LDSS dynamic
Dynamic characteristic
= [(max. generator load – min. generator load) * dynamic] + (min. generator
load)
Dynamic power level
= (dynamic characteristic) * (generator rated power)
Constants
Low dynamic
= 25 %
Moderate
dynamic
= 50 %
High dynamic
= 75 %
☼
Example for moderate dynamic
• Dynamic characteristic = [(80 % – 40 %) * 50 %] + (40 %) = 60 %
•
• Dynamic power level = (60 %) * (200 kW) = 120 kW
