近年来,智能变电站的快速发展以及随之而来的信号、采集和传输等方面的根本变化,给变电站验收调试工作带来越来越多的挑战。从智能变电站与常规变电站二次系统调试的不同点出发,梳理了智能变电站二次系统调试过程中的关键技术要点及主要流程步骤,并形成了一套比较完整、通用的的智能变电站保护二次系统调试流程,同时结合天津市几座智能变电站现场调试过程中产生的技术问题,给出了解决办法和相应建议,对在建或拟建智能站的调试具有一定的推广意义。
In recent years, the rapid development of smart substations and the ensuing fundamental changes in signal, acquisition and transmission have brought more and more challenges to the commissioning and commissioning of substations. From the difference between the secondary system debugging of intelligent substation and conventional substation, the key technical points and main process steps in the process of secondary system commissioning of intelligent substation are sorted out, and a set of relatively complete and universal intelligent substation protection secondary System debugging process, combined with the technical problems arising from the field debugging of several smart substations in Tianjin, the solutions and corresponding suggestions are given, which has certain promotion significance for the commissioning of the intelligent station under construction or to be built.
