Imagine that you have just reached the highway and set your speed to 60 miles per hour. In facilities with a high demand, generator sets can be electrically paralleled for more efficient load sharing and load response. At the time a communication break is detected, the generator sets in the majority group go into modified isochronous operation, while the generator sets in the minority group go into adaptive droop, initially “freezing” at their last load level. The controllers communicate via a dual-redundant Ethernet network. In this case the two CAT’s, both in Isochronous. Describe primary components of governing systems, their features and functions. As changes in the load occurs between 6 minute optimization cycles, the DMC490 ensures that it took into account enough generation loading margin known as “Isochronous Generator Margin” or “Isoc Margin” to support the addition to the load. Generator submittal data, attached to this addendum. The Cat® C1.
