4.5.1 Configure Generator Monitoring
4.5.1.1 Generator Operating Ranges: Voltage / Frequency / Busbar
The operating voltage/frequency/busbar parameters are used to check if the values are
in range when performing a dead bus closure and synchronization of the generator.
Busbar 1 must be within this ranges to synchronize the generator to the busbar.
It is recommended to configure the operating limits within the monitoring limits.

Description
5800 Upper voltage limit
(Generator maximum
operating voltage limit)
2 100 to 150%
[110%]
(Hysteresis: 1%)
The maximum permissible
positive deviation of the generator
voltage from the generator rated
voltage (parameter
╚═▷ 1766 ) is
configured here.
This value may be used as a
voltage limit switch. The
conditional state of this switch
may be used as a command
variable for the LogicsManager
(02.03).
5801 Lower voltage limit
(Generator minimum
operating voltage limit)
2 50 to 100%
[90%]
(Hysteresis: 1%)
The maximum permissible
negative deviation of the
generator voltage from the
generator rated voltage
(parameter
╚═▷ 1766 ) is
configured here.
This value may be used as a
voltage limit switch. The
conditional state of this switch
may be used as a command
variable for the LogicsManager
(02.03).
5802 Upper frequency limit
(Generator maximum
operating frequency
limit)
2 100.0 to 150.0%
[105.0%]
(Hysteresis: 0.05%)
The maximum permissible
positive deviation of the generator
frequency from the rated system
frequency (parameter
╚═▷ 1750 )
is configured here.
This value may be used as a
frequency limit switch. The
conditional state of this switch
may be used as a command
variable for the LogicsManager
(02.04).
5803 Lower frequency limit
(Generator minimum
operating frequency
limit)
2 50.0 to 100.0%
[95.0%]
(Hysteresis: 0.05%)
The maximum permissible
negative deviation of the
generator frequency from the
rated system frequency
(parameter
╚═▷ 1750 ) is
configured here.
This value may be used as a
frequency limit switch. The
conditional state of this switch
may be used as a command
