Time vs. Phasor Domain Simulation
EMTDC is a class of simulation tool, which differs from phasor domain solution engines, such as load-flow and transient stability programs. These tools utilize steady-state equations to represent electrical circuits, but will actually solve the differential equations of machine mechanical dynamics.
EMTDC results are solved as instantaneous values in time, yet can be converted into phasor magnitudes and angles via built-in transducer and measurement functions in PSCAD - similar to the way real system measurements are performed.
Since load-flow and stability programs work with steady-state equations to represent the power system, they can output only fundamental frequency magnitude and phase information. EMTDC can duplicate the response of the power system at all frequencies, bounded only by the user-selected time step.
What is EMTDC?
EMTDC (which stands for Electromagnetic Transients including DC) represents and solves differential equations (for both electromagnetic and electromechanical systems) in the time domain. Solutions are calculated based on a fixed time step, and its program structure allows for the representation of control systems, either with or without electromagnetic or electromechanical systems present.
