Electric power is the important motive force of modern society. By reasonable planning great social and economic benefit can be attained. There is immediate significance to carry out the research of grid planning.In this article, load forecasting, power planning, power balance and power transformer capacity analysis are carried out on the basis of the present situation of Baotou grid according to the research on power consumption and the load level in previous years. Then several initial planning schemes of the Baotou grid are put up based on the main principles of grid planning. Subsequently, Essential electrical calculations are performed on the proposals. The one which is unqualified is eliminated. The remaining proposals are compared through risk assessment and investment budget.
