The invention discloses an electric power information accurate sending and receiving method and device. The method comprises the following steps of S1, simplifying a line and making the line be formedby a main line unit, a subsection unit, a branch unit, a village street/cell unit, and a special change user access unit, and realizing line model construction; S2, storing a line structure through an adjacent matrix mode; S3, when a message sending position point is selected, calculating and acquiring the user range of message receiving through a matrix transformation mode; S4, forming a user power utilization position binding module; S5, forming a power utilization position optimization selection module; S6, forming an information feedback module and S7, forming an association position optimization module. Based on the information issuing and receiving method of the invention, electric power information can be accurately and rapidly sent, the timely interaction of the electric power information is realized, and the problems of information barriers, information asymmetry and the like between a current electric power company and a user are solved.
