Survey of fault location research for HVDC transmission lines
摘要
Abstract
The HVDC line fault location methods at home and abroad are surveyed in this paper. Firstly, the disadvantage of the existing fault location techniques of HVDC transmission line is analyzed, and it is point out that the engineering applications of fault location of HVDC transmission line are based on traveling wave principle at present. The fault location principle is relatively simple, requiring high sampling rate, and its tolerance ability of high resistance is not sufficient. Making use of the dividing method of fault location principle of AC transmission line, the fault location principle of HVDC transmission line is classified and studied. The HVDC transmission line fault location methods are divided into traveling wave method and fault analysis method. Furthermore, the advantages and disadvantages of each fault location principles of HVDC transmission line are reviewed respectively and it is pointed out that fault analysis method has broad application prospects. Finally, several important problems which need to be further studied are proposed.关键词
