Var/PF Control

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

The var/PF function controls the power factor on all of the DSLC-2 equipped machines operating in

isochronous load sharing. The PF control begins on breaker closure. The MSLC-2 has three modes of

Var/PF control (which are selected in Menu 4):

• Constant generator power factor – sets the power factor reference on all of the DSLC-2 con

trols to the internal reference chosen in the MSLC-2. The power factor can then be adjusted

using the voltage raise and lower inputs. The voltage raise command will make the power fac

tor more lagging. Conversely, the voltage lower command will make the power factor more leading.

• Utility tie power factor control – adjusts the power factor reference on all of the DSLC-2 con

trols in isochronous load sharing in order to maintain the power factor across the utility tie.

• Utility tie var control – adjusts the power factor reference on all of the DSLC-2 controls in

isochronous load sharing in order to maintain the level of vars being imported or exported from the utility.

The var/PF control mode begins with the load control mode selected. The constant generator power

factor and the utility tie power factor control can have the reference setting controlled by an analog in

put (see Menu 6). By closing the voltage raise and lower discrete inputs, you can select the analog re

mote input for reference control.
