摘要
介绍了有源电力滤波器在低压配电网络中的应用,通过实时监测供电线路中变频器、变速传动装置、各种直流电源等设备产生的高次谐波,动态抑制高次谐波,消除谐波电流对供电网络中设备的危害,降低能源消耗,提高供电品质,保证供电设备及用电设备的安全运行。
The application of active power filter in low-voltage distribution network is discussed in this article.The ultraharmonics is dynamically suppressed by monitoring the ultraharmonics generated by frequency converters,variable-speed drive devices and all kind of DC sources in the charging lines.Because the harm of harmonic wave in the charging lines is lessened,electric energy is saved as well as the quality is improved.In the end,the safety operation of the power supply units and electric equipments is ensured.
