Parameters
s1 = Asymmetric P load sharing Set point
Points on graph
1. Genset A and Genset B share the load equally. Asymmetric P load
sharing would required Genset B to run below the minimum.
2. The load rises.
3. The load on Genset B will be more than the minimum if Genset A uses
asymmetric P load sharing. The power management system therefore
increases the load on Genset A until it reaches its asymmetric P load
sharing set point.
4. The load continues to increase. The power management system keeps
Genset A at its asymmetric P load sharing set point, and varies the load
on Genset B.
