Controlled load#

block — Block appearance in REPEAT VISION#

The Controlled load unit implements a mathematical model of static load, which is an electrical load, in calculations represented by a constant shunt resistance (which is a branch with series active and inductive reactive resistances), which value is calculated by the following formula (1) :

(1)#\[Z=R+j\cdot X= \frac{U_{ном}^2}{S_{ном}}\cdot cos \phi_{ном}+j\cdot \frac{U_{ном}^2}{S_{ном}}\cdot sin \phi_{ном}= \frac{U_{ном}^2 \cdot P_{ном}}{S_{ном}^2}+ j \cdot \frac{U_{ном}^2 \cdot Q_{ном}}{S_{ном}^2}\]

where:

U\(_{rat}\) - rated load voltage, [V];

P\(_{rat}\) - rated active power consumed by the load, [MW];

Q\(_{rat}\) - rated reactive power consumed by the load, [MVAr].

Parameters of rated active and reactive powers are set using Automation blocks.
