Abstract
Analog computation has some inherent benefits over traditional digital computation methods and fosters a continued interest in research, specifically in power systems, due to its associated strengths. Among these advantages are physically realizable solutions, much faster computation times and more accurate models. To realize an analog computation environment for power system analysis analog models and their circuit realizations are required. This paper focuses on the design, simulation and hardware verification of transmission line models with variable parameters for the purpose of analog power flow computation. Specifically, pi equivalent lumped parameter and distributed parameter transmission line models with parametric variation based on temperature and frequency are presented. Operational transconductance amplifiers (OTAs) are the primary circuit elements in the hardware designs and allow remote reconfigurability and variation of transmission line parameters via transconductance gain. Test results are presented from a hardware prototype, which was developed and tested based on the proposed analog line models. Copyright (C) 2008 John Wiley & Sons, Ltd.
