【摘要】 近年来双端电气量故障定位算法成为国内外研究的重点。但是,线路参数和长度的变化对于故障定位精度的影响却迟迟没有很好地解决。如何把因线路参数和线路长度的变化所引起的误差动态地加以修正是目前亟待解决的问题之一。作者根据线路参数和线路长度之间的相互联系及其映射关系,提出了一种新的参数修正方法。通过仿真比较表明,该方法有效地解决了长度和参数变化所引起的误差问题。更多还原

【Abstract】 In recent years the research on two terminal fault location algorithms became the major research emphasis home and abroad. The problem that the influence of variations in length and parameters of transmission line on fault location accuracy is still not well revealed, therefore how to dynamically correct the errors caused by the variation in length and parameters of transmission line is one of the urgent problems to be solved. According to the interrelationship between the parameters and length of the transmission line and their mapping a new parameter correcting method is proposed. The results of simulation show that the proposed method can effectively correct the errors caused by the length and parameter variations.更多还原
