Документ Possibilities of using PSS®SINCAL, ETAP, Powerfactory software for modelling electric power networks(Національний технічний університет "Харківський політехнічний інститут", 2022) Shevchenko, Sergey; Danylchenko, Dmytro; Kuznetsov, Dmytro; Qawaqzeh, Mohamed Zaidan; Miroshnyk, OleksandrThe article is devoted to modeling of electrical networks. The article discusses the positive and negative features of simulation programs. Special attention is paid to the principles of the program. The article discusses such programs as PSS®SINCAL from Siemens; ETAP from Operation Technology and PowerFactory from DIgSILENT GmbH. In the work, we considered the programs and decided that the most successful solution for working with the modeling of the electrical network and the impact of compensating devices on the electrical network would be the use of the PSS®SINCAL software from Siemens. For more than 20 years, the PSS®SINCAL platform has enabled engineers to solve various challenges of variable distribution, transmission and industrial power systems, including maintaining high reliability of supply and efficient integration of distributed energy resources. With PSS®SINCAL's modular platform, power system planning and operation engineers are supported throughout the entire workflow, from raw data import and network modeling (taking into account past, current and future conditions) through basic and advanced calculations to large-scale simulations and analysis protection, as well as other methods in the time and frequency domains. PSS®SINCAL is used in more than 100 countries by transmission and distribution planning engineers, protection engineers, consultants, power plant and industrial grid operators, operations planning engineers, IT specialists, researchers, and more. Thanks to its modular design, PSS®SINCAL is highly flexible and customizable. It offers a wide range of analysis functions for the planning, design and operation of power systems, allowing you to model and study: power quality, frequency stability, distributed generation interconnection, protection coordination, power restoration, economic design solutions and much more.Документ Introduction of state-of-the-art low-voltage distribution network devices(Національний технічний університет "Харківський політехнічний інститут", 2022) Holcsik, Peter; Morva, György; Bencsik, József; Shevchenko, Sergey; Danylchenko, Dmytro; Dryvetskyi, StanislavTrends towards the development of distributed generation involve a number of problems related to maintaining the quality of electric energy in medium and, especially, low-voltage networks. The article examines the impact of monitoring the quality of electricity of low voltage classes on the reliability of the electrical network. MSZ EN 50160 and Hungarian Energy and Utilities Regulatory Office (MEKH) standards are considered. In accordance with MSZ EN 50160, the main indicators of the quality of electric energy are considered, such as: frequency, voltage fluctuations, rapid voltage changes, dose of flicker, voltage dips, short-term voltage interruptions, long voltage interruptions, temporary overvoltages of industrial frequency, transient overvoltages between current-carrying conductors and voltage ground , harmonic voltage fluctuations, interharmonic voltage fluctuations. SAIFI and SAIDI are calculated according to the Hungarian Energy and Utilities Regulatory Office. The devices for monitoring the quality of electricity of low voltage networks are analyzed. The factors affecting the choice of the place of installation of monitoring devices are considered. It is presented how power quality monitoring systems can reduce the number of malfunctions in the 0.4 kV network, and the influence of monitoring systems on the quality of electric power in 6-35 kV networks is considered.
