| 摘 要： | 基于金沙江一期向家坝—南汇±800 kV直流输电工程的具体参数，利用电磁暂态计算软件EMTP-RV，针对直流输电控制保护动作特性对内过电压的影响进行了详细的仿真计算和分析总结，并对高压直流输电内过电压的研究方法提出了可行性建议。研究结果表明，高压直流输电系统控制保护动作时序对内过电压影响较大，在研究高压直流输电系统的内过电压时，应尽可能模拟实际直流输电系统控制保护的动作时序，以确保仿真结果更加接近实际系统。

| Abstract: | Based on the concrete parameters of the ±800kV UHVDC transmission system from Xiangjiaba to Nanhui, the detailed calculation and analysis on the influence of HVDC control and protection characteristics on internal overvoltage are conducted by use of electromagnetic transient calculation software EMTP-RV. The feasible suggestions for the study on the inner overvoltage of HVDC transmission system are proposed. Research results show that HVDC control and protection characteristic evidently impacts the inner Overvoltage. The main characteristic, which should be simulated as closed as possible to that of the real projects, need considered fully. |
