摘要
Abstract
The accurate fault location of distribution network over head transmission line is important measure to improve the safety operation of the electricnetwork.Whenever a fault occur since the transmissionline,the quick and exact fault location will not only reduce the manual work of the line inspectors,but also facilitate removal of fault and power restoration quickly for cutting down on economic loss due to the failure.In general the research addresses an important field that has both safety and economic implications.But in practical application the accuracy of system is decreased by the reasons of unsynchronized sampling and low sampling speed which cause the bigger location error. This thesis aims at designing the system schema of the high-speed dataacquisitiondevice for the fault locator, realizing high-speed, data acquisitionandlarge capacity data storage, analyzing the errorsource and difference between GPS system and oven controlled crystal oscillator ,providing the calibration algorithm of the second pulse of GPS system,anddeveloping the power supply for fault locator which can provide the referencefor finding fault time,judging fault type and calculating fault point distance.关键词
