| 摘要: |
| 运用VSC-HVDC对多直流馈入系统进行分区能够提升受端系统的运行性能。不同分区方案对系统性能提升程度不同。为了寻找最优方案，运用灵敏度分析法对多直流馈入系统的特性进行了研究，得到了制定分区方案的两个基本原则。在此基础上提出了基于多馈入交互作用因子的直流分区方法，进而得到受端系统分区的最优方案。以广东电网2030水平年作为案例，运用该分区方法对广东电网进行分区，得到了最优分区方案。运用PSS/E 进行仿真，验证了该最优分区方案的有效性。该方案对于实际工程中分区方案的制定具有指导意义。 |

| Abstract: |
| The operating performance of receiving terminal power system can be improved by segmenting a multi-infeed HVDC system into a set of asynchronously operated DC-interconnected sectors using VSC-HVDC. Different DC-segmentation schemes have different impact on multi-infeed system. In order to figure out the optimal scheme, this paper firstly analyzes the characteristics of multi-infeed systems by sensitivity method and puts forward two principles of DC-segmentation. Secondly according to these principles, a DC-segmentation method based on multi-infeed interaction factor is presented and then the optimal scheme of receiving terminal power system partition is got. Finally, by applying the method, an actual large scale network is studied and the optimal DC-segmentation scheme is obtained. The effectiveness of the optimal scheme and the DC-segmentation method is verified through simulations on PSS/E. This paper has guiding significance for making DC-segmentation schemes in real projects. |
