Abstract

This chapter presents a FRTHC for the MMC-based HVDC transmission system. The FRTHC is made up of four loops of cascading SCUs. Each SCU operates in a switching manner between a BBFC and a PI control loop. The BBFC is responsible for exploring the full control power of each control loop, with three-value control commands with the maximum magnitude. A state-dependent switching law is designed for each SCU to obtain the structural stability of SCUs. Simulation studies were carried out to evaluate the fault ride-through performance of the FRTHC.
