The strong magnetic fields generated by reactors, which not only interfere other electric equipmentspsila regularly running, but also are potentially harmful to substation employeespsila health, are the main electromagnetic contamination in substations. In this paper, a mixed finite-element (FE) model for dry-type air-core reactor, which considers the(More)
Active Power Filter (APF) is usually used to compensate the harmonic currents which are generated by the nonlinear load, and its compensation performance mainly depends on the estimation of APF mathematic model, instruction signal of harmonic currents and design of controller. Traditional control APF uses the average mathematic model, and PI controller and(More)
