Figure 3 : System overview of a large-scale PV power plant with 2 Power Plant Managers and 1 Redundancy Connector (example)
This system overview shows an example of the setup of a large-scale PV power plant with 2 Power Plant Managers
with Redundancy Connector. The joint operation of both the Power Plant Managers including the role change in case
of a fault works the same as with a large-scale PV power plant with 2 Power Plant Managers (see operating manual of
the Power Plant Manager).
For the use of digital inputs and outputs, such as with a medium-voltage switchgear, the Redundancy Connector is
recommended. The Redundancy Connector ensures a complete decoupling of the digital inputs and outputs. With this
decoupling, an active Power Plant Manager that keeps a digital output closed, can be replaced by the redundant
Power Plant Manager. After this replacement, the now active Power Plant Manager can open and close this output
regardless of the previous switch status. The system continues to operate securely by using the active system controller
(fail-safe operation) just as with a large-scale PV power plant with 2 Power Plant Managers. Only the active
Power Plant Manager controls the Redundancy Connector.
