Illustration 10.2: Medium-Voltage Primary Frequency Control
The increase in output power follows a time ramp T (time gradient). The frequency-power gra-
dient S and the time ramp T are adjustable.
The frequency limit values f1 and f2 (activation and deactivation frequencies) differ internation-
ally.
For local values of f1 and f2, go to the download area at www.danfoss.com/solar, Approvals
and Certifications.

Reactive Power
The TLX CN+ and TLX CN Pro+ inverters are equipped with ancillary service features enabling
them to provide controlled reactive power and other support functions to the grid.
For information on reactive power in general, refer to the section
Reactive Power Theory
.
Note:
When using a third-party product, the factory settings (default setting OFF) must be applied.
For further details see section on
Managing Reactive Power Using
TLX CN+.
10.4.1. Reactive Power Mode
The settings for managing reactive power differ for TLX CN+ and TLX CN Pro+.
To select the mode of operation for reactive power,
for TLX CN Pro+:
- use the web interface
- refer to the section
Managing Reactive Power Using
TLX CN Pro+
for TLX CN+:
-
use the display. Navigate to the menu [Setup Reactive Power]
- when using a third-party product, the factory settings (default setting OFF)
must be applied
- refer to the section
Managing Reactive Power Using
TLX CN+
The inverter controls the reactive power setting in one of three modes, defined by 'setpoint
type':
OFF (default setting)
