Introduction

Introduction

High Voltage Direct Current (HVDC) transmission is revolutionizing the way power is delivered over long distances and across borders. As the demand for renewable integration, grid interconnection, and energy efficiency grows, HVDC systems offer unmatched benefits in bulk power transmission, lower losses, and voltage control. Training Course on High Voltage DC (HVDC) Transmission Systems explores the core principles, technologies, control mechanisms, and applications of HVDC—from classic line-commutated converters (LCC) to next-generation voltage-source converters (VSC).

Participants will gain a deep understanding of converter station design, system modeling, power electronics, and dynamic control strategies essential for planning, operating, and maintaining HVDC systems. Emphasis is placed on real-world case studies, hands-on simulations, and the role of HVDC in supporting smart grid development, offshore wind farms, and cross-border power trading. Through this course, energy professionals will be equipped to lead projects in grid modernization, resilience, and global energy connectivity.
