20150066402 | Power System State Estimation Using A Two-Level Solution - A power system grid is decomposed into several parts and decomposed state estimation steps are executed separately, on each part, using coordinated feedback regarding a boundary state. The achieved solution is the same that would be achieved with a simultaneous state estimation approach. With the disclosed approach, the state estimation problem can be distributed among decomposed estimation operations for each subsystem and a coordinating operation that yields the complete state estimate. The approach is particularly suited for estimating the state of power systems that are naturally decomposed into separate subsystems, such as separate AC and HVDC systems, and/or into separate transmission and distribution systems. | 03-05-2015 |

20100066381 | APPARATUS AND METHOD FOR ADAPTIVE FAULT DETECTION IN MV DISTRIBUTION CIRCUITS - A method and a protective device operable to perform the method are provided, wherein the method is for detecting and analyzing faults in a first cable and one or more other cables, which convey power in a three phase feeder system. Current magnitude in the first cable is compared to a threshold level. If the current magnitude exceeds the threshold level, the duration of the condition is measured. If the duration falls within a predetermined duration range, a predetermined time interval is allowed to pass and then a determination is made whether a fault is detected in the one or more other cables. If a fault is not detected in the one or more other cables, then a determination is made that a single phase fault has occurred in the feeder system. | 03-18-2010 |
