Electric energy meter electric energy quality detection method, system and device

Abstract

The invention discloses an electric energy meter electric energy quality detection method, system and device, and the method comprises the following steps: obtaining voltage waveform data, and recording electric energy quality classification conditions on the voltage waveform data; preprocessing the voltage waveform data, and dividing the voltage waveform data into a training set and a test set; training a deep belief network model by using the training set data; and inputting the test set into the trained deep belief network model to carry out precision test on the deep belief network model,and inputting the real-time voltage waveform data into the deep belief network model to obtain a real-time power quality classification situation. According to the method, the deep learning theory isapplied to electric energy meter electric energy quality monitoring, the voltage characteristics when the electric energy quality problem occurs are automatically learned and extracted through the deep belief network, the electric energy quality classification condition of the electric energy meter user side is accurately and rapidly monitored, complex operation of manual characteristic extractionis avoided, and the calculation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric energy quality detection, in particular to a method, system and equipment for electric energy quality detection of an electric energy meter. Background technique [0002] At present, with the rapid development of renewable energy such as wind power photovoltaics and the large-scale use of new loads such as electric vehicles, the frequency of power quality problems such as harmonics, voltage fluctuations and flicker is increasing, which seriously affects the normal operation of precision equipment. Therefore, it is urgent to monitor and identify the power quality on the user side, provide users with real-time power quality information, and improve the user's power quality and consumption experience. However, at present, the energy meters in our country only have a single harmonic monitoring function, and do not have a complete power quality monitoring and identification function. On the other han...
