Description

technical field [0001] The invention relates to the technical field of power system analysis, in particular to a neural network-based load characteristic analysis system and method. Background technique [0002] Load characteristics are the unique electrical characteristics of electrical equipment when they consume electricity. Different electrical equipment has large or small differences in load characteristics when they are working. For example, different equipment consumes different active and reactive power, and the current of linear loads and nonlinear loads The curve and harmonic content are different, and the V-I characteristics of electric loads and non-electric loads are different. [0003] With the continuous construction and development of smart communities and industrial electricity consumption in my country, a large amount of residential electricity consumption data has been accumulated. In the face of scattered massive data, it is necessary to mine and study t...
