Embodiment Construction

[0043] Shanwei City is located on the southeast coast of Guangdong Province and borders the South China Sea in the south. It is the hardest hit area by typhoons. The following selects the planning grid scheme of Shanwei power grid in a certain year, and adopts the method for constructing the grid grid for wind protection and security in coastal areas based on the graph theory algorithm to conduct research and analysis on the grid in this area. Other features, objects and advantages of the present invention can also be seen from the description of the embodiment and the accompanying drawings.

[0044] like figure 1 As shown, using the present invention to carry out research and analysis includes the following steps:

[0045] S1 obtains the grid topology diagram of Shanwei's planned power grid from Shanwei Power Supply Bureau. Figure 4 It includes the stations (substations, power plants) of 110kV and above, the starting point and end point of the 110kV and above lines, the le...

Abstract

Disclosed is a coastal area wind prevention security power grid frame construction method based on a graph theory algorithm. The coastal area wind prevention security power grid frame construction method based on the graph theory algorithm includes: using a graph theory path search algorithm to identify power grid frame topology structures of 220KV and above for current and planned power grids, obtaining important degrees of each station and each circuit in topology for normal running and rapid power restoration, and forming a core backbone grid frame of 220V and above in a regional power grid; simultaneously, combing an important user power supply route, selecting a key station and a key circuit which supply power for important users according to a distribution situation and differentiation of the important users, and forming an important user security power supply radiation type fishbone grid frame; then, selecting a contact circuit of a center urban area and an outer area according to grid frame security requirements; finally, organically combining the core backbone grid frame, the radiation type fishbone grid frame and the contact circuit of the center urban area and the outer area so as to construct a coastal area wind prevention security power grid frame. The coastal area wind prevention security power grid frame construction method based on the graph theory algorithm can effectively improve the ability of the regional power grid of withstanding intrusion of natural hazards of typhoons and the like, guaranteeing the important users and supplying power for areas.

Description

technical field [0001] The invention relates to a method for constructing a grid frame for wind protection and safety in coastal areas, in particular to a method for constructing a grid frame for wind protection and safety in coastal areas based on a graph theory algorithm. Background technique [0002] The southern coastal provinces of China, such as Guangdong, are located in the South subtropical zone and are located in the main route of tropical cyclones landing on the Asian continent in the Northwest Pacific. The activities of tropical cyclones are extremely frequent. The landfall caused major damage to the power grid in the coastal areas of Guangdong. [0003] The measures taken by the power grid in coastal areas to resist typhoons include reasonable arrangement of operation modes, reinforcement of tower bases, installation of windproof and tensile cables, and configuration of emergency mobile power generation equipment. In the planning and design stage, the annual ave...
