The invention discloses a load characteristic analysis method for a power distribution network. Load characteristic analysis and investigation are basis of power system planning, and is necessary means for understanding and predicting users and markets within the scope of jurisdiction. A resident load and an industrial and commercial load are important parts of a city load; and an investigation on the resident load and the industrial and commercial load is of great significance to load prediction, power supply scheme establishment, urban power network planning, economical operation of the power network and power marketing. According to the method disclosed by the invention, analytic statistics is carried out on the loads in the 10kV power distribution network; daily load characteristics, influence factors and change rules of various loads are searched; a typical day curve is formed; a basis can be provided for work of operation mode arrangement, reasonable planning and the like of the power distribution network; and a support is provided for continuous improvement of advanced applications of the power distribution network.
