Power based event detection for electrical appliances

Abstract

Abstract.Appliance specific energy monitoring is perceived as a prerequisite for reducing energy usage in households.In this paper, a non intrusive monitoring method is introduced, and a power identification algorithm based on transient detection is introduced. Then the simulation experiment is carried out by using different analysis methods. In order to improve the accuracy of the opening and closing of smart grid and adapt to the development trend of recognition of household appliances, based on this algorithm is put forward in the circuit current, power and other parameters combined with information, if the average power of several cycles of adjacent difference changes different from the baseline, a fixed threshold is exceeded. This event will be recorded, and based on the MATLAB platform, the household appliances simulation, test data, the algorithm was verified, the results show that the proposed method to detect electric power has a good recognition results.
