modelInductiveLoad
Partial model of an inductive load
Extends from Load.
Information
This is a model of a generic inductive load. This model is an extension of the base load model BuildingSystems.Electrical.Interfaces.Load.
This model assumes a fixed power factor pf when the flag use_pf_in = false
otherwise it uses the power factor specified by the input pf_in.
The power factor (either the input or the parameter) is used to compute the reactive power
Q given the active power P
Q = P tan(arccos(pf))
