Abstract

Abstract:

The electromagnetic-electromechanical transient hybrid real-time simulation platform called super-mixed real-time simulation （SMRT） has wide application prospect in the analysis of large-scale AC/DC power grid because of its advantages in simulation scale, simulation accuracy and easy use. At present, SMRT has been applied in the simulation analysis and research on the electromechanical transient behavior and stability characteristics of the large-scale AC/DC power grid, the rapid repetition of failure/accident in actual power grid based on typical operation modes, the production operation service of AC/DC system such as major operation risk assessment, and the system performance and control strategy, the role and influence of power electronic device of dynamic compensation for grid on the commutation failure recovery of grid after multi-DC fault, as well as the teaching and training of the dispatcher. After further development, SMRT can be applied in the system-level relay protection setting and verification and other problems.

Key words: super-mixed real-time simulation（SMRT）, hybrid real-time simulation, AC/DC power grid
