Multi-energy disturbances might occur in the process of energy production
dispatch and use owing to the integration of electrical energy
natural gas
thermal energy
and so on. Traditional disturbance detection based on off-line data can hardly meet the real-time requirements of the energy internet. Data stream technology can be used to detect multi-energy disturbance signals on line. By proceeding from the interaction between energy and information
the energy internet multi-energy disturbance problem is analyzed
and mathematical models of different disturbance signals are developed. These disturbance signals are decomposed using wavelet transform and a signal data stream processing model of disturbance signals based on a sliding window with a synoptic data structure is built first. Secondly
for the purpose of rapid updating of the outline structure
the wavelet tree updating algorithm is improved. As a result the extraction of perturbation signal features is optimized and the decision tree algorithm is used to classify these signal features. Finally
the data stream processing model built in this article is applied to the identification of power quality disturbance and gas quality disturbance to verify the validity of the data stream model.
