Three phase series RLC load block

Hi,

When I use the "3 phase series RLC load" block how exactly does it work?

For the parameters of the figure for example, does it absorbe 100 VARs of reactive power when there is positive reactive power in the circuit and -100 VARs of reactive power when there is negative reactive power in the circuit?

Thanks in advance,

The Three-Phase Series RLC Load block implements a three-phase balanced load as a series 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.

The reactive power (in VARs) depends on the inductive and capacitive components of the load:

• Inductive Load: Consumes reactive power (positive VARs).
• Capacitive Load: Supplies reactive power (negative VARs).

hen you specify the reactive power (e.g., 100 VARs), it indicates the amount of reactive power the load will consume or supply.
