NON-INTRUSIVE ONLINE REAL-TIME POWER LOAD IDENTIFICATION METHOD AND IDENTIFICATION SYSTEM

摘要

Provided are a non-intrusive online real-time power load identification method and an identification system. The identification method comprises the following steps: A. acquiring a real-time power signal; B. performing non-intrusive load identification and analysis; and C. feeding back a result. The identification system comprises at least one terminal (4) of an embedded device connected to a residence-side power distribution box (1). The terminal (4) of the embedded device is connected to a cloud terminal (2). The cloud terminal (2) is connected to a backend server (3). The backend server (2) is connected to a data storage (6) and can transmit an analysis result to a terminal device (7) corresponding to the residence-side power distribution box (1). The identification method and the identification system can reduce costs for a residence-side user and perform training without requiring a large number of labeled samples, is sensitive to a low-load electrical device, can solve a problem of electric energy fluctuation, and ensures accuracy of load identification. The invention can provide a household with a comprehensive energy solution. The efficient algorithm of the invention can achieve online and real-time effects.
