| 摘要: |
| 为了定量考虑多直流系统中各直流系统之间的相互影响，提出一种更切合实际的基于潮流雅克比矩阵的多馈入相互作用因子(Multi-infeed Interaction Factor)解析表达式。目前相互作用因子主要通过仿真方法进行求解，其物理意义不明确。为此，从系统潮流出发，考虑交直流系统的共同影响，提出一种新的MIIF解析表达式，并验证了该方法的有效性。最后，比较分析了现有的三种基于电路原理的MIIF解析表达式和文中所提的解析表达式，从工程实用的角度给出了更具可行性的MIIF的计算建议。 |

| Abstract: |
| In multi-infeed HVDC system, because the electrical distances among DC converter stations are relatively short, the interactions and mutual influences between DC systems or DC system and AC system are complex. Multi-infeed interaction factor (MIIF) can effectively reflect the interactions and mutual influences. MIIF currently is mainly solved by simulation method which physical meaning is not clear. Therefore, a more realistic Jacobian matrix analytic expression is proposed. The simulation results have verified its effectiveness. At last, three MIIF analytic expressions based on circuit theory and the proposed Jacobian matrix analytic expression are compared with the simulation method, and some feasible suggestions from the practical engineering perspective are offered. |
