Information

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 multiphase connector; a multiphase 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 the Modelica Specification dealing with Overconstrained Equation Operators for Connection Graphs have to be taken into account.
