摘要
传统的单端测距算法需要考虑时间和行波波速两个因素,本文在原有的单端测距算法的基础上消去了行波波速参数,提出了一种不受行波波速影响的的单端测距新算法,与之前的单端行波测距算法相比该算法不受行波波速的影响的优点,而且计算方便、精确。经过ATP对该算法进行仿真验证,仿真结果证明了该算法的实用性。用该算法在超高压长距离输电线路测距误差可以保持在400m以内,更好的满足了电网的可靠运行要求。
The traditional single-ended locating algorithm needs to consider that the time and the traveling wave velocity,the algorithm of this paper has eliminated the traveling wave velocity on the foundation of original single-ended locating algorithm,a new single-ended locating algorithm which is not affected by traveling wave velocity is presented,the impact of traveling wave velocity is excluded comparing with the previous singleended fault location algorithm,this algorithm is convenient,accurate.The utility of this algorithm has been verified by the ATP simulation results.The location algorithm is with error no more than 400m in EHV.Traveling wave velocity long transmission lines,It can satisfy the requirement of power grids operation better.
