Abstract

The embodiment of the present invention discloses a power signal filtering method and system utilizing noise and jitter properties. The method includes: Step 101 to obtain the signal sequence S collected in time order; Step 102 to obtain the noise and jitter scale factor; Step 103 to obtain Noise jitter translation factor; Step 104 asks for N noise jitter factors; Step 105 asks for filtering threshold; Step 106 asks for N 2 filter weights; Step 107 obtains the signal sequence after filtering the noise.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and system for filtering 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 a timely manner, as well as a detailed list of electricity charges; the power department can obtain more detailed user electricity consumption information, and can improve the accuracy of electricity load forecasting, Provide a basis for overall planning for the power sector. At the same time, using the electricity consumption information of each appliance, the user's electricity consumption behavior can be known, which is of guiding significance for household energy consumption assessment and research on energy-saving strategies. [0003] At present, the...
