摘要
220 kV公坪变由于给湘黔、渝怀2条电铁供电,是湖南省电网谐波污染最严重的变电站。湖南省电力公司试验研究院为该站设计了谐波治理装置,并对该装置进行了现场调谐试验和现场滤波效果验证性试验。试验结果:该变电站10 kV侧的VTHD由7.95%下降到3.21%,110 kV侧的VTHD由6.91%下降到2.89%,220 kV侧的VTHD由4.09%下降到2.70%,显示出良好的滤波效果,达到了预期目的。
Because of power supply for Xiangqian and Yuhuai electric railway, 220 kV Gongping substation is the most harmonic pollution substation in Hunan. A harmonic control device for the substation was designed and carried field tuner test and filtering effect verify test. The results showed that VTHD at 10 kV side fell from 7.95% down to 3.21%, VTHD at 110 kV side from 6.91% to 2.89%, and VTHD at 220 kV side from 4.09% to2.70%. The result indicated that the filtering effect is good and achieves expect goal.
