【摘要】 从直流滤波器性能的角度分析了影响云广±800kV直流输电工程等效干扰电流的因素,包括换流器对地杂散电容、平抗布置方式、直流滤波器型式等因素对直流滤波器性能的影响。然后参照目前直流输电工程的发展趋势,提出云广±800kVUHVDC输电工程合理的直流谐波指标。
【Abstract】 The factors influencing the equivalent disturbing current of Yun-Guang ±800 kV UHVDC transmission system are analyzed from the point of view of DC filter performance that can be affected by the stray capacitance of converter, the layout of smoothing reactors and the type of DC filters. Then refering to the development trend of DC transmission projects, the reasonable DC harmonic criteria for Yun-Guang ±800 kV UHVDC project is proposed.
