RTDS-based modeling for full-process simulation of two types of HVDC systems

摘要

The characteristics of DC system control and protection programs are analyzed for ABB and Siemens HVDC systems. The detailed model for full-process simulation of steady-state and transient response of HVDC system is established through combining RTDS component library and user-defined modeling by CBuilder. Simulation of steady-state and transient response of HVDC system is performed based on the model. The accuracy of the model is verified through comparison of the simulation results and the practical response of HVDC control and protection cabinet.
