Design tools of DC EAF power supply systems for optimum reduction of flicker and interharmonic disturbances

摘要

Ansaldo utilizes simulation and analytical tools for analysis and system design to prevent harmonic interaction and to optimize the design of the entire power supply system in terms of cost,losses and performance.The results and measurements taken in a DC EAF installation in the U.S. show that the whole system,through adopted provisions,is able to match the desired specification in terms of flicker,harmonics,interharmonics,voltage unbalances and power factor.
