"This textbooks demonstrates the application of software tools in solving a series of problems from the field of designing power system structures and systems. It contains four chapters : The first chapter leads the reader through all the phases necessary in the procedures of computer aided modeling and simulation. It guides through the complex problems presenting on the basis of eleven original examples. The second chapter presents application of software tools in power system calculations of power systems equipment design. Several design example calculations are carried out using engineering standards like MATLAB, EMTP/ATP, Excel & Access, AutoCAD and Simulink. The third chapters focuses on the graphical documentation using a collection of software tools (AutoCAD, EPLAN, SIMARIS SIVACON, SIMARIS DESIGN) which enable the complete automation of the development of graphical documentation of a power systems. In the fourth chapter, the application of software tools in the project management in power systems is discussed. Here, the emphasis is put on the standard software MS Excel and MS Project."

This study aims to analyse the tension force and production efficiency of a sorghum drilling machine to support eco-friendly systems. Sorghum, as a drought-resistant food crop, has significant potential in sustainable agriculture. The research employs an experimental approach to measure the tension force of the drilling machine at various speeds and drilling depths. Additionally, production efficiency is evaluated by comparing the machine's output to energy consumption and operational time. The results indicate that optimizing the machine parameters can enhance efficiency and reduce environmental impact. This finding is expected to contribute to the development of more sustainable agricultural technologies and support the implementation of eco-friendly farming practices. Furthermore, this research includes a comparison with conventional drilling machines in the context of eco-friendly systems. The sorghum drilling machine is designed with more efficient technology, resulting in lower tension force and increased productivity. The study measures the machine's performance across different speeds and drilling depths, while also assessing production efficiency through energy consumption and operational time analysis. The findings show that the sorghum drilling machine not only optimizes output with lower energy consumption but also reduces the carbon footprint compared to conventional drilling machines. These results make a significant contribution to the advancement of sustainable agricultural technology and support more eco-friendly farming practices. "
