20150281278 | System For Securing Electric Power Grid Operations From Cyber-Attack - A system for securing electric power grid operations from cyber-attack, the system comprising a collection of security services distributed throughout a smart grid in two main categories of services; central security services and edge security services. | 10-01-2015 |
20110257924 | SELF-MONITORING AND COMMUNICATING TRANSFORMER - A self-monitoring transformer is disclosed. The transformer uses sensors embedded in the coils to determine the expected lifespan of the insulation, as well as other operating parameters, and communicates that information to an external system. | 10-20-2011 |
20100217548 | Fault Region Location System - A method for identifying an approximate fault location in a power transmission line comprises detecting first and second dominant frequencies in first and second recovering voltages resulting from the fault without using the velocity of either of the recovering voltages. | 08-26-2010 |
20090276173 | SYSTEM FOR REMEDYING ELECTRICAL POWER INSTABILITY - A system for real-time monitoring of synchrophasors from an electrical power system serving multiple geographic areas can control system instability, without preset parameters or thresholds, detects power flow between the generation sources. If a change in power flow of at least 5% over at time period of 1 second or less occurs and the response to the change in power flow is greater than the change in power flow a signal is generated for corrective action. | 11-05-2009 |
