The Role of Preventive Major Maintenance in the Costs of Electric Energy Distribution Companies


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.
