Since the essence of the research on this project is numerical modeling, the basic research equipment is computer equipment. There are desktops and laptops in the researchers’ study rooms. In addition, there are a total of thirteen desktops in the Electromagnetic Compatibility Laboratory (A323). To test numerical results, we use the MultiFields+ software package (part of the CDEGS software package from Safe Engineering Services & Technologies ltd. based in Canada). MultiFields is a software package for numerical modeling of electromagnetic phenomena. For the same purpose, we use the software package XGSLab product from SINT Ingegneria based in Italy as well as the software package EMTP RV product from EMTP Alliance based in Canada. In the Research Laboratory (A322) we have equipment for measuring ground resistance and geoelectric sounding of the soil as well as equipment for measuring the low-frequency electric and low-frequency magnetic fields of electric power lines and plants. In addition, in the same laboratory we have a device for measuring static electricity, a device for testing the quality of electric power and a device for testing the dielectric strength of materials.
There is a constant need for a theoretical understanding of electromagnetic phenomena in the electric power system and its environment, and the need for the most accurate numerical modeling of these phenomena. Of particular importance are electromagnetic phenomena during the stationary operation of the power system, electromagnetic phenomena in the event of failures, electromagnetic phenomena caused by switching operations and electromagnetic phenomena caused by lightning strikes. The essence of the research is the development of new algorithms and the improvement of existing algorithms for numerical modeling of electromagnetic phenomena in the power system. Most of the planned research is a continuation of many years of research in this area. The first important goal of the research is to develop a new complete electromagnetic model for harmonic and transient analysis of grounding systems in a horizontally stratified multilayer medium. Another important goal is the further development and improvement of the originally developed quasi-static electromagnetic model for the computation of low-frequency electric and magnetic fields of electric power lines and plants. The third important goal is the further development and improvement of the originally developed electromagnetic model for the computation of the ground fault current distribution, based on the application of the finite element technique. The fourth important goal is the development of numerical high-precision algorithms for computing the self and mutual per-unit-length impedance of infinitely long mutually parallel conductors with a return path through a multilayer ground. The fifth important goal is the further development and improvement of originally developed numerical models for the computation of electromagnetic transients in linear and nonlinear time-domain networks using a combination of finite element method and the method of characteristics. The sixth important goal of the research is the further development and improvement of numerical algorithms for the analysis of transient stability in power systems, with special emphasis on the development and improvement of numerical algorithms for optimizing the operation of hydraulic digital turbine governor.
