Summary:Power systems may be simulated in the time domain or in the frequency domain. The most efficient simulation methods are the harmonic balance (HB) analysis of ADS and the periodic steady state (PSS HB) implemented in Cadence. Recently new frequency domain (FD) models of nonlinear loads have been proposed and implemented in ADS. Their performance has been compared only with transient analysis using time domain (TD) models of ADS. This paper compares the CPU times employing TD and FD models, using the following analyses: transient analysis and HB analysis of ADS, and PSS analysis (TD shooting) and PSS HB of Cadence. Using a test circuit with 100 rectifiers, the ADS HB with FD models proves to be much more efficient than the other methods.
