摘要： A generator enclosure system provides for tool-less removal of protective panels. The panels are configured to lock in place and unlock by a technician using only their hands. Side panels interlock with front and back panels. At least the front panel may be removed by actuating, by hand, a lever on a locking mechanism and lifting the panels up and away from the generator enclosure system.

摘要： Systems and methods for reducing produced gas venting from a hydrocarbon well, in which the engine driving the pump burns produced gas from the well, the engine made to increase its throttle to burn more gas in response to an increased gas pressure indicator, and an external load such as a generator directed to increase the load on the engine and maintain the engine operating within a desired revolutions-per-minute range to avoid redline condition.

摘要： There are described methods and systems for synchronizing at least two generators for an engine. A first generator is mechanically coupled to the engine. A power source is connected in parallel to the first generator and to a second generator, the second generator mechanically uncoupled from the engine, the power source connected across a same respective phase of a stator in the first generator and the second generator. Power from the power source is applied to the first generator and the second generator to align a respective rotor to the respective phase in each generator and cause the first generator and the second generator to be in-phase. The second generator is then mechanically coupled to the engine.

摘要： A battery management system is configured to, in an island mode, cause a frequency adjustment (e.g., by 3 Hz) to voltage in the power system based on a state of charge. The frequency adjustment signals assets (e.g., loads, generators, energy storage devices) electrically coupled to a battery system to reduce or increase power. If the state of charge is below a threshold value, the frequency adjustment may signal a load to be decreased, power generation of a generator to be increased, or power output of an energy storage device to be increased. If the state of charge is above a threshold value, the frequency adjustment may signal a load to be maintained or increased, power generation of a generator to be decreased, or power output of an energy storage device to be decreased. The frequency adjustment may be calculated automatically as a function of the state of charge.

摘要： In one embodiment, a generator includes a rotor configured to rotate in cooperation with a stator to generate electrical power. A sensor, which is supported by the rotor, is configured to generate a trigger signal indicative of a position of the rotor. A communication interface is configured to receive the trigger signal from the sensor of the rotor and receive data indicative of an output of the generator. A controller supported by the rotor or configured to perform a phase analysis of the trigger signal and the output of the generator and calculate a power angle for the generator based on the phase analysis.

摘要： A dual engine generator has two engines and two inverters and two alternators configured within an inner enclosure. An outer enclosure extends around the inner enclosure to create plenums for airflow. Cooling airflow enters through the outer cover and flows through the plenums and into the inner enclosure to cool the components therein. Airflows out of the inner enclosure and into the plenums and finally exhausts from the outer enclosure. The outer enclosure may have rounded sides to form a pill shaped enclosure. The outer covers are configured to deflect or flex in high wind condition and protect the inner enclosure. The engines are configured above the alternator and inverter and a flow of air reduces heat from the engines from overheating the other components. The mufflers are within the plenums and a flow of exhaust air from within the inner enclosure is directed over the mufflers.

摘要： A generator assembly suitable for being carried on the back of a human comprising an internal combustion engine an alternator and a shaft driven by said engine and driving said alternator wherein when said generator assembly is being carried on the back of a human said shaft is substantially parallel to a longitudinal axis of said human. This enhances the manoeuvrability of the assembly. Preferably the assembly comprises a generator module having an engine and an alternator coupled directly by a common shaft, the generator module being attached to a frame of the assembly at only two longitudinally spaced-apart positions.
