Abstract: An example method for detecting and mitigating attacks on electric power substations comprises detecting a command to open or close a circuit breaker in the electric power substation. A modified extended substation model for the electric power substation is generated, based on the detected command and based on measurements in substation, where the modified extended substation model is a power flow model for the substation and for one or more directly connected neighboring substations. A power flow analysis is performed, using the modified extended substation model, to generate a predicted voltage for each of a plurality of nodes in the substation and in the one or more directly connected neighboring substations. Each predicted voltage is compared to a corresponding allowable voltage range, and execution of the command is blocked in response to determining that one or more of the voltages is outside the corresponding allowable voltage range.

The DC-DC power converters further include a control circuit configured to control the switching converter subcircuits so that corresponding switching semiconductors in each of the switching converter subcircuits are switched in an interleaved manner. In some embodiments, each of the switching converter subcircuits is a three-level, neutral-point-clamped, four-quadrant DC-DC converter circuit. In other embodiments, each of the switching converter subcircuits is a three-level, neutral-point-clamped, two-quadrant DC-DC converter circuit. In any of these embodiments, a filter capacitor may be connected between across a pair of output terminals at the output sides of the switching converter subcircuits.

Abstract: A cross-direction feedback controller, profiler system and actuator setpoint controller are provided in communication with a plurality of actuators in a machine of a web-forming process, and with a local region detector that determines an actual profile response of a product of the web-forming process in response to consecutively bumping each of the actuators. A relationship between generated profile response data and an actuator setpoint change in the generated profile response data is represent by a profile-to-actuator general interaction matrix, which is expanded into linear equations that describe impacts of bumped actuators on different profile points of generated profile response data. The linear equations are rearranged into a bump-magnitude matrix as a function of a desired response model vector. A least-square solution is found for the bump-magnitude matrix, convolved with a window function and then optimized to minimize error between an actual and a modeled profile response.

Abstract: Waveform information is transmitted from the ends of a protection zone by first compressing the information using a lossy compression technique such as wavelets and then compressing the lossy compressed waveform information using a loss-less compression technique such as the Burrows-Wheeler transform. Status information is transmitted from the ends of the protection zone by compressing that information using the loss-less technique. The time for transmission can be less than, equal to or greater than the time for one cycle of the power line frequency.

Abstract: This invention relates to a three-stream atomizing nozzle for use with a rewet shower. The nozzle has an air stream divider that separates the atomizing air from the source into three streams. The first stream is a straight air stream staying closest to and around the atomized water jet. The second stream is a swirl running around the first straight stream. The third stream is also a straight stream that wraps around the first straight stream and the second swirl. The nozzle also has a mixing chamber in which the three air streams are mixed together for the atomizing purpose. The nozzle can from the combination of the three air streams produce fine water droplets that are suitable for a paper rewet shower and more importantly creates a tailorable water mass profile. The mass profile can be tailored into a shape that is close to a square shape which is ideal for rewet showers as a square profile creates minimal coupling between adjacent zones.
