  • Patent number: 10855107
    Abstract: A system and method for determining a reliability line rating for a transmission line is disclosed. In response to a line clearance measurement and a line temperature measurement received from a transmission line monitor coupled to a transmission line, the system generates a temperature-clearance model for the transmission line based on the received line clearance measurement and line temperature measurement. The system generates a plurality of past dynamic line ratings and determines a scaling factor based on the plurality of past dynamic line ratings. The system then generates a dynamic line rating for an interval of time in the future and scales the dynamic line rating in response to the scaling factor to obtain a reliability line rating for the interval.

  • Patent number: 10826428
    Abstract: To ensure photovoltaic (PV) panels at a PV plant constantly operate in an ideal state, an unsupervised system and method of intelligent performance evaluation and data-driven fault detection is used. The system and method enables engineers to check PV panels in time and implement timely maintenance. Monitored data are classified into three subsets: ideal period A, transition period S, and downturn period B. Based on A and B data, two regression prediction models are built which are tree-based and fit the non-continuous PV data well. Real-time measured power is compared with upper and lower reference baselines derived from the two predictive models, respectively. Using threshold ranges, the system and method achieves the instantaneous performance monitoring of PV power generation, and provides failure identification and operation and maintenance (O&M) suggestions to engineers.

  • Patent number: 10825317
    Abstract: The disclosure is related to a method for avoiding misjudgment when detecting a human fall, and an apparatus thereof. When the apparatus worn on a person generates a collision signal, it determines if the apparatus was in a proper status in the past period of time before the collision according to the acceleration data. The apparatus was in the proper status if a specific axial direction of an accelerometer of the apparatus is substantially parallel with the direction of gravity, and the method goes on detecting the human fall; otherwise, the process is terminated. The acceleration data before and after the collision is compared with fall conditions set by a fall detection program. A fall event is determined if the acceleration data meets the fall conditions.

  • Patent number: 10808521
    Abstract: This disclosure describes a method of assessing fractures in an underground formation using temperature profile measured by a DTS. The fractures can be identified by a temperature profile established by the feedback signals obtained from the DTS, but the DTS measurements are made at least 36 hours after a stage is fractured and during shut-in, thus allow crossflow and other noise sources to abate. Further, the size of the temperature differential is indicative of fracture spacing or density, not volume of fluid flow as thought in the prior art. Thus, these methods can be used to optimize the next stage or next well in a fracturing program.

  • Patent number: 10809313
    Abstract: A central idea of techniques herein is that by means of modulation or variation of the supply signal of a Hall sensor, the useful signal portion in the resulting sensor output signal can be separated from the offset portion during operation of the Hall sensor, with no previous calibration or previous serial tests. That course of the sensor output signal resulting from the modulation or variation of the supply signal can then be evaluated or decomposed relative to the components which can be attributed to the offset portion and the useful signal portion. Thus, the offset portion in the sensor output signal can be determined with no (or a negligibly small) external magnetic field applied or with an external magnetic field applied, in case the external magnetic field is constant within a tolerance range while determining the offset portion.
