| 摘 要： | 为有效提升对覆冰输电线路的模拟效果，设计了自然环境灾害下配网覆冰输电线路模拟系统。对覆冰灾害进行了理论分析，以实际的配网线路工程为原型，对交流系统、换流阀、换流变压器以及直流电缆进行等效模拟。在所设计的配网覆冰输电线路模拟系统中，不仅采用了与实际工程现场中相同的测量系统，还完成了覆冰后故障模拟并实现对应故障点的设置。设计了模拟系统的稳态等相关实验，将其与实际工程进行对比，通过仿真结果全面验证了该系统的有效性以及优越性，能够为在覆冰状态下维护配网稳定性提供有效支持。

| Abstract: | In order to effectively improve the simulation effect of iced-covered transmission lines，a simulation system for iced-covered transmission lines of distribution network under natural environmental disasters was designed.Firstly，the theoretical analysis of icing hazard was carried out，and then the equivalent simulation of AC system，converter valve，converter transformer and DC cable was carried out with the actual distribution network line engineering as the prototype.In the simulation system of distribution network ice-covered transmission line，the same measuring system was used as in the actual engineering field，and the fault simulation after icing is completed and the corresponding fault point was set up.Finally，the steady-state experiments of the simulation system were designed and compared with the actual engineering.The effectiveness and advantages of the system were fully verified by the simulation results，which can provide effective support for maintaining the stability of the distribution network under the condition of icing. |
