The reference angle gamma:
- defines the angular frequency
omega of the
voltages and currents of a circuit by means of omega =
der(gamma).
- is not a global quantity since it propagated through the
connector. Therefore, independent circuits of different frequencies
can be modeled in one model.
- is present only once in a polyphase connector; a polyphase
component has only one reference angle common to all phases.
- can be either constant or variable, but it has to be consistent
in one contiguous circuit.
- is defined by the sources.
Designing new components, the guidelines of
Section 9.4.1 (Overconstrained Equation Operators for Connection
Graphs) of the Modelica 3.4 specification have to be taken into
account.
