Abstract：This paper introduces the recent thedevelopment of the power line communication. At the same time, the defects ormerits of the power line communication are included in this paper. Simplyintroduced the concept and characteristics of intelligent power grid. It mainlydiscusses the principles of the spread spectrum communication and orthogonal frequencydivision multiplexing and the abilities of their withstanding noise andattenuation. Meanwhile a lot of examples which adopt these technologies arelisted in this paper. In the end, it describes the development and application ofthe power line
