Abstract: A method for monitoring an electric power source changeover switch, including a step of identifying all of the combinations of operating modes and availability states of the power sources, a step of associating a configuration of a state of switches with each combination, a step of watching for a change in configuration. Upon a change in configuration, a step of controlling the switches is executed in order to place the switches in a state complying with the configuration. In the absence of a change in configuration, a step monitors the compliance of the configuration with the actual state of the switches. A method further including monitoring a source changeover switch implemented in a test device, and to a source changeover switch implementing such a method.

Abstract: Systems and methods for controlling power flow to and from an energy storage system are provided. One energy storage system includes an energy storage device and a bidirectional inverter configured to control a flow of power into or out of the energy storage device. The energy storage system further includes a controller configured to control the bidirectional inverter based on one or more signals received from the generator set coupled to the inverter via an AC bus. The controller is configured to, based on the one or more signals, control the bidirectional inverter to store power generated by the generator set in the energy storage device and transmit power from the energy storage device to a load driven by the generator set to maintain the generator set within a range of one or more operating conditions.

Abstract: An uninterruptable power supply (UPS) system for providing power to a load coupled to a utility power source is provided. The UPS system includes a doubly-fed induction generator (DFIG), a rechargeable energy storage system, a first inverter, and a controller in communication with the DFIG and the first inverter. The DFIG includes a stator and a rotor coupled to the load. The stator and rotor are magnetically coupled together. The DFIG generates an auxiliary power output. The first inverter is coupled between the rotor and the rechargeable energy storage system. The controller detects a power disturbance associated with the utility power source and controls the first inverter to provide an excitation input to the rotor in response to the power disturbance. The DFIG provides the auxiliary power output to the load based on the excitation input.

Abstract: A safety system includes a vehicle having a cab and a compartment rearward of the cab, an engine that provides motive power to the vehicle, a generator positioned in the vehicle so as to supply electrical energy to the compartment, an alarm positioned in or on the vehicle so as to be cooperative with the engine and the generator, an alarm acknowledge switch positioned in or on the vehicle, a shore power connection on the vehicle, and a control module positioned in or on the vehicle so as to selectively activate or deactivate the alarm or to deactivate the generator when certain conditions occur. The generator has an on/off switch so as to turn the generator either on or off. The alarm is activated when the generator is turned on and the engine is not running. The alarm acknowledge switch is activatable as to turn the alarm off. The shore power connection is adapted to be connected to a source of electrical energy exterior of the vehicle.

Abstract: Systems and methods where a power-packet-switching converter is used to interface a synchronous AC connection (e.g. to the utility power grid, or to a microgrid) to a DC source (e.g. a battery bank, or possibly a photovoltaic cell bank) and to a non-synchronous AC power source (e.g. a wind turbine or a motor-generator). The power-packet-switching converter not only provides voltage conversion and other functions (e.g. DC to AC, AC-AC with frequency change, 2-phase to 3-phase, power factor correction etc.), but also provides phase correction to convert asynchronous AC to synchronous AC.

Abstract: A load management apparatus for use with an electrical system being powered by an electrical generator selectively adds and sheds loads on the electrical generator to prevent overloading of the electrical generator. The load management apparatus learns the load profile for each load during a learning mode and executes one or more load shed processes to control which electrical loads are loading the electrical generator.

Abstract: Electrical power systems and methods using bidirectional power converters to provide, among other functions, uninterruptible power supplies for loads such as cell towers. The power-packet-switching power converter can be connected, for example, to a photovoltaic array, batteries, and a critical load such as a cell tower. An AC generator can also be connected in order to power the cell tower and/or to charge the batteries as needed. Green energy utilization is maximized, power conversion efficiency is increased, and system costs are decreased, by having only a single power conversion stage for all conversions.
