چکیده
In the paper different approaches used for creation of electric power transformers are discussed and main types of their mathematical models and macromodels are described. Mathematical model of transformer is created in the hybrid coordinate basis, and macromodel of the power transformer is developed using the “black box” approach in the form of state space equations, the features of such type models usage are analyzed. Streszczenie. W artykule opisano alternatywne podejścia do konstrukcji transformatorów i podstawowe rodzaje ich matematycznych model i makromodeli. Omówiono tworzenie matematycznego model transformatora w hybrydowym układzie współrzędnych i budowę makromodelu w postaci równań stanu z wykorzystaniem podejścia typu ,,czarna skrzynka”. Przedyskutowano własności opracowanych modeli. (Matematyczne modele i makromodele transformatorów mocy)

Different Electric Vehicle Charging Strategies to avoid Reducing the Insulation Oil Lifetime of Distribution Transformers
Abstract: The widespread presence of uncontrolled electric vehicles causes overloading of distribution network equipment. One of these equipments is distribution transformer, which should pay attention to overloading and reducing lifetime of this equipment due to charging of electric vehicles. First, strategies have been proposed to investigate the effect of electric vehicle penetration level a...
متن کاملThe objective of this project is to develop new mathematical models and optimization methods for robust planning of electrical
We describe new analytical techniques to help mitigate the disruptions to electric power grids caused by terrorist attacks. New bilevel mathematical models and algorithms identify critical system components (e.g., transmission lines, generators, transformers) by creating maximally disruptive attack plans for terrorists assumed to have limited offensive resources. We report results for standar...
متن کاملLong-term Planning of Optimal Placement of Distribution Transformers to Improve Reliability and Power Quality with the Approach of Reducing Costs and Losses
One of the most critical and complex issues in long-term planning of distribution networks is the optimal placement of distribution transformers. In this paper, the optimal placement of distribution transformers was investigated based on a complete and multi-objective function. In the proposed method, location, optimal capacity, and the service area are determined by minimizing costs (investmen...

This paper presents a new method for evaluation and simulation of inrush current in various transformers using operational matrices and Hartley transform. Unlike most of the previous works, time and frequency domain calculations are conducted simultaneously. Mathematical equations are first represented to compute the inrush current based on reiteration and then Hartley transform is used to stud...
