Abstract
In this study, maintenance planning problem is handled in one of the hydroelectric power plants which directly affect Turkey’s energy supply security with a fifth share in the total generation. In this study, a result is obtained by taking into consideration the multi-objective and multi-criteria structure of the maintenance planning in the hydroelectric power plants with thousands of complex equipment and the direct effect of this equipment on uninterrupted and low-cost electricity generation. In the first stage, the risk levels of the equipment in terms of the power plant are obtained with the combination of AHP (Analytical Hierarchy Process) and TOPSIS (technique for order preference by similarity to ideal solution) which are frequently used in the literature due to their advantages. Department-based maintenance plans of all equipment for periodic and revision maintenance strategies are formed by integrating these values into the time allocated for maintenance and the number of employees constraints. As a result of the application of this methodology which is designed for the first time in the literature with the integration of multi-criteria decision-making methods for the maintenance planning problem in a hydroelectric power plant, all elements that prevent the sustainable energy supply in the power plant are eliminated.
Highlights
Electricity generation plants are large-scale infrastructure investments with a comprehensive goal of sustainable energy supply
The planned maintenance plans were operated for 2 years and as a result of these efforts for the sustainable energy supply of the power plant, a 100% improvement was achieved in the production stops due to the failure to manage the maintenance in a system
The TOPSIS method was developed by Hwang and Yoon [53] in 1981 and is a method commonly used in real life multi-criteria decision problems
Summary
Electricity generation plants are large-scale infrastructure investments with a comprehensive goal of sustainable energy supply. The broad scope of this aim is to realize uninterruptedly, reliably, efficiently, economically and environmentally sensitive electricity production simultaneously In this facility, in the process of using economic life at the highest possible level without departing from the sustainability perspective, the operation of the facilities in accordance with the operating directives given by the manufacturing companies and the rational application of the two main pillars. In the case of continuous production systems such as electricity generation facilities where this work is carried out, the cost of production loss, which is the result of production stops due to faults, and the time required for maintenance, manpower and material requirements, is a process with a high cost of maintenance. The study was completed by presenting the results obtained in the sixth and last part of the study and suggestions for future studies
