莲花电站地形复杂，高差较大，地质为花岗岩，土壤电阻率高，使用普通避雷针做直击雷保护不仅有一定困难，而且可靠性差。为此，在认真分析拒引结合防雷装置防雷机理的基础上，进行了模拟实验，证明了采用防止与疏导相结合的防雷装置是可靠的，为首次应用于莲花电站提供了设计依据。
Lianhua Power Station topography is complex, large elevation, geological granite, high soil resistivity, the use of ordinary lightning rod to do direct lightning protection not only have some difficulties, but also poor reliability. Therefore, on the basis of carefully analyzing the lightning protection mechanism of the lightning protection device, the simulation experiment is carried out, and it is proved that the lightning protection device combined with the prevention and guidance is reliable and provides the design basis for the first time applied to the Lianhua Power Plant .
