GENERATOR SET ADAPTIVE DROOP CONTROL METHOD
First Claim
1. A method of controlling a plurality of gensets during a failsafe condition, the method comprising:
- operating a remainder of the gensets according an adaptive droop control scheme, the adaptive droop control scheme adjusting the frequency of each droop genset to match that of one or more isochronous gensets, and varying the load of each droop genset with respect to frequency for lower-range loads and upper-range loads.

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.

9. An adaptive droop control system for controlling a plurality of gensets during a failsafe condition, the adaptive control system comprising:
-
at least one controller in electrical communication with one or more of the plurality of gensets, the common bus, and the load, the controller being configured to; operate one or more of the gensets according to an adaptive droop control scheme, the adaptive droop control scheme configuring the controller to adjust the frequency of each droop genset to match that of one or more isochronous gensets, and vary the load of each droop genset with respect to frequency for lower-range loads and upper-range loads. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A genset system, comprising:
-
a plurality of gensets, each genset having a primary power source and an electric machine configured to generate electrical power; a common bus coupled to each of the gensets and configured to communicate the electrical power generated by the gensets to a connected load; and at least one controller in electrical communication with one or more of the plurality of gensets, the common bus, and the load, the controller being configured to operate one or more of the gensets according to an adaptive droop control scheme during a failsafe condition, the adaptive droop control scheme varying load with respect to frequency for lower-range loads and upper-range loads. - View Dependent Claims (18, 19, 20)
