Problems solved by technology

[0004] However, the laying of pipes, especially the location of the wells at both ends of the pipes, is greatly restricted by the geographical environment. Therefore, the power grid construction department hopes to increase the laying length of the pipes (that is, the distance between the cable wells), and the laying length of the pipes is limited. Excessive increase will have a negative impact on the safe and reliable operation of cable equipment in the future, and the power grid operation unit hopes to limit the excessive increase in the laying length of the pipe

Description

technical field [0001] The invention relates to a power cable erection technology, in particular to a genetic algorithm-based data processing method for the laying length of cable pipes. Background technique [0002] With the rapid development of cities and continuous economic growth, the cable rate of urban power grids continues to increase. Taking Shanghai Power Grid as an example, the rate of underground cables in central urban areas has exceeded 80%. Power cables are gradually replacing overhead lines as an important part of advanced urban power grids. Pipeline laying is currently the most important cable laying method in Shanghai Power Grid. The application of cable pipes in Shanghai power grid can be traced back to 1933. So far, the total length of cable pipes in the Shanghai power grid has exceeded 800 kilometers, and a cable pipe network that can be used for 220kV cable lines has initially been formed. [0003] The pipe laying method has good reusability and relia...
