配网终端广泛地分布在城市的角落.在已建成供电区域内,10kV线路大多没有同群铺设光缆,因此,在后期配电自动化建设过程中,往往会出现通信光缆无法到达的站点,采用全光纤覆盖建设配电通信网在已建成供电区域内很难做到。如果采用电力线载波或者无线通信作为一种补充的通信方式,完全可以做到全网覆盖。文章余绍了EPON、载波、无线三种通信技术在配电自动化通信系统建设中的应用,并对各种通信技术进行了分析比较.为配电自动化系统提供高效、可靠、全覆盖的通信解决方案。
Distribution terminals are widely distributed in the corners of the city.In the completed power supply area, most of the 10kV lines are not paved with optical fiber cables in the same group. Therefore, in the later period of distribution automation construction, there are often stations that can not be reached by communication optical cables. Optical fiber coverage of the distribution network construction has been completed within the power supply area is difficult to do. If you use power line carrier or wireless communications as a supplementary means of communication, you can do the whole network coverage. The paper introduces the application of EPON, carrier and wireless communication technologies in the construction of distribution automation communication system, and analyzes and compares various communication technologies to provide efficient, reliable and full coverage communication solution for distribution automation system Program.
