ABSTRACT

Power line communication (power line communication, PLC) technology is an important communication method widely used in power systems. The establishment of the power line channel model and the optimization of the power line carrier frequency are of great significance for the realization of high-speed data transmission on the power line. First, the basic theory of power line signal transmission is briefly introduced, and then the classification of the parameters required for modeling is carried out, and various power line channel modeling techniques are summarized. Introduce the development process of various modeling technologies, and analyze the advantages and disadvantages of various technologies. Finally, a power line carrier channel modeling method based on graph theory is proposed, and the feasibility of the method applied to medium voltage power line carrier communication in smart grid is analyzed. Summarizes the development history of intelligent diagnostic technology and the current research status at home and abroad, highlights its development and application in ECG diagnosis, describes various methods and diagnostic processes of ECG intelligent diagnosis, and discusses the development of ECG intelligent diagnosis technology and Outlook.
