Abstract: An apparatus is provided for modifying a crankshaft angle of an internal combustion engine (ICE). An energy converter is configured to be connected to a crankshaft of the ICE. An energy storage unit is configured to deliver energy to the energy converter when the energy converter acts as a motor, and to store energy output from the energy converter when the energy converter acts as a generator. The controller is configured to calculate a current ideal crankshaft angle, calculate a current slip angle using an output of a crankshaft angle sensor, activate the energy converter as a motor to increase the current crankshaft angle when the current slip angle is greater than a predetermined upper threshold value, and activate the energy converter as a generator to decrease the current crankshaft angle when the current slip angle is less than a predetermined lower threshold value.

Abstract: A medium voltage inrush current (MVIC) regulator and interconnection control system for interposing between a distributed power generation facility and a utility grid. The facility has a designated generator step-up (GSU) transformer and is connected to the utility grid at a point of interconnect. The system includes a pre-insertion impedance injection transformer, a low voltage first switch connected between the pre-insertion transformer and secondary coils of the designated GSU transformer, a medium voltage second switch connected inline between the pre-insertion transformer and primary coils of the designated GSU transformer, and a controller. In response to restoration of the utility grid following a loss-of-grid event, the controller opens and closes the first and second switches according to an automated pre-energization switching sequence such that magnetic flux in the designated GSU transformer occurs at a reduced rate, thereby reducing inrush of current and undesirable power quality phenomena

Abstract: A method of controlling a power system that includes an electrical machine, e.g., wind turbine generator, a power converter, a DC circuit and a dynamic braking system (DBS) having a braking circuit having a braking resistor and being connected in series to the DC circuit, is provided. The method includes operating the DBS and controlling operation of the electrical machine based on a prevailing temperature of the braking circuit, stopping the electrical machine and controlling the electrical machine to be restarted at its rated output power once the prevailing temperature of the braking resistor reaches or falls below a lower temperature threshold. The electrical machine may be restarted at a lower output power and after restarting, its output power can be increased based on a power starting profile as the braking resistor cools.

Abstract: In an example, a control system for controlling a generator and providing an alarm upon detection of a fault condition. The control system includes a control relay, which includes a normally-open (NO) contact pair and a normally-closed (NC) contact pair, between the transfer switch and a controller. The NO contact pair is provided by a NO contact and a common contact, and the NC contact pair is provided by a NC contact and the common contact. The controller can receive signals indicative of a state of the contact pairs of the control relay and, based on the signals, determine whether to activate the generator and/or activate an alarm system.

Abstract: There is provided a vehicle-power-generator control apparatus and the control method thereof that does not notify a passenger of any erroneous alarm indicating an abnormality in an electric power generator, even when a power-generation stop command is received. it is determined that a vehicle power generator is not rotating, when the rotation speed, of the vehicle power generator, that is detected based on a power-generation voltage generated across an armature winding of the vehicle power generator is the same as or lower than a predetermined value; there is generated a power-generation stop holding signal obtained by delaying by a predetermined time a time point at which a power-generation stop signal, generated when the decoded command signal is a power-generation stop command signal for stopping electric-power generation, stops; then, the non-rotation determination signal is masked and invalidated, based on the power-generation stop holding signal.

Abstract: Systems and methods for controlling a generator set are disclosed herein. The method includes determining a state of local modes selectable via a local interface proximate to the generator set. The local modes include a local standby mode and a local remote enabled mode. The method also includes determining a state of a plurality of remote modes using a command from a device remote from the location of the generator set in response to determining the remote enabled mode is active. The method includes, in response to determining the local standby mode is active, the remote enabled mode is active, and one of the remote modes is active, determining whether to activate or stop the generator set based on the active remote mode and disabling the local standby mode from controlling activation of the generator set.

Abstract: At least one embodiment relates to a cogeneration system configured to be coupled to an electrical input of a building and configured to be coupled to a heating or cooling system of a building. The cogeneration system can comprise a generator configured to generate electrical energy. There can be also a fluid output and a fluid input that passes through the generator and configured to absorb heat from the generator. There can also be an electrical output coupled to the electrical input of the building wherein when the generator is operational, the engine creates both heat and electricity. There can also be a processor in communication with the generator, wherein the processor controls when the generator turns on and off based upon the amount of heat or cooling needed, the cost of fuel and the existing electrical rates. These costs can be obtained using communication with real time rates over the internet.

Abstract: A method of reducing cold startup time of a genset includes providing a lubricant to the genset at predetermined time intervals before a genset startup. The lubricant is heated to a predetermined lubricant temperature using an external heating system. A high temperature coolant of the genset is heated to greater than a predetermined high temperature coolant temperature. The speed of the engine is ramped to a target speed continuously without pausing at a speed lower than the target speed. Genset electrical parameters of the genset are synchronized to utility grid or load electrical parameters of the utility grid or load. The genset is electrically coupled to the utility grid or load such that the synchronizing and electrically coupling are performed within a predetermined synchronization time. A fueling rate and a spark timing is adjusted based on a power being produced by the genset.
