Abstract

The invention discloses a non-intrusive load identification method and a non-intrusive load identification device. The non-intrusive load identification method comprises steps that electricity utilization behavior habits of users are counted to acquire first data; an electricity utilization load standard characteristic database is established; a voltage discrete signal and a current discrete signal sampled on a power supply entrance are acquired; the acquired voltage discrete signal and the acquired current discrete signal are preprocessed; load characteristics are calculated according to the transient voltages corresponding to various sampling points in the voltage discrete signal of the power supply entrance and the transient currents corresponding to the various sampling points in the current discrete signal of the power supply entrance; the load identification is carried out according to the load characteristics, and second data is acquired; the weighting of the first data and the second data is carried out, and the type of the load is identified. The technical problem of the prior art of the low accuracy of the load identification during non-intrusive load monitoring is solved.

Description

Technical field [0001] The present invention relates to the field of electric power, and in particular, to a non-intrusive load identification method and device. Background technique [0002] At present, the whole society is calling for energy conservation and emission reduction, and the construction of a conservation-oriented and ecological society. Electricity is becoming the main form of energy consumption, and as an important part of electric load, residential load is gradually increasing. Therefore, it is of great significance to analyze the user's situation, rationally arrange residential electricity consumption, and advocate low-carbon life, so as to achieve the goal of energy saving and emission reduction. Compared with lumped residential electricity information, residential electricity information accurate to a single electrical device and its type can bring multiple benefits to power companies, power users, related home appliance manufacturers, and the entire society. ...
