摘要： A method and system for reducing a disturbance of an electric grid signal in a wind turbine is provided. The method includes providing a generator for the wind turbine system, and, coupling a power converter to the generator, the power converter. The power converter is configured to monitor at least one of a negative sequence component and a positive sequence component of a signal transmitted from an electric grid, determine if a disturbance exists based on the monitored signal, determine at least a portion of a magnitude of the negative sequence component of the signal, and, orient a voltage of the signal based on the determined magnitude negative sequence component to modify the instantaneous power flow through the power converter.

摘要： A method of conditioning tantalum capacitors on printed wire assemblies is disclosed. According to the method, each of the capacitors on an assembly is subjected to the same conditioning level during testing. To condition the tantalum capacitors, surge currents are induced in the capacitors in a controlled manner as a means of aging the capacitors so that they can be used without de-rating rating with low failure rates. The level of voltage, timing and current levels are set by circuitry used to perform the testing. The same circuits that are used with the capacitors in a system application are also used for the tantalum capacitor test circuit during the conditioning process.

摘要： An apparatus for cooling electrical protective devices comprises an electrical protective device mounted to at least one electrical terminal, wherein the electrical terminals are cooled to indirectly cool the electrical protective devices. A pressurized coolant source passes a coolant fluid through coolant passages attached to the electrical terminals, thereby cooling the electrical terminals. The cooled electrical terminals maintain the temperature of the electrical protection device within an appropriate operating temperature range. This cooling method may be used to increase the fuse power rating of a fuse array while maintaining electrical coordination between the fuses in the fuse array and electrical devices protected by the fuse array.
