摘要： Systems and methods for managing reactive power during low voltage ride through are provided. Responsive to detecting a fault on a power grid, a controller may identify a power regulation mode of the generator system. The controller can switch the power regulation mode to an offset power regulation mode of the generator system responsive to identifying the power regulation mode. The controller may adjust a value of a parameter of the generator system from a normal value to an offset value, wherein the parameter is selected based on the offset power regulation mode. The controller can maintain the value of the parameter as the offset value for a period of time. After the period of time, the controller can modify the value of the parameter from the offset value to the normal value, and the power regulation mode from the offset power regulation mode to the identified power regulation mode.

摘要： Systems and methods for controlling and methods for controlling the power factor in a generator system are provided. In some embodiments, the generator system includes one or more generators configured to supply power to a power grid, an automatic voltage regulator configured to regulate a voltage of an output of the generator to a set voltage and regulate a power factor of the output to a set power factor, and a controller. The controller is configured to detect a fault on the output and to adjust the set power factor of the automatic voltage regulator based on the fault. The controller is further configured to ramp the set power factor from the adjusted value to an initial value over a set period of time.

摘要： A generator set comprises an engine including a crankshaft rotatable in a first direction about a longitudinal axis of the generator set, and a generator including a generator shaft. A gearbox is positioned between the engine and the generator, all mounted on a chassis. The gearbox couples the crankshaft to the generator shaft. The gearbox includes a gearbox housing having a first end and a second end. The first end is coupled to an engine first end and the second end is coupled to a generator first end. The gearbox also includes a gear set including a plurality of gears, a first gear shaft coupled to a crank shaft first end, and a second gear shaft coupled to a generator shaft first end. The crankshaft and at least a portion of the plurality of gears, and the generator shaft are axially aligned along the longitudinal axis of the generator set.

摘要： A method of reducing cold startup time of a genset which includes an engine and a generator for providing a requested power to a utility grid or load comprises determining if the generator is electrically coupled to a utility grid or load. In response to determining the generator is electrically coupled to the utility grid or load, a speed bias value is controlled in response to the power being produced by the genset. The speed bias signal represents a difference between a target power output and a current power output of the genset. The power of the engine is controlled using the speed bias value.

摘要： Systems and methods for detecting abrupt voltage changes and supplying reactive power support are provided. In some embodiments, a genset connected to a power grid can identify a maximum voltage value and a minimum voltage value. The maximum voltage value and the minimum voltage value are based on an average of a plurality of mains voltage values. The genset may detect an abrupt voltage change by determining whether an instantaneous mains voltage value is above the maximum voltage value or below the minimum voltage value. The genset can adjust an amount of reactive current either supplied to the power grid or consumed by the genset for a period of time, responsive to detecting the abrupt voltage change.

摘要： A genset module coupling assembly includes a cross-bar of a module chassis oriented orthogonal to an engine neutral axis of vibration defined by an engine mounted on an engine chassis, a first bracket coupled to the cross-bar on a first side of the engine neutral axis of vibration, and a second bracket coupled to the cross-bar on a second side of the engine neutral axis of vibration. The first bracket and the second bracket are positioned to minimize communication of vibrations from the engine chassis to the module chassis.
