摘要(Abstract):
常规变电站采用电流/电压互感器,而智能变电站是采用电子式互感器和合并单元,实现交流采样的数字信号采集。根据目前投运的智能变电站交流采样模式,从工程实际出发,对各种交流采样异常状态进行分析,并提出相应的处理方法。
This paper describes the mode of digital AC sampling in intelligent substations used nowadays.Through the analysis on various abnormal situations of AC sampling based on the engineering practice,this paper puts forward corresponding processing methods.
