| Abstract [eng] |
The main goal of the master's final project is to investigate possibilities to use the dismantled energy units and their equipment for the provision of reactive power and voltage management services, and to carry out a study of the economic efficiency in the installation. The final project consists of three main parts: review and analysis of scientific literature and research methodology, feasibility study for the use of dismantled units of reactive power and voltage management, research results and conclusions. Performed literature analysis provides an overview for the usage of the old thermal power units for the reactive power and voltage management possibilities. Also, presented main principles of the investment project management and evaluation, as well as the cost-benefit analysis method applied for determing the efficiency of the investment project. Theoretical aspects revealed the importance of reactive power and voltage management for the power system. The exploratory part presents a detailed technical analysis of the current situation, which showed the technical possibilities of the application to work in the synchronous compensator mode. Using the cost-benefit analysis method, the economic efficiency of the synchronous compensator was determined. Based the research findings conclusions are presented on possibilities using the disassembled energy units and their equipment to provide reactive power and voltage management service and the economic efficiency of the use. |
