Parameters
s1 = Asymmetric P load sharing Maximum
s2 = Load-dependent start
s3= Asymmetric P load sharing Set point
Points on graph
1. Genset A runs at its asymmetric P load sharing set point, and the load
on Genset B varies.
2. Genset B reaches the asymmetric P load sharing maximum. The power
management system shares the load equally between Genset A and
Genset B.
3. The load increases. The load on the gensets exceeds the load-
dependent start, and the power management system starts Genset C.
4. Genset C is connected and starts taking load. Genset A and Genset B
can run at their asymmetric P load sharing set point, while the load on
Genset C varies.
