Abstract
A method of controlling a plurality of gensets during a failsafe condition is provided. The method may include operating one or more of the gensets according to a modified isochronous control scheme, and operating a remainder of the gensets according an adaptive droop control scheme. The modified isochronous control scheme may include varying the frequency of each isochronous genset with respect to load for lower-range loads and upper-range loads, and maintaining the frequency of each isochronous genset at nominal frequencies for mid-range loads. The adaptive droop control scheme may include adjusting the frequency of each droop genset to match the frequency of the isochronous gensets, and varying the load of each droop genset with respect to frequency for lower-range loads and upper-range loads.
