part in the planning of maintenance. The developmental backlogs and maintenance in power distribution networks, the culture of network use, urban social culture in dealing with urban facilities, and the planning way of all and all have a very serious impact on the planning of preventive maintenance
