Buildings.Electrical.AC.OnePhase.Examples.GeneratorLoadGrid

Generator with a load and grid connection

Buildings.Electrical.AC.OnePhase.Examples.GeneratorLoadGrid

Information

This model illustrates a generator, an inductive load and a grid connection. The power output of the generator is equal to its input signal, which is a ramp function. The output grid.P shows the actual and apparent power, the power factor and the phase angle.

Buildings.Electrical.AC.OnePhase.Examples.GridDCLoad

Model of a DC load connected to the grid

Buildings.Electrical.AC.OnePhase.Examples.GridDCLoad

Information

This model illustrates the use of a model for inductive load. The circuit on the left hand side uses an inductive load, whereas the circuit on the right hand side uses a resistor and inductance in series. The parameters of the inductor and resistor are such that the real power and the phase angle are identical (up to the numerical precision of the parameters) for the two systems.
