    摘要： A system for distributing electrical current to a plurality of loads includes a first sensor coupled to an input of a protection zone for measuring a first current entering the protection zone, wherein the protection zone includes at least a portion of an electrical distribution feeder. The system also includes a second sensor coupled to an output of the protection zone for measuring a second current exiting the protection zone, and a processor coupled to the first sensor and to the second sensor. The processor is programmed to receive measurements representative of the first current and the second current, and calculate a reactive current differential of the protection zone based on the first current and the second current. The processor is also programmed to compare the reactive current differential with a fault threshold, and generate an error notification if the reactive current differential is greater than the fault threshold.

    摘要： Systems and methods for dewatering mine tailings. The systems and methods include distributing a slurry of high permeability material on a sloped surface to define a high permeability layer and subsequently distributing a slurry of low permeability mine tailings on the high permeability layer to define a low permeability layer that is vertically above and in contact with the high permeability layer. The sloped surface defines a non-zero surface grade, and natural slopes of both the slurry of high permeability material and the slurry of low permeability mine tailings are within a threshold grade difference of the surface grade. In some embodiments, the systems and methods may include augmenting the slurry of high permeability material and/or augmenting the slurry of low permeability mine tailings to adjust the natural slope thereof.

    摘要： A method of load forecasting for a present day includes obtaining past observed load values of at least three earlier days and identifying a relationship between the present day's load forecast and the past observed load values including unknown weights associated with the past observed load values. The values of unknown weights are determined by comparing at least one previous day's load forecast with the observed load value of the at least one previous day. The determined weight values are then used in the relationship between the present day's load forecast and the past observed load values to forecast the present day's load.
