20110139503 | CEMENTITIOUS FIBRE REINFORCED COMPOSITE CROSS ARM - A cross arm is provided, for use in a support structure for conductors within an electrical grid. The cross arm is made of a cementitious composite and has a rough āCā cross sectional shape. Pairs of the cross arms are attached to utility poles in a parallel position on opposite sides of the utility pole. Alternatively, a single cross arm may be attached to a utility pole. Embedded metal or glass fibre reinforced polymer bars extend along the length of the cross arms. | 06-16-2011 |
20090027067 | Method and system for real time identification of voltage stability via identification of weakest lines and buses contributing to power system collapse - A method of identifying voltage instability in a power system via identification of a weakest line and bus that contribute to the collapse of the system is provided. The method includes periodically calculating an extended line stability index for the transmission lines monitored in the power system; and using the extended line stability index to determine the distance of an operation state in the power system from a collapse point of the system caused by voltage instability. | 01-29-2009 |
20090027066 | Method and system of real-time estimation of transmission line parameters in on-line power flow calculations - A system and method for estimating parameters of transmission lines employing phasor measurement units is provided, wherein measurements are provided from the phasor measurement units relating to a transmission line. These measurements are filtered to remove invalid measurements. Using the remaining valid measurements, resistance, reactance and grounding admittance are calculated and estimated and checked for errors. | 01-29-2009 |
