研究基于传输线的并行全隐式多速率电磁暂态仿真算法。建立全隐式多速率电磁暂态仿真的基本理论模型，并结合传输线方程，建立了并行化多速率电磁暂态仿真算法。此算法并行化程度高于现有全隐式多速率算法，计算效率得到提升。同时提出了保证基于传输线的并行多速率算法稳定性的网络判据，并通过数学理论证明了判据的有效性。仿真研究表明，基于传输线的并行全隐式多速率电磁暂态仿真可能不稳定，采用了文中提出的稳定判据对分网进行调整后，仿真稳定。

This paper studies the parallel implicit multi-rate simulation algorithm,builds the basic modeling of this algorithm, and then,the parallel algorithm via the transmission line equation.The result shows that the multi-rate electromagnetic transient simulation algorithm based on transmission lines has higher parallelized levels and efficiency than the existing one. Meanwhile,a criterion for ensuring the stability of the multi-rate electromagnetic transient simulation algorithm based on transmission lines is proposed and proved by theory. Simulation study shows that the parallel implicit multi-rate electromagnetic transient simulation based on the transmission lines might be unstable,but after adjustment of the network division using the stability criterion proposed,the simulation becomes stable.
