Abstract: Disclosed is a gerotor pump including an inner gear mounted on a first axis, an outer gear mounted on a second axis and meshing internally with the inner gear in an offset manner, and an electrical motor including a rotor and a stator having a radial gap therebetween in a radial direction. The pump also includes a spindle fixedly coupled to the outer gear to facilitate maintaining the radial gap. The spindle is rotatably coupled for rotation about the second axis. The spindle aids in maintaining a consistent radial gap during operation of the gerotor pump. The inner gear may be coupled to a drive shaft for driving the gears. The gerotor pump may be driven via an electric or mechanical driver. A pressure plate may also be positioned adjacent the gerotor gears and within the housing. The spindle and pressure plate help secure the pump parts both axially and radially.

Abstract: Systems and methods described herein may be used to search for a minimum load overshed in a power system. For example, a control system includes memory and a processor operatively coupled to the memory. The processor may obtain an amount of power consumed by each load in a total set of loads in a microgrid. The processor may detect a difference between the amount of power generated and the amount of power consumed. The processor may select a subset of loads to shed from the total set of loads by searching a tree of potential load shed amounts to substantially balance the amount of power generated with the amount of power consumed. The processor may send one or more signals to one or more electronic devices to cause the selected subset of loads to be shed.

Abstract: Disclosed herein are systems for maintaining protection of electric power delivery systems in the event of a control power failure or other anomaly. A reliable power module conditions electric power from multiple independent sources and provides electrical operational power to electric power delivery system protective loads. The reliable power module includes an energy storage device for providing operational power even upon loss of all control power sources. The energy storage may be sufficient to ride through expected losses such as a time to start up backup generation. The energy storage may be sufficient to power a trip coil. Thus, electric power system protection is maintained even upon loss of control power. A discharge circuit is provided to allow an operator to de-energize an energy storage device.

Abstract: The present disclosure pertains to systems and methods for analyzing traveling waves in an electric power delivery system. In one embodiment, a system may comprise a traveling wave identification subsystem to receive electric power system signals and identify a plurality of incident, reflected, and transmitted traveling waves. A first traveling wave may be selected from the incident and transmitted traveling waves, and a first distortion may be determined. A second traveling wave subsequent to the first traveling wave, may selected from the incident traveling waves and a second distortion may be determined. A traveling wave analysis subsystem may compare the first distortion and the second distortion and determine whether the first distortion is consistent with the second distortion. A protective action subsystem may implement a protective action based on a first determination that the first distortion is consistent with the second distortion.

Abstract: A transportation device for an offshore platform, including a vessel and a floating structure which are fixedly connected. The floating structure is placed on a sea surface and is configured to assist the vessel to sail. The floating structure is provided with an adjustment mechanism which is configured to adjust the floating structure to rise and fall relative to the sea surface. A rail is arranged on the vessel and is in sliding connection with the topside module, so that the topside module slides onto the vessel from land. During the transportation of the topside module, the buoyancy of the floating structure is adjusted through the adjustment mechanism, so that the floating structure provides sufficient anti-rolling moments beside the vessel, thereby reducing the vibration of the topside module caused by the winds and waves during the sailing and reducing the potential damage to the topside module.
