Converter electromagnetic transient simulation parallel optimization method and device and storage medium

The invention discloses a converter electromagnetic transient simulation parallel optimization method, converter electromagnetic transient simulation parallel optimization equipment and a storage medium, belongs to the technical field of electromagnetic transient simulation of a power system, and remarkably reduces unnecessary intermediate variables and shortens a simulation calculation process through combination. The multiplication operation of the matrixes C and D and the matrixes Un and k and the multiplication operation of the matrixes A and B and the Itotal are performed at the same time, and the calculation process between rows is independent, so that the parallel degree of electromagnetic transient simulation calculation is increased; because the parameter matrix does not change along with the change of the switch state, the parameter matrix is pre-calculated and stored in the simulation initialization stage, and only the time of register reading operation needs to be consumed in the calculation of a
