Design of Non-intrusive Load Monitoring System

In order to promote the high-quality development of electricity market and provide users with wonderful power consumption experience, it is necessary to deeply analyze the power consumption behavior and characteristics of users, but the traditional power monitoring can no longer meet this requirement. Therefore, a non-intrusive load monitoring system is designed in this paper based on the non-contact high-frequency synchronous power data acquisition device. A non-intrusive online load monitoring system is designed by building offline the load feature database and training the model. The data sent to the server by the power data acquisition device are sequentially tested for events, extracted for features and input to the model for load identification. The experimental results show that the load identification accuracy of this system is high, which can meet the needs of real life and engineering.
