摘要
随着智能变电站技术的日益成熟,早期试点投运的智能站在日常运行中,逐渐暴露出一些影响电网安全运行的问题。本文主要根据合并单元的特点,以省内前期投运且近期刚刚完成施工的500kV G智能变电站为例,按照各个电压等级,详细梳理和探讨了合并单元在升级改造中所涉及的关键技术、危险点等问题,介绍了切实可行的优化施工方案。该改造工程的顺利完成,验证了该施工方案的现场适用性,积累了相关工作经验,更对今后其他智能站的类似施工工程具有很好的参考性和借鉴作用。
With smart substation technology becoming more mature, the early pilot of samart substation in daily operation gradually exposed some issues which affecting the safe operation of the power grid. This paper mainly according to the characteristics of the merging unit and the different voltage class, take the 500 kV G smart substation in the province which have been putted into operation early and completed construction recently, introduces the practical and feasible optimizing construction scheme in detail, and discusses the key technologies and dangerous points involved in this scheme. The successful accomplishment of renovation project, not only validated the industrial applicability of the optimizing construction scheme, accumulated the related working experience, and more have a valuable reference to the other similar construction project of smart substation in the future.
