Abstract: A method of detecting an islanding operation of an electrical power generating system coupled to a power grid provided. The method includes monitoring a frequency that is indicative of an AC frequency on the power grid and monitoring reactive power on a coupling of the electrical power generating system to the power grid. The monitored frequency is processed to determine a rate of change of frequency, and the monitored reactive power is processed to determine a rate of change of reactive power. A detection parameter is determined from the determined rate of change of frequency and the determined rate of change of reactive power. An islanding operation of the electrical power generating system is detected if the detection parameter exceeds an islanding threshold value.

Abstract: A method and system of subsynchronous oscillations and interactions damping integrated in in a rotor converter based on an adaptive state feedback controller with two spinning vectors, and a Kalman filter whose parameters are optimized by minimizing maximum sensitivity under a constraint of positive damping for a plurality of sensible scenarios is provided. The damping signal generated by the damping module is applied either to a power proportional integer controller or to a current proportional integer controller.

Abstract: The disclosed apparatus may include (1) a ganged heatsink base that (A) absorbs heat dissipated by a plurality of electronic components that consume differing amounts of power and (B) includes a plurality of thermal regions dedicated to absorbing the heat dissipated by the plurality of electronic components and (2) at least one thermal isolation engine that (A) is incorporated into the ganged heatsink base, (B) separates the plurality of thermal regions from one another, and (C) localizes the heat dissipated by the plurality of electronic components by maintaining at least some of the heat dissipated by one of the electronic components within the thermal region that absorbed the at least some of the heat such that the at least some of the heat does not migrate to another thermal region included in the ganged heatsink base. Various other apparatuses, systems, and methods are also disclosed.

Abstract: A method, apparatus and computer program product for performing dynamic Voice Over Internet Protocol (VOIP) endpoint mapping is presented. At least one on net endpoint of a VOIP call is determined. An endpoint data structure is used to store, for each on net endpoint of the call, a key and at least one of an Internet Protocol (IP) address of the end point, a phone number associated with the endpoint, and/or a display name associated with the endpoint. The endpoint data structure is used to correlate call legs across a network. Heuristics of the VOIP call are determined, the heuristics including information relating to the main source call leg and the main destination call leg.
