4.2.1.6 Actual Data & Status Panel
At the panel you can observe all of essential actual network quantities and state of power factor
control process.
The data are arranged in folders and you can list through them with the ▲and ▼buttons. Power
factor format can be selected using the
button ( described further below ).
4.2.1.6.1 Actual Data Folders
Particular folders contain following actual data :
•
Pfh
… fundamental harmonic active power
•
Qfh
… fundamental harmonic reactive power
•
ΔQfh
… control deviation – difference between fundamental harmonic reactive power and
target reactive power corresponding to preset target power factor
•
cos φ
/
tan φ
/
φ
... fundamental harmonic power factor in form of “cos”, “tan” or angle,
respectively
•
S
… apparent power
•
U
LL ,
