改进行波雷电定位法的应用研究

Application Research of the Improve of Lightning Strikes Location Method of Traveling Wave

应用一种改进的双端行波输电线路雷击定位方法,用系统中线路进行仿真分析加以验证,证明其实用价值。此方法不需要事先确定波速,消除了波速的不确定性所带来的误差,定位精度高于传统双端行波定位法。

The paper combined with a lightning strikes detection and location method based on an improved double -terminal traveling wave theory, the analysis and simulation of an existing transmission llne in power system shows that this new method is correct,and it provide the basis of engineering application. The method doesnt need to determine the velocity of the traveling wave before measurement, so the measurement error caused by the uncertainty of the wave velocity can be avoid. Compared with the traditional traveling wave location method, this method is more efficient and accurate for lightning location.
