Method and system for creating electric power user electric appliance fingerprint database

摘要: The invention relates to a method and system for creating an electric power user appliance fingerprint database. the database comprises following steps of S1, selecting typical representative equipment carrying out electricity consumption data acquisition on equipment; S2, acquiring electrical characteristic information during operation equipment, namely, fingerprints; performing analysis calculation obtain quantities including active power, reactive factors by adopting FFT amplitudes phase angles harmonics; S3, associating obtained quantity characteristics extracted time with states corresponding recording storing well; S4, cleaningand checking recorded data, deleting bad complementing missing data. According system, creation is based second-level such as harmonics are integrated, so that identification performance improved, communication cost reduced.
