Load Share Output

The generator uses the measured load share output to calculate per unitized average load level, and
uses that as the setpoint for its kW controller. Settings are provided for maximum voltage and minimum
voltage.

The BESTCOMSPlus Load Share Output screen is illustrated in Figure 63.

Parameter Selection

When it is not necessary for the DGC-2020HD to communicate with the AVR or GOV, these outputs may
be utilized for other purposes. Selectable parameters are listed in the Configurable Protection chapter.
Param Min corresponds to the minimum output voltage or current setting. Param Max corresponds to the
maximum output voltage or current setting.

Demand Start/Stop

The demand start/stop function operates in one of two modes: Per Unit Load or Spinning Reserve. When
Per Unit Load mode is selected, the DGC-2020HD issues start and stop requests based on per unitized
system load. When Spinning Reserve mode is selected, the DGC-2020HD provides extra generating
capacity by starting an additional generator that is already connected to the system.

The primary function of Demand Start/Stop is to provide start and stop request information to the
sequencing handler. Generator sequencing must be enabled in order for Demand Start/Stop to function. If
system load is above a set level and the corresponding start level timeout has been exceeded, a
corresponding start request is issued. If system load is below the delayed stop level and the stop timeout
has been exceeded, a stop request is issued.
