Nonlinear Model of Tape Wound Core Transformers
Recently, tape wound cores due to their excellent magnetic properties, are widely used in different types of transformers. Performance prediction of these transformers needs an accurate model with ability to determine flux distribution within the core and magnetic loss. Spiral structure of tape wound cores affects the flux distribution and always cause complication of analysis. In this paper, a...
متن کاملApplication of ANN Technique for Interconnected Power System Load Frequency Control (RESEARCH NOTE)
This paper describes an application of Artificial Neural Networks (ANN) to Load Frequency Control (LFC) of nonlinear power systems. Power systems, such as other industrial processes, have parametric uncertainties that for controller design had to take the uncertainties in to account. For this reason, in the design of LFC controller the idea of robust control theories are being used. To improve ...
متن کاملNew Trends in Noise Reduction of Power Transformers
In the electrical network power transformers play a key role in transmission and distribution of electrical energy. Noise emissions on power transformers will be supervised in Germany strictly according to the German Federal Immission Control Act (Bundes-Immissionsschutzgesetz) [1] and are a challenge for the utilities to fulfill the therein stated requirements. When in operation power transfor...
متن کاملHarmonic Modeling of Inrush Current in Core Type Power Transformers Using Hartley Transform
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...
