This paper studies the most time-consuming sparse matrix fast solving problem in the electromagnetic transient simulation of a power system. It adopts the design idea of algorithm definition architecture, proposes a DAG static parallel scheduling algorithm, and designs a suitable hardware parallel to accelerate the array architecture. In the design and implementation, in order to solve the sparse matrix in the electromagnetic transient simulation operation, the precise beat-level hardware resource scheduling is adopted to realize the highly integrated software and hardware coordination acceleration. A design test and performance analysis is carried out. The results show that the structure and method performance is better than general-purpose CPU and GPU in the sparse matrix operation of a power system.
