Embedded Electrical Energy Measurement System Based on the M90E36A for Detecting High-Frequency Features in Household Appliances

In the state of the art of non-invasive load monitoring study, there are several proposals for the elaboration of datasets of electrical appliance consumption at different test frequencies, which allow the implementation of strategies and algorithms for energy monitoring. This paper presents an high-frequency electrical energy measurement system and digital signal processing to obtain non-conventional features that may be relevant for the study of energy disaggregation in real time. The system consists of the Atmel-DB board, based on the Atmel M90E36A integrated circuit, with channels for three-phase voltage and current measurement, a data acquisition board with an Arduino DUE for communication and a Raspberry Pi running the user interface and high frequency DSP. After a detailed description of the system, an application example is presented where high frequency signal processing is developed.
