摘要：
With the increment of scale of power system, in order to satisfy the requirements of power system electromagnetic transient simulation for calculation efficiency and accuracy, this paper proposed a transmission network fine-grained parallel electromagnetic transient simulation method based on block latency insertion method (Block-LIM). The algorithm fully considered the characteristics of the coupling components in the transmission network. The global fine-grained parallel processing was used for the update operations of node voltages and branch currents, so that the time complexity of the single-step loop of voltage and current update was reduced to a constant level. Thus, the simulation speed can be greatly improved from the algorithm level. Considering its fine-grained parallelism, the algorithm was implemented on GPU. This paper verified the algorithm's accuracy by comparing the simulation results with PSCAD on IEEE standard calculation cases, and it also improved the simulation efficiency compared to the node analysis method (NAM) in the simulation of large-scale systems. © 2022 Chin.
