摘要

文中分析了±1 100 kV特高压直流输电工程换流器在直流侧产生的谐波的特点

根据现有的工程参数计算出了换流器在直流侧产生的谐波电压

并将计算结果与±800 kV高压直流输电工程做了比较。文中以规划的±1 100 kV特高压直流输电工程为例

对换流器在直流极线和地极引线上产生的等效干扰电流进行了计算。通过对多种直流滤波器配置方案的滤波性能进行试算

最终给出了推荐的直流滤波器配置方案

该方案满足滤波性能限制要求并且造价较低。文中同时计算出了该配置方案下直流极线和地极引线上的最大等效干扰电流:双极2 728 mA

单极5 882 mA。文中的研究结果对最终确定实际工程直流滤波器方案具有一定的参考作用。

Abstract

The characteristic of the DC side harmonics produced by the converter in ±1 100 kV HVDC project is analyzed in this article.The DC side harmonic voltage is calculated according to the available project parameters.The calculation result and ±800 kV HVDC project are compared.The equivalent disturbing currents in DC pole lines and DC electrode lines are calculated.After many times filtering performance result for different DC filter schemes are calculated

finally one DC filter solution

which satisfies the performance limits and low-cost

is proposed.The maximum equivalent disturbing currents in DC pole lines and DC electrode lines is calculated.The maximum equivalent disturbing current: bipolar mode 2 728 mA;unipolar mode 5 882 mA.The result of this study is helpful in determining the final project DC filter solution.
