EFFICIENT DYNAMIC SYNCHRONOUS MACHINE SIMULATION WITH HARMONICS

Within this paper, an efficient procedure for the dynamic simulation o f faulted synchronous machines operating in the presence of harmonics is presented The algorithm employs steady-state frequency domain techn iques for simulation of the transmission system sequence networks and time domain methods for the synchronous machiner represented in the od q frame of reference. The procedure affords greater accuracy then conv entional fault analysis techniques based strictly on steady-state meth ods, yet requires far less computational time than full system dynamic simulations such as those using the EMTP.
