POWER MANAGEMENT AND WORKFLOW CHART
There are two kinds of power management mode: Equal load sharing and fixed power output.
11.1
EQUAL LOAD SHARING
Equal load sharing is active both in auto mode and semi-auto mode. In both cases, load sharing is
carried out via network bus.
There are two kinds of equal load sharing ways: active load sharing and reactive load sharing.
a)
Active load sharing: the real-time equal load sharing of active power of each unit on bus can be
adjusted via GOV or relay output.
b)
Reactive load sharing: the real-time equal load sharing of reactive power of each unit on bus can be
adjusted via AVR or relay output.
11.2
FIXED POWER OUTPUT
Each unit can be selected as running with fixed power. This can be done via digital input or
parameter setting.
The unit works in fixed power mode will automatically be set in SEMI-AUTO. Only one generator per
independent bus can run in this mode.
Active power output value and reactive power output value can be set, in addition, power factor
also can be set.
When the generator main switch is closed, the generator power will be increased to the fixed power
set-point.
The following figure shows the fixed power DG & SG on-load diagram in SG mode:
