System and autonomous frequency
Information
Example of two frequency-independent parts, one with system- and one with autonomous frequency.
The input 'omega_in' of voltage2 is connected to a signal source and the parameter fType is set to "Signal". The source delivers an angular frequency omega which is independent of the actual system frequency.
Note: the 'dynType'-parameter in 'system' only influences AC3ph components.
See for example:
meter1 v and i-signal, system frequency (60 Hz) meter2 v and i-signal, variable frequency (10 to 50 Hz)
