20110316480 | SYSTEMS AND METHODS FOR DYNAMIC POWER COMPENSATION, SUCH AS DYNAMIC POWER COMPENSATION USING SYNCHROPHASORS - An electrical power generation system, such as a solar power inverter, can provide dynamic real-time power compensation, so as to mitigate the effects of voltage sags and swells (e.g., on a utility grid) and thereby provide voltage support functionality to a local grid. The electrical power generation system can do so by receiving first synchrophasor measurements that are taken at a point on the utility grid and transmitted to the electrical power generation system and by taking second synchrophasor measurements. The first and second synchrophasors indicate voltage magnitude and frequency of the alternating current (AC) at their respective measurement points. The electrical power generation system can compare the first synchrophasors with the second synchrophasors and based upon the comparison, vary the power factor of the power the electrical power generation system generates (e.g., by either supplying or absorbing reactive power). | 2011-12-29 |
20110316481 | METHOD FOR CONTROLLING SWITCHES OF SWITCHING ARMS, IN PARTICULAR IN VIEW OF CHARGING ACCUMULATION MEANS, AND CORRESPONDING CHARGING DEVICE - A method for charging accumulation means configured by an electric charging device is disclosed. The charging device includes switching arms respectively including a first switch and a second switch. The method involves ordering a predetermined number of first switches to close respectively for an associated closure time, and on each opening of a first switch that was previously closed, another first switch is ordered to close for an associated closure time, so that a constant number of first switches are closed at a same time. | 2011-12-29 |
