复合阻抗在OPGW中的应用研究

随着通信技术的发展，利用在电力系统输电线路沿线架设OPGW进行数据传输与通信在国内外已得到了广泛的应用。为了保证OPGW不受系统运行方式和故障的影响而正常运行，文章采取在OPGW上装设复合阻抗的方法，使OPGW中的感应电压和电流在其允许范围之内，保证其能够长期正常工作。同时还通过EMTP仿真程序，对这一方法进行了有效的验证，结果表明该方法确实能解决一些实际问题。

Research on the composite impedance application in OPGW

With the progress of communication technology, it is widely used now to transmit data and message through OPGW in the world, which is spanned along the transmission line. To avoid the influence of the running ways and faults of power system on OPGW and to ensure its regular running, a measure that install composite impedance in OPGW to keep the inductive voltage and current of OPGW within the allowable range is presented in this article. The author validates its effectiveness by using simulation program EMTP (Electromagnetic Transient Program), and the results show that this way can resolve some practical problems.
