    摘要: The present invention concerns a method of operating a wind park having a plurality of wind power installations. The invention further concerns a wind power installation having an electrically excited generator and a wind park having a central apparatus for controlling the park. Therefore the object of the present invention is to provide a method of operating a wind park having a plurality of wind power installations, a wind power installation having an electrically excited generator and a wind park having a central apparatus for control of the park, wherein the execution of operational procedures is effected with a restricted or reduced power draw from the network (reference power). A method of operating a wind park comprising a plurality of wind power installations characterized in that the operational procedures of each wind power installation are controlled in such a way that electrical power is taken from the network only up to a predeterminable maximum value.

    摘要: A power converter utilizes an inverter operating at a frequency near 30 kHz to produce an RF voltage which is divided by a reactive voltage divider, one portion of the divider including a saturable reactor having a control winding which is driven by a negative feedback current from a level sensing circuit connected to the converter output. DC voltage is provided by a bridge rectifier and filter connected across the saturable reactor. The circuit is especially useful for supplying electrical power efficiently to instrumentation on multikilovolt transmission lines where a transformer cascade is used to conductively isolate apparatus operating at the potential of the transmission line from a ground level power source.

    摘要: A power tool comprising a housing, an interface configured to receive a battery pack, a trigger for user control of power tool operation, at least one sensor configured to measure an operational characteristic of the power tool, and a controller. The controller is configured to receive a control signal from the trigger, control the power tool in response to the control signal, receive power tool operational data from the at least one sensor indicative of the operational characteristic of the power tool, and provide additional energy to the power tool via an auxiliary energy supply within the power tool housing based on the operational characteristic of the power tool.

    摘要: An annex supply system for an electrical power plant includes an energy extraction network configured to receive AC current from a main production unit, a main auxiliary network coupled to the extraction network, and a secondary supply unit. The secondary unit includes a storage element coupled to a means for reversible conversion from direct to alternating current that is controllable to selectively (i) charge the storage element from the main auxiliary network, and (ii) discharge energy from the storage element to the main auxiliary network. The secondary unit is configured to (i) provide a first power profile at least sufficient to provide services to a transmission network, and/or (ii) provide to the main auxiliary network a second power profile required to operate auxiliary equipment in case of inoperability of a normal power supply source of the main auxiliary network.
