基于新型站内引入光缆方案的研究与分析

Research and Analysis on New Scheme of Introducing Optical Cables

摘要:

随着电力通信的高速发展,对电力通信链路提出了更高的要求,进站光缆尤为重要。传统的站内引入光缆方式已无法满足新形势下的技术要求。重点探讨了基于新型站内引入光缆方案的研究与分析,全面解决传统模式下诸如进站OPGW多点接地、引入光缆与OPGW混盘等多项实际问题,为电力系统通信网络的安全稳定运行奠定基础,对电力系统光缆网架可靠运行具有重要意义。

Abstract:

With the continuous promotion of "the Belt and Road" construction, the export of power equipment has become an inevitable trend of industry development. However, the domestic control and protection equipment, especially the operation circuit of high-voltage circuit-breaker, is quite different from overseas products in device design, operation and maintenance habits. As a result, the domestic design concept is often not accepted by overseas counterparts. In order to improve the applicability of domestic operation circuit in overseas countries, a comparative study on the operation circuit of domestic and foreign high-voltage circuit-breakers is carried out from the aspects of device configuration, circuit design, operation and maintenance habits and coordination with primary equipment. The differences between domestic and foreign technical solutions are summarized. Based on the experiences of electrical secondary design of 卤800 kV Belo Mount II DC transmission project, the connotation of domestic and foreign technical differences is analyzed, and the key problems to be solved for overseas promotion of the relevant domestic equipment are pointed out.
