5.7.1. System Parameters

In Fig. 5.7.1.a the system parameters configuration area is shown.
Generator Electrical Data

Rated Voltage (V): enter in this field the generator rated voltage value (phase-phase).

Rated Current (A): enter in this field the generator rated current value.

Rated Power Factor: enter in this field the generator rated power factor value.

Rated Frequency (Hz): enter in this field the generator rated frequency value.

Rated Excitation Cirrent (A): enter in this field the generator rated excitation current value.

Rated Real Power (kW): based on the data entered in the previous fields, the MEC-100 Interface System calculates the
generator rated real power value.

Rated Reactive Power (kvar): based on the data entered in the previous fields, the MEC-100 Interface System calculates
the generator rated reactive power value.

Rated Apparent Power (kVA): based on the data entered in the previous fields, the MEC-100 Interface System calculates
the generator rated apparent power value.
System Options

Voltage Sensing: in this field the user can define the type of sensing required by a given application: single-phase or three-
phase sensing.

PF/VAR: network parallel mode selection field; in this field you can select which regulation mode should be used in the
network parallel operations. When the PF/VAR contact (see Par. 3.5.6) is closed, the MEC-100 will perform the adjustment
of the power factor if PF has been selected or the reactive power if VAR has been selected.
Aux. Analog Input Setting

No: if this option is selected, no analogue auxiliary input will be associated to the generator voltage setpoint.

1° In.: if this option is selected, analogue auxiliary input 1° will be associated to the generator voltage setpoint.

2° In.: if this option is selected, analogue auxiliary input 2° will be associated to the generator voltage setpoint.
Aux. Analog Input Setting

No: if this option is selected, no analogue auxiliary input will be associated to the power factor or reactive power setpoint (it
depends on the Operating Mode selected in System Parameter area, see Par. 5.7.1).

1° In.: if this option is selected, the analogue auxiliary input 1° will be associated to the power factor or reactive power
setpoint (it depends on the Operating Mode selected in System Parameter area, see Par. 5.7.1).

2° In.: if this option is selected, the analogue auxiliary input 2° will be associated to the power factor or reactive power
setpoint (it depends on the Operating Mode selected in System Parameter area, see Par. 5.7.1).
