This paper describes in detail the actual situation of the social and economic development of City A, and analyzes the current situation of City A's power grid in detail, focusing on the actual problems existing in the high-voltage distribution network of City A. And the meaning, tasks and methods of power grid planning, combined with the high-voltage distribution network planning of City A, are analyzed with examples, and the basic planning ideas are clarified. Grid planning focuses on the overall study of the grid, starting with the transformation and strengthening of the existing network, solving the weak links in the network structure, and expanding the power supply capacity of the network. The article analyzes the current network status of City A in detail with sufficient data, according to the growth of power demand and the trend of urban development, and refers to the technical principles of construction and transformation of the high-voltage distribution network in City A, and combines the actual conditions and new conditions of City A In order to increase the load, the high-voltage distribution network planning and implementation plan has been formulated in detail, which provides a reference for the development of the high-voltage distribution network in City A. The new grid structure avoids the shortcomings of the original grid in the area, can meet the needs of the current and future load development in the area, can transfer the load in the event of a failure, ensure the reliability of power supply, and gradually strengthen the automation level of the grid , Realize comprehensive automation.
