Abstract:

With the formation of large-scale nationwide AC-DC interconnected power system in China, the dynamic characteristics of power system are increasingly complicated. Unified Dynamic Simulation is an important tool to analyze the dynamic characteristic, serious faults scenario and stability measures for this non-linear super large-scale power system, in which the electromagnetic transient, electro-mechanical transient, medium-term and long-term dynamic phenomena of power system are united for calculation. The present study and application status, current technical problems and prospects of Unified Dynamic Simulation technology were described, which mainly included the numerical integration method and modeling technologies involved in electromagnetic transient, electro-mechanical transient, medium and long-term simulation. It is pointed out that some key technologies, such as new numerical integration methods, DC transmission modeling method for multi-time scale simulation, parallel simulation software development with opening, interactive and intelligent methods, etc., are powerful simulation tools for the safe, stable and economical operation of large AC-DC power systems and the application researches of new technologies and new devices.

Key words: unified dynamic, numerical integration method, modeling technologies, parallel computing
