Abstract: A fault-current limiting device having an input voltage node configured to receive a first voltage signal from an energy source, such as a battery, and an input reference node configured to receive a reference signal from the energy source. The device further includes a first switch coupled between the input voltage node and an output voltage node and a second switch coupled between the input reference node and an output reference node. The device further includes a current sensor circuit coupled to the output voltage node and coupled respectively to the first switch and the second switch wherein the current sensor circuit is configured to open the first and second switches in response to sensing a current signal at the output voltage node that exceeds a threshold current (e.g., a transient fault current).

Abstract: Methods and apparatus for power generation and distribution according to various aspects of the present invention may operate in conjunction with a control system for controlling electrical power flowing between a main electrical grid providing main electrical grid power having a frequency, a supplemental power system, and a load. The control system may operate in conjunction with a switch system, wherein the switch system selectively connects the supplemental power system to the main electrical grid. A controller may be responsive to the main electrical grid power frequency and control the switch system. The controller may compare the main electrical grid power frequency to a first threshold and autonomously cause the switch system to connect the supplemental power system to the main electrical grid in response to the frequency of the main electrical grid power crossing the first threshold.

Abstract: Systems, methods, and building block modules for modular power generation facilities are disclosed. A modular power generation facility includes a plurality of primary modules and a control system. Each primary module includes eight primary corners and an interior space. The modules are positioned in a vertical stack and are attached together to form a substantially modular enclosure for the generation of electricity.

The control system communicates with the gen-set modules to coordinate the engine-generators as a unit and to control the loading of each of the generators in response to a power load demand. The control system is disposed in one or more of the primary modules with at least part of the control system being disposed in the switchgear module.
