Abstract：Based on the model of Logistic function based on S curve, the formation of the power grid development stage division theory system, and the characteristics of each stage of the development of power grid is described, and then through the Marquardt iteration method to estimate the parameters of S curve regression model, combined with the developed national grid development verified S curve model of power grid development stages based on the the domestic Z power grid development as an example, calculated the approximate time of power grid development, guide the key to power grid planning and construction.
