| 摘要: |
| 提出了基于希尔伯特变换的移频建模方法，并建立了基于模块化多电平换流器的多端柔性直流输电(MMC-MTDC)系统的电磁-机电暂态移频相量模型，进一步地在实时仿真器上实现了电磁-机电暂态分区并行计算。相较于传统电磁-机电暂态联合仿真方法，该建模方法与仿真平台的电磁-机电暂态仿真适用性强，接口简单实用。分别建立了模块化多电平换流器单端系统、±200 kV五端柔性直流输电系统接入IEEE 39节点交流系统的移频相量模型，并且完成了电磁-机电暂态分区并行实时仿真测试。通过对多种暂态现象的模拟及其与电磁暂态模型结果的对比，验证了所提电磁-机电暂态移频相量建模与实时仿真的准确性、有效性和灵活性。 |

| Abstract: |
| The SF(Shifted-Frequency) modeling method based on Hilbert transform is proposed, and an electromagnetic-electromechanical transient SF model of MMC-MTDC(Multi-Terminal Direct Current based on Modular Multilevel Converter) system is established. The electromagnetic-electromechanical transient simulation based on multi-area parallel computation is further implemented on a real-time simulator. Compared with traditional electromagnetic-electromechanical transient simulation approaches, the proposed modeling approach combined with the simulation platform has stronger applicability, simple and practical interface. The SF models of the single-terminal MMC system and the ±200 kV five-terminal MMC-MTDC connected to the IEEE 39-bus system are established. Based on this, the real-time electromagnetic-electromechanical transient simulation is complemented. Through the simulation of various transient phenomena and its comparison with the results obtained from electromagnetic transient models, the accuracy, effectiveness and flexibility of the proposed electromagnetic-electromechanical transient SF models and real-time simulation are verified. |
