Publication number: 20240093663Abstract: A DC power plant generating DC power from a variety of engines including a Stirling cycle engine. The DC power plant includes a relatively small start-up power source that is discontinued after the engine is running. A method for producing DC power for a load including starting up an engine using power supplied by a relatively small power supply supplemented by a capacitor bank, providing output from the engine to a generator, producing alternating current (AC) power by the generator, converting the AC power to direct current (DC) power, disabling output of the DC power during a first set of pre-selected conditions, limiting a rate of change of current of the DC power during a second set of pre-selected conditions, reducing conducted and radiated emissions of the DC power, disconnecting the DC power from the load under a third set of pre-selected conditions, and providing the DC power to the load.Type: ApplicationFiled: November 20, 2023Publication date: March 21, 2024Inventors: Andrew A. Schnellinger, James R. Lowell, Bryan A. Finseth, Christopher L. Barber, Jason M. Sachs, Donald J. Lucas, Shannon Prescott, Jeffrey W. Kite, Andras K. Fekete, Douglas R. Adams

Publication number: 20230198267Abstract: A method for determining when a connection of a power system to a grid has been disconnected. The method includes the power system supplying a first amount of reactive power to the grid to which the power system is connected, and the power system determining if there is a frequency change within the grid. This includes if the frequency change does not exceed a predetermined threshold, the power system supplying a second amount of reactive power to the grid, and if the frequency exceeds a predetermined threshold, the power system supplying a first amount of reactive power to the grid.Type: ApplicationFiled: December 21, 2022Publication date: June 22, 2023Inventors: Donald J. Lucas, Christopher L. Barber, Xiaorong Xia
