Modern Traction Power Supply

This book distills two decades of academic and scientific advancements in railway traction electrification. It provides comprehensive coverage of negative-sequence control, including a single-phase comprehensive compensation model, and details co-phase power supply strategies for traction substations via reactive-power schemes designed to minimize capacity requirements and standard-group (?) combined compensation, as well as active-power schemes featuring single-phase and single-/three-phase combined designs with AC-DC-AC converter control. Furthermore, the text explores the expansion of power-supply modes through bilateral continuous and intelligent supply, traction-network voltage-quality assurance and a co-phase AT scheme to enhance capacity and utilization. It also addresses protection and monitoring via sectional protection and intelligent monitoring/control to isolate faults and streamline operations and maintenance (O&M), and green power initiatives leveraging new energy and zero-carbon continuous-supply technologies. Finally the book presents forward-looking proposals for rail-transit traction, including 3kV power-frequency AC rolling stock and intelligent power supply/control for unmanned driving. This book serves as a primary resource for graduate and doctoral students specializing in Railway Traction Electrification and Automation.
