Principle of a grid-connected PV system with a Sunny Central

Object Description

APV Generator BSunny Central CPublic grid

Sunny Central

The Sunny Central is equipped with a low-voltage transformer, and feeds into the low-voltage grid.

Sunny Central HE

The Sunny Central HE does not have its own low-voltage transformer. It requires an adapted external medium-voltage transformer via which it can feed into the grid.

Sunny Central LV

The Sunny Central LV feeds into the low-voltage grid. It is suitable for the connection of PV generators with low voltage.

Sunny Central MV

The MV stations are medium-voltage stations. In an MV station, two Sunny Central HE devices feed into the medium-voltage grid via a shared medium-voltage transformer.

2.4 Operating Modes

After switch-on, the Sunny Central runs through the different modes illustrated below. When switched off, the Sunny Central is in the "Stop" mode. By turning the key switch, the Sunny Central goes into to the "Wait" mode.

12 SC-BEN100262 User Manual

SMA Solar Technology AG Safety

Operating mode Explanation

Stop The Sunny Central is switched off. The Sunny Central remains in this

condition until the key switch is turned to "Start".

Wait If the key switch is set to "Start", the Sunny Central goes into to the "Wait"

mode. The start voltage "VpvStart" must be adjusted to conform to the PV

generator connected to the Sunny Central. Check and adjust the start voltage as necessary.

If the input voltage is below the set start voltage "VpvStart", the Sunny Central remains in "Wait" mode. The value for "VpvStart" is shown in the display of Sunny Central Control.

If the input voltage is higher than the start voltage "VpvStart", the Sunny Central waits until the time defined in the parameter "TStart" has elapsed. If the input voltage has not fallen below the start voltage "VpvStart" during this p eriod, the Sunny Cen tral checks whether there is connection to the AC grid. If there is a valid AC grid connection, the AC contactor clos es and t he Sunny Central transfers to grid monitoring.

Grid Monitoring The grid is monitored for adherence to grid limits for the monitoring time

"GriGrdMonTm". If the grid limits are not exceeded during this time, the Sunny Central goes into the "Startup" mode.

Startup After completing grid monitoring, the Sunny Central navigates to its first

operating point and commences grid feed.

MPP load operation In MPP operation the Sunny Central feeds power to the grid and operates

continuously at the maximum power point (MPP).

Shutdown The Sunny Central shuts down (switches off) in the following cases:

• The power measured during the time interval "TStop" is less than "PpvStop".

• A failure has occurred which necessitates shutdown of the Sunny Central.

• The key switch is set to "Stop".

Failure If a fault occurs during operation, the Sunny Central shuts down and the

Sunny Central Control displays the fault. You will find a list of faults in section 15”Troubleshooting and Problem Solving” (page80).

Grid Security Management SMA Solar Technology AG

3 Grid Security Management

3.1 What are the requirements?

In Germany, PV systems with an installed capacity of more than 100 kWp must participate in feed and grid security management. First and foremost, the utility operator must be able to limit the power of the PV system by remote control, and temporarily reduce it to zero i n critical cases. Releva nt cont rol commands from the utility operator must therefore be transmitted quickly and reliably to the Sunny Central.

The requirements in detail

• Reception of the setpoint via a centralized ripple control signal receiver with 2 or 4 relays.

• Limitation of the feed-in power in 4 configurable stages (for example, 0 % / 30 % / 60 % / 100 % of the agreed installed active power P

• Setting of the required setpoint in less than a minute.

3.2 Active Power Limitation

Under certain circumstances, the grid operator is entitled to dictate a temporary limitation of feed-in power or to implement a system shutdown. According to the Medium-Voltage Directive, generator systems must be able to reduce their active power in stages of no more than 10 % of the agreed installed active power P the connected system power have become standard practice.

. However, the four staged reductions of 100 %, 60 %, 30 % and 0 % of

3.3 The Solution from SMA Solar Technology

With the Power Reducer Box it is possibl e to imp lement active power limitation in accordance with the requirements of grid security management (GSM) for a PV system.

To do this, four di gital stat es (e.g. of a radio ripple contro l receiver ) can be imported v ia the t he Pow er Reducer Box, thus enabling the Sunny Central to be set according to the specifications of the utility operator.

The four input ports are freely configurable via the integrated web interface. If a signal from the radio ripple control receiver is present, the Power Reducer Box analyzes the signal and relays an instruction via the Ethernet network to the registered Sunny WebBox devices.

Activated Sunny WebBox devices transfer the instruction to the connected Sunny Central. Events are recorded onto the internal memory of the Power Reducer Box. In addition, it is possible to

write events onto an SD card or download events via the web interface.

Besides the Power Reducer Box, there are two further options for meeting the requirement of grid security management. These are 1) reception of the signals via an analog input on the Sunny Central and 2) manual setting of default values via parameters.

How to implement these options is described in this manual.

4.2 Sunny Central

4.2.1 Indicator Lights

There are 2 indicator lights at the front of the Sunny Central. If an error occurs, these indicator lights indicate the type of failure.

Meaning of the colors

Yellow: The Sunny Central is in "Alert" status. The Sunny Central does not switch off. Check the

system. Once the error is no longer active, the fault indication is automatically reset.

Red: The Sunny Central is in "Fault" status. If the Sunny Central has detected a fault, it will shut

down. Once the error has been rectified and cleared, it will resume operation. For more information see Section 15.1.2”Types of Faults and Warnings” (page81).

4.2.2 Key switch

The key switch is used to switch the Sunny Central on and off. After turning the switch to the "Start" position, the Sunny Central switches from the "Stop" mode to the "Wait" mode. Given sufficient irradiation and a valid grid, the Sunny Central goes into grid feeding operation. If the irradiation, and thus the input voltage, are too low, the Sunny Central remains in "Wait" mode.

When the key switch is turned to "Stop", the DC main switch is automatically switched off by a motor drive.

4.2.3 AC Main Switch

NOTICE!

Improper use of the AC main switch may cause damage to the Sunny Central.

The components of the Sunny Central are subject to considerable stress if the AC main switch is actuated under load. Frequent use of the AC main switch can cause stress-related damage to individual components.

• Switch off the Sunny Central with the key switch.

• Operate the AC main switch.

The AC main switch enables you to disconnect the Sunny Central from the grid on the AC side.

4.2.4 Emergency Stop

NOTICE!

Improper use of the emergency shut-off switch may cause damage to the Sunny Central.

The components of the Sunny Central are subject to considerable stress if the emergency shut-off switch is actuated under load. Frequent use of the emergency shut-off switch can cause stress-related damage to individual components.

• Only use the emergency shut-off switch in an emergency.

• Switch off the Sunny Central with the key switch.

The emergency shut-off switch immediately disconnects the Sunny Central from the grid and the PV generator, thus putting the Sunny Central in a safe state.

By pressing the emergency shut-off switch, the device is locked in the "Off" position. The emergency shut-off switch can only be deactivated with the appropriate key. In addition, the activation of the emergency shut-off switch must be cleared using Sunny Central Control or Sunny Data Control.

You can install an external emergency shut-off switch on each Sunny Ce ntr al o r co nne ct s eve ral Sunny Centrals via a shared emergency shut-off switch.
