The energy and power industry is undergoing a period of rapid reformation and development

and the third industrial revolution featured by new energy technologies and Internet technologies is emerging. Under the background of a new round of energy revolution

State Grid Corporation of China proposed the strategic goal of ’ three-type and two-network’’

and the construction of ubiquitous power internet of things（IoT） opens up a new path for safer operation

leaner management

more accurate investment

more accurate service and better quality of power grid. Power distribution internet of things（PD-IoT） is the application embodiment of ubiquitous power IoT in the field of distribution. It is a new type of power network operation that is generated by the deep integration of traditional power industry technology and IoT technology. This paper expounds the construction concept

implementation characteristics and overall architecture of PD-IoT

discusses the key technologies involved in each layer of the ’’cloud channel edge terminal’’ of PD-IoT. Then

this paper analyzes the application effect of PD-IoT in different business aspects

and gives a summarization and prospect on the next step of the construction and development.
