HVDC terminals are modeled in load flow and stability programs using certain relationships for real and reactive power derived from a set of assumptions for fundamental frequency voltages and currents. A representation where network phenomena are treated in complete differential equation form with switching of thyristors on a cycle-by-cycle basis yields results which include harmonic effects. This paper compares digital simulation results obtained by both methods.
