摘要
在我国通信网络的综合屏蔽能力较以前有了大幅度提高的情况下,研究了取消直流滤波器对±800 kV直流输电系统谐波水平的影响。以已经投运的向家坝—上海和锦屏—苏南±800 kV特高压直流输电工程为例,重点研究了取消直流滤波器对±800 kV特高压直流输电系统等效干扰电流、直流侧谐振以及换流站设备中谐波水平的影响。研究结果对后续的±800 kV特高压直流输电工程直流滤波器设计具有一定的参考作用。
Under the circumstance of great improvement of the comprehensive shield ability of communication network in China than ever before, the influence of cancelling DC filter（DC filter, DCF in short）on harmonic level of ±800 kV HVDC system harmonic level is studied. In this paper, Xiangjiaba-shanghai and Jinping-sunan ±800 kV UHVDC transmission project which has been in operation is taken as an example, the influence of cancelling DC filter on equivalent interference current, resonance a DC side and harmonic level in the equipment of converter station of the ±800 kV UHVDC system is studied. The study result has a definite reference to the DC filter of subsequent ±800 kV UHVDC transmission projects.
