Research on power gathering problem and power transmission strategy in Guangxi coastal area

Abstract

 the construction of power supply is affected by resource conditions, plant construction conditions, load distribution and power grid structure, which shows a trend of more and more centralized distribution.If the power supply is too concentrated, the short circuit current will be increased, the risk of system security and stability will be increased, and the regional power transmission channel will be insufficient.The key to solve these problems is to find a suitable power transmission strategy.On the basis of fully summarizing the typical structure of domestic power grid, this paper puts forward the construction strategy of group transmission and layered transmission, and applies it to the construction of clean energy transmission grid in Guangxi coastal areas.
