【摘要】 配电网故障测距一直是电力系统中的难点,为找到切实可行的解决方案,针对配电网不同于高压输电线路的特点,诸如混合线路、线路分支多、线路短等,对现有的各种测距方法进行了归纳总结。结合配电网故障测距的新动向,对混合线路配电网的未来测距方向进行了初步探讨,但该解决方向的可行性和实用性还需要更多的理论和实践支持。更多还原

【Abstract】 Fault location for distribution networks is still a difficult problem to be solved. To find a practical and feasible solution, existing fault location methods are induced and summarized according to the specialty of distribution networks different from high voltage transmission lines, such as hybrid lines in which overhead lines and power cables coexist, highly branched lines, short line length, etc. Considering new development trend of fault location for distribution networks, the future development of fault location for hybrid lines is preliminarily researched, and the possible solution is proposed, of course, the feasibility and practicality of the proposed solution need more supports from theory and practice.更多还原
