摘要：
Installing active power filters (sometimes called active harmonic filters or line conditioners) in an electric power network can improve the quality of electricity supply. A shunt active power filter, with a current-source PWM inverter and a conventional copper inductor as its energy storage, has a significant power loss. The power loss in this copper inductor can be substantially reduced by replacing the inductor with a high-temperature superconducting (HTS) magnet. Several solenoid design alternatives using silver-sheathed BSCCO-2223 tape have been made for the HTS magnet that has an inductance of 0.5 H for this application. A liquid-nitrogen-cooled HTS magnet has been built and tested for use in an active power filter. The loss-reduction effect of using the HTS magnet with the current-source active power filter has been investigated experimentally, and the results are compared with those when using a conventional copper inductor. Practical issues such as air-core design versus iron-core design and using liquid-nitrogen cooling or a cryocooling are analyzed and discussed.
