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 series-capacitance compensated shielding circuit is located physically adjacent and parallel to a polyphase power transmission line for the purpose of partially cancelling the electromagnetic fields created by current flow through the transmission line. The shielding circuit forms a loop circuit around substantially the entire transmission line or a portion thereof, and is positioned such that a current is induced therein by the magnetic field produced by the alternating currents in the transmission line. Such induced current is tuned by the series capacitance to produce an optimized cancelling magnetic field, thus reducing the net electromagnetic fields created by the power lines along a right-of-way.

An apparatus for anti-islanding protection of a distributed generation with respect to a feeder connected to an electrical grid is disclosed. The apparatus includes a sensor adapted to generate a voltage signal representative of an output voltage and/or a current signal representative of an output current at the distributed generation, and a controller responsive to the signals from the sensor. The controller is productive of a control signal directed to the distributed generation to drive an operating characteristic of the distributed generation out of a nominal range in response to the electrical grid being disconnected from the feeder.
