摘要： The objective of this patent is to describe novel methods and device systems for detecting the fault-cleared state in a shunt compensated transmission line. The methods are applicable in all types of transmission line types and faults, in any type of reclosure mechanism, and can be implemented in existing devices such as relays and not need sophisticated equipment. One application of detecting the fault-cleared state is adaptive reclosure in which case, substantial improvement in transmission system reliability and benefits in protection can be achieved.

摘要： The invention relates to a device (1) for influencing reactive-power flows in multi-phase alternating current systems, comprising a plurality of thyristor-controlled or thyristor-switched coil branches, each of which comprises a first partial coil (4, 4', 4") and a second partial coil (5, 5', 5"), a first partial coil (4, 4', 4") and a second partial coil (5, 5', 5") forming a structurally independent coil subassembly (13, 13', 13"). The essential feature consists in the inductance factor of the first partial coil (4, 4', 4") being especially at least 10 percent greater than the inductance factor of the second partial coil (5, 5', 5") and in the second partial coil (5, 5', 5") of a coil subassembly (13, 13', 13") being structurally arranged on top of the first partial coil (4, 4', 4") or the second partial coil (5, 5', 5") being structurally arranged in a core region of the first partial coil (4, 4', 4"). The disclosed device (1) for influencing reactive-power flows has a design that is as compact as possible, meets increased stability requirements especially for dynamic loads, and allows production costs and operating expenses to be reduced or kept to a minimum.

摘要： The present invention relates to a method for controlling a voltage level of a power supply grid operationally connected to a source of electrical power, the method comprising the steps of determining a short circuit impedance of the power supply grid at a point of common coupling, calculating, using the determined short circuit impedance, a gain value of the power supply grid, and controlling the grid voltage level in accordance with the calculated gain value by applying said gain value as a gain parameter in a voltage controller. The method according to the present invention may be implemented as a method for configuring a voltage controller once and for all, or it may be implemented as a method for adaptively adjusting a gain of a voltage controller.

摘要： The invention relates to a module assembly for the application-specific construction of power factor correction systems, filter systems, and absorption circuit systems in selectively non-choked, choked, protective or thyristor-connected design, comprising a busbar system, fuse holders, switch components, at least one choke, and power capacitors. According to the invention, a first module unit is provided, comprising a first section for receiving busbars, standard fuse holders, fuses, a busbar cover as protection against accidental contact with the busbar and/or fuses, and a second, trough-like section for receiving switch components or switch means such that they can be mechanically fixed and electrically contacted. A second module unit is designed to receive one or more in particular switchable capacitor winding blocks, wherein the second module unit encloses the at least one winding block, insulating the same. The first and the second module unit each have a base region, wherein mechanical and/or electrical connections are led via apertures or openings in the respective base regions, such that either a back-to-back assembly with direct docking of the first and second module units can be effected, or a compact choke set with connecting elements can be mechanically received in an electrically insulated manner between the first and second module units using the apertures or openings in the respective base region of the first or second module unit, and can be electrically connected.

摘要： The present techniques include methods and systems for detecting a failure in a capacitor bank of an electrical drive system. Embodiments include using discharge resistors to discharge capacitors in the capacitor bank, forming a neutral node of the capacitor bank. In different capacitor configurations, the neutral node is measured, and the voltage is analyzed to determine whether a capacitor bank unbalance has occurred. In some embodiments, the node is a neutral-to-neutral node between the discharged side of the discharge resistors and a neutral side of the capacitor bank, or between the discharged side of the discharge resistors and a discharged side of a second set of discharge resistors. In some embodiments, the node is a neutral-to-ground node between the discharged side of the discharge resistors and a ground potential.
