Technical field [0001] The invention relates to a hybrid simulation interface management module based on PSCADEMTDC (power system computer-aided design electromagnetic transient simulation program), which belongs to the technical field of power system digital simulation. Background technique [0002] In modern power systems, high-voltage direct current transmission systems and flexible direct current transmission equipment have been widely used. The overall scale of the power grid is large, the regional connection is close, and the electromagnetic transient process and the electromechanical transient process are closely coupled. Traditional electromagnetic transient simulation has a fine description of the electromagnetic transient process, but the simulation step is small, the electrical component model is complex, and the amount of calculation is large. It is difficult to directly apply to the study of large-scale power grids. It needs to be equivalent and simplified by the netw...

Problems solved by technology

Existing software is still based on a simulation idea and model in electromagnetic transient simulation or electromechanical transient simulation, and fails to realize the direct interface between the two. The fine simulation of the electromagnetic transient process of the system and power electronic equipment requires the interface management system of the simulation platform on both sides to effectively select and organize the interface quantity, and meet the data requirements of the simulation on both sides at the minimum cost
