【摘要】 随着社会的发展,用户对用电质量和可靠性的要求越来越高,电网故障对社会生活造成的影响愈来愈大,经济损失难以估计。因此快速准确找出故障点,对电力系统安全可靠地运行非常重要。配电网单相接地故障定位一直是人们关注和研究的焦点,但至今尚没有一种实用有效的配电网故障定位方法。本文通过对现有故障定位方法的研究,提出一种适合配电线路的,在系统发生单相接地故障时,能快速、准确进行故障定位的方法一一G型行波定位方法,并利用ATP软件进行仿真分析,从而验证了该方法的有效性。更多还原

【Abstract】 With the development of our society, the consumers of electricity quality and reliability have become increasingly demanding. The fault of power line impacts on social life, more and more, and it is difficult to estimate economic losses. Therefore quickly and accurately identify the faulty point is very important to the power system for the safe and reliable operation. The single-phase grounded fault location is the focus which researchers pay attention to the distribution network. And so far, there is not a kind of practical and effective fault location method to distribution line. This paper proposes a fault location method for distribution line --G-Traveling wave fault location by researching various methods of fault location. It can fast and accurately fault location when system occur single-phase grounded fault. Through analyze by software ATP simulation and verifies the practical of the method.更多还原
