Implement linear series RLC load
The Series RLC Load block implements a linear load as a series combination of R L C elements. At the specified frequency, the load exhibits a constant impedance. The active and reactive powers absorbed by the load are proportional to the square of the applied voltage. Only elements associated with nonzero powers are displayed in the block icon.
The nominal voltage of the load, in volts RMS.
The nominal frequency, in hertz.
The active power of the load, in watts.
The inductive reactive power QL, in vars. Specify a positive value, or 0.
The capacitive reactive power QC, in vars. Specify a positive value, or 0.
If selected, the initial capacitor voltage is defined by the Capacitor initial voltage parameter. If not selected, the software calculates the initial capacitor voltage in order to start the simulation in steady-state.
The Set the initial capacitor voltage parameter have no effect on the block if the capacitive reactive power is equal to zero.
The initial capacitor voltage used at the start of the simulation. The Capacitor initial voltage parameter have no effect on the block if the capacitive reactive power is equal to zero and if the Set the initial capacitor voltage parameter is not selected.
If selected, the initial inductor current is defined by the Inductor initial current parameter. If not selected, the software calculates the initial inductor current in order to start the simulation steady-state.
The Set the initial inductor current parameter have no effect on the block if the inductive reactive power is equal to zero.
The initial inductor current used at the start of the simulation. The Inductor initial current parameter have no effect on the block if the inductive reactive power is equal to zero and if the Set the initial inductor current parameter is not selected.
Select Branch voltage to measure the voltage across the Series RLC Load block terminals.
Select Branch current to measure the current flowing through the Series RLC Load block.
Select Branch voltage and current to measure the voltage and the current of the Series RLC Load block.
Place a Multimeter block in your model to display the selected measurements during the simulation. In the Available Measurements list box of the Multimeter block, the measurement is identified by a label followed by the block name:
Measurement | Label |
---|---|
Branch voltage | Ub: |
Branch current | Ib: |
