Book Description
A stand-alone digital relay was designed and implemented that can be modified quickly to accommodate the protection of different types of transformers by changing the software only. This paper presents the real-time experimental results of five selected algorithms implemented using this digital relay. The algorithms used include discrete Fourier transform, Walsh functions, rectangular transform, finite impulse response filtering, and least square algorithm.
Digital Protective Schemes for Power Transformer
Author: Dharmesh PatelPublisher: Springer Nature
ISBN: 9811567638
Category : Technology & Engineering
Languages : en
Pages : 217
Book Description
This book provides a comprehensive overview of protection schemes used for power transformers and describes the internal fault conditions and external abnormalities that may disrupt the operation of a power transformer. It also highlights the issues of current protective schemes, which pose several challenges in terms of the detection of internal faults and abnormalities, including computational burden, reduced accuracy, difficulty to implement, increased cost, computational complexity, impermeability to high resistance faults (HRF), and malfunction in conditions like cross-country fault. To address these problems, the book develops an effective novel transformer protection scheme that can eliminate all the said difficulties using an innovative algorithm. Given its scope, it is a useful resource for researchers and practitioners working in the field of power system protection, allowing them to design novel protection schemes, and providing insights into the hardware validation of developed technique.

Advancement in Power Transformer Infrastructure and Digital Protection
Author: Nilesh ChothaniPublisher: Springer Nature
ISBN: 9819938708
Category : Electric power systems
Languages : en
Pages : 331
Book Description
This book provides an overview of a power transformer infrastructure and comprehensive digital protection of it. It presents various protective methodologies available to protect the transformer from disturbances by taking care of mal-operation due to external disturbances and providing fine protection to the transformer. Though there are many protection methodologies available in the practice. However, these existing methodologies may mal-operate during external disturbances such as inrush, over-fluxing and short circuits. Hence, further research is needed in addition to the existing methods of protection in terms of more fault prediction accuracy, speedy operation, and lower protection cost with zero error in the detection of faults. The book will be useful reference for practitioners from academia and industrial applications. .
