110kV高港变数字化改造

Implementation of Digitized Transformation in Gaogang 110 kV Substation

就目前数字化变电站改造实现形式的灵活和多变,介绍了在江苏电网中进行数字化改造的实现方案,并针对改造中遇到的采样信号传输、合并单元配置和采样值同步、数字化电压信号的并列与切换实现问题进行了详细阐述,给出了应用于变电站改造的解决方案。

Based on the flexibility and variability of implementation forms applied in digital substations,introduction of implementation schemes used in digitized transformation of Jiangsu power grid is presented in this paper.Detailed illustration focused on four issues including sample signal transmission,merging unit configuration,synchronization of sampled values,switching and juxtaposition problem of digital voltage signals is also presented.At last,solutions that can be applied in substation transformation are proposed.
