Operation
The information in the following sections affect the inverters only. Information on the operation of further optional
devices of the MV Power Station, such as the medium-voltage switchgear or the control device for cascade control,
can be found in the documentation of the respective device.
8.1
Safety during Operation
Danger to life due to arc fault caused by fault in the medium-voltage switchgear
If there is a fault in the medium-voltage switchgear, arc faults may occur during operation of the product which can
result in death or serious injuries. If arc faults occur in the medium-voltage switchgear, the pressure evacuates under
the compartment of the medium-voltage switchgear.
• Only perform work on the medium-voltage switchgear when it is in a voltage-free state.
• Only perform switching operations on the medium-voltage switchgear from the service platform.
• Do not touch or access the roof of the medium-voltage switchgear when medium voltage is connected.
• When switching operations are performed, all persons that are not on the service platform have to keep a safe
distance from the product.
• All work and switching operations on the medium-voltage switchgear must only be performed by qualified
persons wearing adequate personal protective equipment.
Operation failure of the PV power plant due to incorrectly set parameters
If the parameter settings for grid management services are incorrect, the PV power plant may not be able to meet the
requirements of the grid operator. This can involve yield losses and the inverter may have to be disconnected by the
grid operator.
• When setting the modes of grid management services, ensure that the control procedures agreed with the grid
operator are parameterized.
• If the inverter is operated with a Power Plant Controller, ensure that the mode
WCtlCom
for active power
limitation and the mode
VArCtlCom
for reactive power control are selected in the inverter.
