In power system simulation (by means of TNA or digital computer) equivalent networks can be used to reduce the simulation complexity. This paper presents an iterative pole-removal method based on the least-squares fitting techniq% to synthesize RLC equivalent networks according7 to their specified driving-point function in the frequency domain. The synthesized networks are composed of only passive components to represent the DC constant, complex poles as well as poles at zero and infinite. Poles are removed individually from the specified driving-point function applying the least-squares fitting with respect to the frequency domain around the relevant resonance. This algorithm converges quickly even for highly resistive systems.
