Implement linear parallel RLC load

Fundamental Blocks/Elements

The Parallel RLC Load block implements a linear load as a parallel combination of RLC 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.

**Nominal voltage Vn**The nominal voltage of the load, in volts RMS (Vrms).

**Nominal frequency fn**The nominal frequency, in hertz (Hz).

**Active power P**The active power of the load, in watts.

**Inductive reactive power QL**The inductive reactive power QL, in vars. Specify a positive value, or 0.

**Capacitive reactive power QC**The capacitive reactive power QC, in vars. Specify a positive value, or 0.
