| 摘要: |
| 针对数字-实物混合型变电站培训仿真一次系统的数字仿真计算，采用异步替代法在仿真步长内将多节点的一次系统仿真计算分割为节点较少且相互独立的部分网络模型计算，使其适用于并行计算，从而保证一次系统仿真的实时性。在分析异步替代法稳定条件的基础上，提出了一种改善稳定条件和提高计算精度的 π型重叠电路模型。通过对真实系统的仿真计算表明，π型重叠电路有效，在满足异步替代法稳定条件下仿真计算稳定，具有良好的收敛效果。 |

| Abstract: |
| The asynchronous substitution is applied in the digital simulation of primary system for the hybrid substation training and simulation system，which divides the multi-node simulative calculation into the independent subnet calculations for fewer nodes in one simulation step，suitable for parallel calculation to insure the real-time performance. The stability conditions of asynchronous substitution are analyzed and the π overlap model is applied to improve the stability condition and calculation accuracy，which is verified by the simulation for a real substation. The simulative calculation is stable and convergent when the stability conditions are satisfied. |
