  • System and method for dynamic voltage regulation of an engine on a variable frequency bus
    Patent number: 11177664
    Abstract: A system and method for variable frequency voltage regulation is presented. The system includes a variable frequency bus and a variable frequency load directly connected to the variable frequency bus. A plurality of variable frequency gensets are directly connected to the variable frequency bus. Each variable frequency genset includes a genset controller configured to select set points based on a selected frequency response curve of the variable frequency bus. A variable frequency voltage regulator is configured to regulate an electrical output of the variable frequency generator based on the selected set points. The system includes a voltage regulation controller configured to determine a desired bus frequency based on the variable frequency load, and determine an optimal frequency response curve based on the desired bus frequency and a frequency response model of each VFG. The selected frequency response curve is updated based on the determined optimal frequency response curve.
