An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold. Initiating the corrected actions when each operation parameter deviates beyond the corresponding operation threshold maintains the operation of the electric driven hydraulic fracking system.

An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

A turbine system that harnesses energy from natural atmospheric wind and water currents for power generation and storage in a power storage mode, and in a reverse switched operation, sources current to the turbine system from storage power to function in a propulsion mode to propel an associated structure (e.g., boat, aircraft).

Certain embodiments of the present application relate to a variable frequency drive (VFD) cabin for a pump configuration including a mobile trailer on which the VFD cabin is to be mounted. The VFD cabin generally includes a medium-voltage VFD and a ventilation system. In certain embodiments, the ventilation system is configured to generate an overpressure condition within the cabin to discourage the entry of dust and debris into the cabin. In certain embodiments, one or more components of the medium-voltage VFD are coupled to the floor of the cabin via a vibration damping system. In certain embodiments, the VFD cabin may be directly coupled to a chassis of the mobile trailer without an intervening suspension being provided between the VFD cabin and the chassis.

An apparatus for providing mobile electric power includes a power generation transport. The power generation transport includes an air inlet filter housing, an inlet plenum coupled to the air inlet filter housing, an exhaust collector, an exhaust implement coupled to the exhaust collector, a gas turbine, a generator driven by the gas turbine, and an elevating system configured to elevate the exhaust implement to convert the power generation transport to an operational mode, and lower the exhaust implement back down to convert the power generation transport to a transportation mode. The elevating system performs the elevating and the lowering without utilizing any external mechanical apparatus. The air inlet filter housing, the inlet plenum, the exhaust collector, the exhaust implement, the gas turbine, the generator, and the elevating system are mounted on the power generation transport.

Disclosed is air turbine charging system for electrically powered vehicle. The electrically powered vehicle includes air intake vents and air intake ducts that direct air inside the system with a specific force. The system further includes one or more air turbines coupled with one or more gears and one or more alternators. The air intake vents and air intake ducts direct air to cause rotation of an air turbine causing them and their coupled gears and alternators to rotate and cause an electric current. This electric current is used to charge the battery of the vehicle using a regulator that regulates power between alternator and battery. The amount of air intake from the air intake vents is varied automatically while the vehicle is on move based on predefined conditions. Moreover, there are two batteries associated with the system which are charged and are used alternatively for functioning of the vehicle.

A portable system for converting wind energy into electrical energy is disclosed. The disclosed system may include a frame hosting one or more conversion modules, arranged as desired. A given conversion module may include one or more wind energy conversion devices (WECDs), arranged as desired. The conversion modules may be electrically connected, directly or indirectly, with one or more downstream electrical energy storage elements (e.g., such as a battery or other capacitive element, optionally native to a host platform). In this manner, the disclosed system may be configured for use in storing and/or supplying electric power for downstream consumption by a host platform or otherwise. In a more general sense, the disclosed system may be utilized, for example, for micro-generation of renewable electrical energy from wind.

A supercharging system to be mounted in a vehicle including an engine, a driving operator, and an electric power storage unit includes an exhaust turbine, an intake compressor, an electric power converter, and a controller. The exhaust turbine generates electric power. The intake compressor feeds compressed intake air to the engine. The electric power converter supplies electric power from the electric power storage unit and recovers electric power to the electric power storage unit via an electric power path between the exhaust turbine and the intake compressor. The controller acquires a target value of compression power of the intake compressor, based on an operation of the driving operator and an operating state of the engine, and controls the electric power converter such that electric power corresponding to a difference between the acquired target value and the generated electric power is supplied from or recovered to the electric power storage unit.
