Study on Network Frame Models of Urban Target Power Grid
-
Abstract
A reasonable and scientific vision of the urban power grid structure can ensure the safe operation of power grids and long-term stability. According to the characteristics of power supply, network connection and power distribution, this paper combs and analyzes the network frame models of domestic and foreign target power grid, and illustrates double-loop network frame model and Grouped subarea division model. The paper also puts forward the advantages and disadvantages of various types of network models. Then it focuses on the analysis of typical large city grid in China, such as Beijing and Shanghai, and analyzes the grid structure, operation experience and design principles of Beijing and Shanghai power grid, especially operation mode of 500 kV terminal substations, which provides references for the development of other cities.
