Hydroelectric Power Plants

Countries need to develop sustainable energy policies based on the principles of environmental sensitivity, reliability, efficiency, economy and uninterrupted service and to maintain their energy supply in order to increase their global competitiveness. In addition to this impact of sustainable energy supply on the global world, maintenance processes in power plants require high costs due to allocated time, materials and labor, and generation loss. Thus, the maintenance needs to be managed within a system. This makes analytical and feasible maintenance planning a necessity in power plants. In this context, this study focuses on maintenance strategy optimization which is the first phase of maintenance planning for one of the large-scale hydroelectric power plants with a direct effect on Turkey's energy supply security with its one fifth share in total generation. In this study, a new model is proposed for the maintenance strategy optimization problem considering the multi-objective and multicriteria structure of hydroelectric power plants with hundreds of complex equipment and the direct effect of these equipment on uninterrupted and cost-effective electricity generation. In the model, two multi-criteria decision-making methods, AHP and COPRAS methods, are integrated with integer programming method and optimal maintenance strategies are obtained for 571 equipment.

Hydroelectric Power Plants

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.

The One

When the first large-scale hydroelectric power plants were built in Sweden at the beginning of the twentieth century, the waterfall became a twofold symbol of the Swedish nation. On the one hand, the harnessed waterfall promised unlimited energy and economic growth, and thus turned into a unifying symbol of a national productive landscape. On the other hand, the unharnessed wild waterfall, to be enjoyed by tourists seeking refuge from the modern industrial world, became a symbol of a national recreational landscape. This situation, however problematic, did not result in conflict. Taking a look at the first two state-built water power plants in Sweden, I trace how the two contrasting concepts of landscape were harmonized within public discourse. I demonstrate how engineers, architects, conservationists, tourist organisations, and journalists together produced a broad public acceptance of the drastic changes in the national landscape brought about by the construction of these power stations.

The Southeastern Anatolia Project (GAP), encompassing 27 dams and 19 hydroelectric power plants, is a large-scale water management program aiming at an increase in domestic electricity production and the development of vast irrigation schemes for agriculture. In spite of numerous benefits experienced in the area, there is also a multitude of impacts observed on the environment. The Coruh River is the longest river of the East Black Sea region and is of high economic importance to Turkey because of its largely exploitable hydropower potential. The Coruh project consists of 27 planned dams and hydroelectric power plants. The planned dams have the potential to cause serious environmental effects in upstream Turkey and downstream Georgia. Equitable, rational, and optimal utilization of transboundary water resources can be achieved through a scientific study, which will determine the true water needs of each riparian country. A precise assessment is needed of the economic, ecological, and social problems on the basis of the environmental impact and cumulative effect assessment reports.

In this paper have been considered the basic approaches and main principles of geoengineering. The “geoengineering” term transformation, as well as the term’s specifications of use in the Russian-language scientific literature, and the application area have been demonstrated. In connection with the growing biosphere problems, it has been proposed to classify mining and global pollution (i.e. pollution of atmosphere, hydrosphere and soil) as geoengineering. Special attention has been paid to the possible risks of geoengineering (including at large reservoirs of hydroelectric power plants), and the necessity for detailed study before launching of large-scale projects. The UN approach to geoengineering management has been characterized, and the main principles of geoengineering regulations have been presented. An extended classification of geoengineering technologies has been proposed.
