摘　　要：多馈入交互作用因子被用来描述多馈入系统中各直流系统间的相互作用程度。目前,多馈入交互作用因子计算方法主要有4类,分别是时域仿真法、阻抗法、灵敏度法及考虑直流外特性的阻抗法。本文首先对多馈入交互作用因子及其计算方法进行较深入地分析,特别对阻抗法进行了完善。然后以1个两馈入系统和1个36节点交直流系统为测试平台,对4类方法的计算结果进行比较和评估,分析4类计算方法的优势、不足及适应性。在此基础上,为电力系统不同的应用场景推荐合适的方法。The multi-infeed interaction factor(MIIF)is used to describe the degree of interaction between DC links in the multi-infeed system.At present,the calculation methods for MIIF are mainly divided into four categories,namely,the time-domain method,the impedance method,the sensitivity method and the impedance method considering DC external characteristics.This article first conducts a more in-depth analysis on the definition and computing methods of MIIF.In particular,the impedance method is improved.Then taking a double-infeed power system and a 36-bus AC/DC system as the test platforms,the calculation results of the four types of methods are compared and evaluated to clarify their advantages,shortcomings and applicability.Based on these,suitable methods for different application scenarios in power systems are proposed.
