Series RLC Load (Power System Blockset)

Implement a linear series RLC load

Library

Description

The Series RLC Load block implements a linear load as a series combination of RLC elements. Enter the value of the nominal voltage and nominal frequency in the first two entries. Enter the desired active power, the inductive reactive power and the capacitive reactive power in the last three entries. Only elements associated with nonzero powers will be displayed in the block icon. The inductive and capacitive reactive powers should be entered as positive values. At the specified frequency, the load will exhibit constant impedance and its power will be proportional to the square of the applied voltage.
