Isolated operation detection device

Номер: US20120007436A1
Принадлежит: Fuji Electric Co Ltd

With a method whereby reactive power is changed from a fluctuating output to a constant output by a frequency rise or fall monitor circuit stage level being exceeded, and an isolated operation is detected, a problem occurs with a small scale grid in that, as the frequency is liable to fluctuate due to a load fluctuation, there is liable to be a false detection of an isolated operation. In contrast, an abnormal frequency stage detection can be performed such that the frequency at a point when the rising edge of a reactive power fluctuation is detected, and the frequency at a point when the falling edge is detected, are detected sequentially, and an abnormal frequency stage detection is recognized when the order of the difference between the current detection value and the previous detection value is “increase”, “decrease”, “increase”.

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.
