Item Description

Nominal plant AC power Enter the total nominal AC power for the entire plant. This value is necessary for

correct calculation of the absolute reactive power Q.

Q and PF settle time Enter the system settling time for reactive power regulation.

Range: 10 – 60 seconds.

Control type Specifies whether the control should be Open loop (enabled) or Off (disabled).

Reference value Select a reference for reactive power

• Grid management box

• Reactive power Q

• Power factor PF

• Set point curve PF(P)

• Set point curve Q(U)

Grid management box

• The grid management box receives set point values for reactive power and PLA from

the DNO. Configure the grid management box inputs under: Relay configuration. For

more information refer to the TripleLynx CN Reference Manual and the Grid Manage-

ment Box Manual.

Reactive power Q

• Enter the fixed set point value for the plant reactive power Q as either:

- percentage value of the nominal plant AC power (%)

Range: 0 – 60% of the nominal plant AC power, over-excited or under-exci-

ted.

- value of Q (kVAr)

Power Factor PF

Enter the fixed set point value for the plant power factor.

Range: 1 – 0.8 over-excited or under-excited.

Set point curve PF(P)

The power factor is defined as a function of the plant output power. Enter the values for the set

point curve under:

PF(P) Curve
