3 Configuring Integrated Plant Control
In order to operate PV systems with Integrated Plant Control, the following settings are necessary:
1. The individual design of the PV system with all of its essential equipment must be entered so that each inverter can
calculate its individual influence on the grid-connection point.
2. The desired characteristic at the grid-connection point must be set (generally specified by the grid operator).
3.1 Determining the Key Values of the System
In order to determine the parameter settings at the inverter, the equipment between the inverter terminals and the
grid-connection point must be characterized. Determine the following key values:
Cables Used
• Conductor material
• Cross section
• Cable length
MV Transformer
• Nominal apparent power (S
• Impedance voltage (v
• Impedance loss in case of short-circuit at nominal power (P
MV transformer data
You can usually find the required data on the MV transformer on the type label or datasheet. If these are not
available, contact the manufacturer.
3.2 Entering Key Values in Sunny Design
You can find a detailed manual for Sunny Design at www.SMA-Solar.com. Proceed as follows to enter the key values in
Sunny Design:
1. Open Sunny Design and log in as a user.
2. Create a new project.
3. Enter the project data.
4. Under Project data, select the option Carry out optimized reactive power adjustment with
Integrated Plant Control.
5. Select the button [Configure the PV system].
6. Select the PV arrays and inverters used from the menu.
7. Select the button [Wire Sizing].
8. If a project sub-distribution (LV3) is available, select the option Project subdistribution available (LV3) from the
Overview window.
9. In the Overview window, select the option Medium-voltage line and MV transformer available (MV).
