Abstract

The invention discloses an asynchronous load acquisition modification method for partial electricity utilization, which relates to the technical field of electric power, and aims at solving the technical problem of reducing the acquisition time error of asynchronous data acquisition. The method comprises the following steps of: obtaining an electricity utilization wire-outgoing load set and electricity utilization load data of an energy consumption monitoring system, and dividing the obtained electricity utilization load data into two types at first; then calculating a current difference and an active power difference, and then calculating a modification factor; then performing corresponding modification on the three-phase current, active power and reactive power of each wire-outgoing load by virtue of the modification factor. The method provided by the invention is capable of improving the accuracy of an energy consumption monitoring analysis result.
