The Supression Methods of DC Side Harmonic Current and Resonance Overvoltage Adorpted in Zhou-shan DC System
摘要
讨论了舟山HVDC系统调试中发生的极线2次电压谐振及回线6次电压谐振的原因
计算了DC侧谐波电流的发生及其分布
建议在线路两端加装DC滤波器抑制上述过电压
初步计算了6次滤波器参数及加装后的效果。
Abstract
The 2-nd poler line voltage resonances and the 6-th return line voltage resonances occured in Zhou-shan system test have been discussed. The origination and distribution of the DC side harmonic current have been calculated. The suggestions that the resonance overvoltage mentioned above can be suppressed by DC filters located at both terminations of DC line have been made. Preliminary estimation on the effects and parameters of 6-th harmonic filters has been done.
