±1100kV直流输电工程直流滤波器方案研究

Gaoya dianqi, 2013
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

高压端换流阀顶端接地故障引起的换流站直流场操作过电压仿真研究

Gaoya dianqi, 2014
依据向家坝—上海特高压直流输电示范工程实际设备参数建立了仿真分析模型,研究了换流站高压端换流阀顶端接地故障引起操作过电压的机理及分布规律,并分析了增加E1H型避雷器并联柱数和提高中性母线绝缘水平两种方案对过电压的抑制效果,对后续特高压直流输电工程避雷器优化配置有一定的指导意义。
