Abstract

The embodiment of the invention discloses a power signal filtering method and system utilizing an energy scale. The method comprises the following steps: step 101, acquiring a signal sequence S acquired according to a time sequence; step 102, solving an energy scale coefficient sequence; step 103, solving an edge energy scale coefficient; step 104, solving a direction energy scale coefficient; step 105, solving a direction scale threshold value; step 106, solving a high-density energy scale coefficient; and step 107, solving a signal sequence after noise filtering.

Description

Technical field [0001] The present invention relates to the field of electric power, in particular to a filtering method and system for power signals. Background technique [0002] With the development of smart grid, the analysis of household electricity load becomes more and more important. Through the analysis of electricity load, household users can obtain the electricity consumption information of each electrical appliance in time, as well as the refined list of electricity bills; the electric power department can obtain more detailed user electricity information, and can improve the accuracy of electricity load forecasting. Provide a basis for overall planning for the power sector. At the same time, the electricity consumption information of each electrical appliance can be used to know the user's electricity consumption behavior, which has guiding significance for household energy consumption assessment and energy saving strategy research. [0003] Current electricity load ...
