Voltage control at windfarms

Номер: US20120010756A1
Принадлежит: General Electric Co

A voltage control arrangement for a system of multiple windfarms with transmission lines. Voltage is regulated at a point of regulation on the system, such as a high voltage substation or other system bus. Regulation is achieved at the point of regulation by sensing the voltage, comparing to a reference voltage, and adjusting the reactive power output of the wind turbines and other equipment in the system. The regulation point may be shifted to another point if needed to respect voltage limits at that points of the system after attempting to shift reactive load to restore voltage within limits at the other points in the system. The reference voltage may be adjusted to minimize losses for the system of multiple windfarms and transmission lines. A loss optimizing algorithm is applied to the combined multiple windfarm and transmission line to shift reactive load among local windfarms to minimize losses and to shift reactive load among individual wind turbines within an individual windfarm.

A multi-port, isolated battery recharge system which comprises a transformer having one or more secondary windings, each of which connects to a non isolated AC to DC converter, wherein the primary of the transformer connects to medium voltage utility power. The present application claims priority to and the benefit of U.S. Provisional Application No. 62/802,168, filed Feb. 6, 2019, entitled “ISOLATED MULTI-PORT RECHARGE SYSTEM”, the entire content of which is incorporated herein by reference.At present, maximum electric vehicle recharge rates are around 350 kW. Accordingly, for public recharge stations, where four or more ports are included, total demand can be in excess of 1 MW. As battery development continues, it is likely that power levels will go even higher. In order to support such power levels, medium voltage utility interface (three-phase voltage levels in excess of 1 kV) is desired in combination with a dedicated utility grade step-down transformer. With this design decision in place, it follows that the above utility transformer can be modified to provide individually isolated secondaries for each respective recharge port—with little added expense per unit power rating. No second transformer is required—thus reducing cost, size, and power loss.In , medium voltage utility power is applied via medium voltage utility feeder to utility disconnect and protection , which in turn transmits power to primary of utility transformer . Power received at secondary is then sent via protection and disconnect to three-phase rectifier . The DC output of rectifier is then applied to the input of buck regulator which reduces the voltage to the desired level for for application to recharge port . ...

A method for controlling a power distribution network includes receiving, via an electronic processor, a fault indication associated with a fault from a first isolation device of a plurality of isolation devices. The processor identifies a first subset of a plurality of phases associated with the fault indication and a second subset not associated with the fault indication. The processor sends a first open command to each member of a set of downstream isolation devices for each phase in the first subset. The processor identifies a plurality of tie-in isolation devices to be closed to restore power. Responsive to identifying a first potential loop configuration, for each of the plurality of tie-in devices, the processor sends a close command to the tie-in isolation device for each of the plurality of phases and sends a second open command to the associated downstream isolation device for each phase in the second subset. 1.
