HVDC Scheme: Challenges, Features, and Advanced Operational Strategies, a Customized 2-Day Course by Tonex
This 2-day specialized course delivers an in-depth exploration of High Voltage Direct Current (HVDC) systems, focusing on the latest challenges, features, and advanced operational strategies. Designed for power system engineers, grid planners, and HVDC system integrators, the course provides comprehensive knowledge of Line-Commutated Converter (LCC) and Voltage-Source Converter (VSC) technologies, as well as detailed insights into system modeling, control, and fault management.
Participants will learn the building blocks of HVDC schemes, from converter stations and filters to ancillary control systems such as Frequency Control (FC) and Dynamic Reserve Power Sharing (DRPS). Real-world scenarios, system studies, and case-based exercises guide learners through equipment interactions, risk assessments, interoperability, and the role of HVDC in supporting modern grid stability.
Special emphasis is placed on understanding how HVDC contributes to inter-regional power transfer, grid resilience, and future grid integration with renewable energy and energy storage systems.
By the end of this course, participants will be equipped to confidently specify, analyze, and operate HVDC schemes, while staying informed on the evolving landscape of advanced HVDC technologies and applications.
