Problems solved by technology

The existing periodic reporting of electrical characteristic quantities will cause loss of load fluctuation information, which cannot meet the requirements of subsequent fine-grained monitoring and high-dimensional analysis. Therefore, it is necessary to detect load fluctuation points and realize non-intrusive load sensing. The power consumption status of such equipment can provide users with detailed power consumption services

Abstract

The invention discloses a self-adaptive sampling method and system suitable for fluctuation signals, and belongs to the technical field of signal processing. The method comprises the steps of selecting characteristic quantity of a fluctuation signal according to an industrial and commercial user non-intervention load identification application scene, collecting the fluctuation signal and obtaining industrial and commercial user bus side waveform data, determining a calculation interval of the fluctuation signal according to the multi-dimensional characteristic quantity, and according to the calculation interval, calculating the multi-dimensional characteristic quantity of the industrial and commercial user bus side waveform data; performing smooth filtering processing and noise elimination processing on the multi-dimensional characteristic quantity, reserving a rising edge and a falling edge of the multi-dimensional characteristic quantity, and generating a multi-dimensional characteristic quantity sequence; and carrying out abnormal moving point judgment on the points of the multi-dimensional characteristic quantity sequence, reserving the judged abnormal moving points as sampling data, and carrying out adaptive sampling on the sampling data. According to the invention, the automation and effectiveness of load state judgment in a load identification algorithm are ensured.

Description

technical field [0001] The present invention relates to the technical field of signal processing, and more specifically, to an adaptive sampling method and system suitable for fluctuating signals. Background technique [0002] As an important part of power users, industrial and commercial users have a high proportion and diversified development trend of power load characteristics, which have an important impact on the upgrade, operation and maintenance of power grid sources, grids, loads and storage. [0003] At the same time, with the rapid development of the energy Internet, the real-time monitoring and big data collection methods of power grids for users are becoming more and more abundant. It is the basis and core of all related research. The existing periodic reporting of electrical characteristic quantities will cause loss of load fluctuation information, which cannot meet the requirements of subsequent fine-grained monitoring and high-dimensional analysis. Therefore,...
