Abstract
Considering the influence of surge current and voltage flickering on the distribution power system induced by medium frequency arc furnaces, the Hybrid Active Power Filter (HAPF) is applied to suppress the harmonics and compensate reactive power of 10kV bus of a steel mill. In order to study superiority effect and stability of HAPF, the Graph Theory is used to analyze its complex topology. By Graph Theory (GT) the HAPF can be described by several nodes that are connected by the power flows. Considering the important effect of LCL-filter of APF for suppressing harmonics such as high-frequency switch harmonic, its parameters are calculated by derived dynamic differential equations. Simulation and actual measure results show that the idea of combining the Graph Theory with dynamics modeling method is an effective path to design HAPF.
