Fundamental Power Factor, Total
Fundamental power factor indicates the relationship between useful power (Watts and
fundamental VARs. The block calculates fundamental power factor approximately twice
per second, based upon the relative magnitude of active power and fundamental VARs.
PFfun = COS Θ fun =
W
( W2 + VARfun2 )
The sign of the fundamental power factor indicates the direction of power flow. If the
sign is positive, power is being delivered to the load. If the sign is negative, power is
being fed back into the system.
