Power Limitation Messages - ABB REACT 2 Series Product Manual

P
ower limitation messages
The following table gives the complete list of power limitation messages relating to string
inverters.
Some messages may not be used depending on the inverter model installed.
- Web server message
Name of Derating and Cause
- Warning
Power limitation:
The message indicates that the user has set an output power
limitation for the inverter.
- LIMxxx% CODE:00 LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
Power limitation due to over-frequency:
The message indicates that the user has set a power limitation
due to over frequency in order to reduce the maximum output
power of the inverter when the grid frequency exceeds certain
- LIMxxx% CODE:01 limits.
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
Power limitation due to over-voltage:
The message indicates that the user has set a power limitation
due to overvoltage (parameter U >(10 min)) in order to reduce the
maximum output power of the inverter when the reading of the
average grid voltage exceeds certain limits.
- LIMxxx% CODE:02
The sampling of readings is done every 10 minutes (U>(10min)).
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
Anti-islanding power limitation:
The message indicates that a power limitation is active because
a situation of "islanding" has been recorded.
- LIMxxx% CODE:03 LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
Power limitation due to low grid voltage:
The message indicates that an output power limitation may occur
since a low grid voltage (AC) condition has been recorded.
- LIMxxx% CODE:04 LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
The equipment can signal possible output power limitations which may
occur on the basis of:
- settings made by the user
- settings required by the grid standard of the country of installation
- protective devices inside the inverter
user interface.
