Abstract

This paper mainly researches automatically optimal decoupling technology for electromagnetic transient. After making clear advantages and disadvantages and selection principles of long transmission line decoupling algorithm and node-splitting algorithm, it analyzes the influence of computing time of different elements, decoupling borders, communication between subnets, IO calls on simulation time and parallel computing efficiency. It obtains formulas of subnet execution time for different parallel simulation algorithm. It analyzed automatically optimal decoupling algorithm for electromagnetic transient in real-time simulation step size constraint which is suitable for mixing-step simulation and develops the algorithm based on ADPSS. Finally, it verifies the correctness of the algorithm through practical grid and achieves real-time simulation of the grid.
