Given the increasingly busy railway networks, increased axle loads, and railway speeds, modern railways and urban transport systems require smart and energy-efficient traction power supply products and solutions to ensure safe, reliable, and environmentally sustainable operations. Based on the latest development and achievements of China’s traction power supply system, Smart Traction Power Supply Systems for High-speed Railways focuses on the latest research into smart traction power supply systems. Starting from the concept of smart technologies, it describes the structure and functions of smart traction power supply systems, including smart power supply and transformation facilities, smart power supply operation and maintenance management systems, smart power supply dispatching systems, and high-speed communication networks. This book covers both theory and the implementation, methods, and case studies of wide area protection, selfhealing reconstruction, fault prognosis, health assessment, and power supply dispatching.

This book delves into the innovative realm of wound core transformers designed for high-voltage power grids, moving beyond the traditional laminated core structures prone to magnetic flux leakage and energy dissipation. Through a novel enclosed wound core design that eliminates joints and corners, it presents a transformative approach that minimizes leakage and enhances the electromagnetic performance of transformers. This book not only addresses the technical challenges and solutions in transformer design but also marks a significant step forward in the pursuit of energy efficiency and performance optimization in electrical power systems. Targeting a specialized audience of professors, scholars, and graduate students engaged in transformer energy-saving optimization and related research fields, it offers an in-depth exploration of the complete loss calculation, innovative manufacturing processes, and testing technologies of large-scale wound core transformers.
