| 摘 要： | 电力工程上不但需要知道互感线路的零序集总参数, 有时还需要知道分布参数。通过对线路端电气量的同步测量,可以计算得到线路的集总参数,继而可以分别对互感部分和非互感部分求取线路的分布参数。笔者首先给出了输电线路分布参数模型和集总参数模型之间的转化公式;在此基础上,提出了互感线路分布参数在线测量方法,并通过仿真试验对所提出的方法进行了验证。

| Abstract: | Not only the zero-sequence lumped parameters of the transmission lines but also the distributed ones are needed to measure. Through synchronous measuring the voltage and current on the ends rameters can be calculated, considering the length of line with mutual inductance can of the lines, the lumped paand the distribute parameters and the length of the section be obtained. First, the distributed parameter model and the lumped parameter model of transmission line are given. Then, the conversion formulae between each other are also given. Based on them, this paper brings forward a method of zero-sequence distributed parameters measurement under operation. Finally, the simulating tests are carried out to prove this method. |
