Abstract: Unique systems, methods, techniques and apparatuses for a ZVT ZCT resonant converter with a variable resonant tank are disclosed. One exemplary embodiment is a system comprising a bidirectional resonant converter comprising an input/output terminal, a switching device coupled with the input/output terminal, a resonant circuit coupled with the switching device and including a variable inductor, an output/input terminal coupled with the resonant circuit, and a DC biasing circuit operatively coupled with the variable inductor. The variable inductor comprises a toroidal core, a first winding wound around the toroidal core and coupled with the switching device and the output/input terminal, a second core structured to overlap a portion of the toroidal core, and a second winding wound around the second core and coupled with the DC biasing circuit. The DC biasing circuit is controllable to vary the inductance of the variable inductor by saturating a portion of the toroidal core.

Abstract: An exemplary control system performs a control and fault analysis method in a thermal power plant using plant data specifications during normal operation of the plant. The method includes obtaining information for at least one set point from the plant data specification which includes a list of process parameters and process outputs. One or more control loops are controlled by providing set points for control based on the information obtained for the at least one set point to operate the thermal power plant and identifying gaps in controlling the one or more control loops in the thermal power plant specification and at least one set point is iteratively manipulated to meet the demand. Further, the plant data specification is updated based on the manipulated at least one set point used to meet the demand, and the updated plant data specification is used for controlling the plant to meet the demand.

Abstract: The method relates to an electric device comprising at least two electrodes which are separated by dielectric part. At least one of said electrodes is arranged to be at a floating potential. The dielectric part comprises at least one turn of at least one non-impregnatable electrically insulating film between two neighboring electrodes. The electrodes are bonded to adjacent turns of non-impregnatable insulating film, and adjacent turns of non-impregnatable insulating film, if any, are bonded to each other, so that the turns of non-impregnatable insulating film and the electrodes form a solid body. The invention further relates to a method of manufacturing an electric device, where bonding of at least one turn is performed upon forming of said turn, so that the bonding of said turn to the turn/electrode underneath will commence before said turn has been completely covered by the next turn.

Abstract: A power distribution system for off-shore natural resource platforms includes an off-shore medium voltage direct current (MVDC) power bus. The MVDC power bus includes multiple power bus segments, each of which may be connected to one or more other power bus segments via a corresponding circuit breaker. Each power bus segment may also be electrically coupled to an off-shore renewable energy source, such as a wind farm, and/or an off-shore drilling platform. The off-shore drilling platforms may include local power distribution systems electrically connected to a corresponding power bus segment via a circuit breaker to receive power from the MVDC power bus and supply power to local equipment of the off-shore drilling platform.

Abstract: Unique systems, methods, techniques and apparatuses of fault location in DC power distribution systems are disclosed. One exemplary embodiment is a DC power distribution system comprising at least one DC power distribution network and at least two protective devices operatively coupled to the DC power distribution network. Each protective device is structured to sense one or more electrical characteristics associated with the DC power distribution network and to controllably interrupt current through the DC power distribution line. A control system is structured to determine the location of a high impedance fault between two of the protective devices using one or more electrical characteristics sensed by the two protective devices to calculate the inductance and resistance of the portion of the DC power distribution line between one of the protective devices and the high impedance fault.
