在电力系统中把交流电压、电流要素等经过变换、滤波、S/H及A/D转换后得到对相应的离散化数据序列,并存储过程称为交流电量采集。电量的实时精确的采集与电网运行的稳定,以及用户用电的可靠性息息相关。因此需要实时的采集各种电参量,用来监控以保证电网的稳定。同步采样,是指在不同采样点同时开始采样,其目的
In the power system to AC voltage, current elements such as transformed, filtered, S / H and A / D converted to the corresponding discretization of the data sequence, and the storage process is called AC power acquisition. Accurate real-time acquisition of power and the stability of grid operation, as well as the reliability of electricity users are closely related. Therefore need real-time acquisition of various electrical parameters, used to monitor to ensure the stability of the power grid. Simultaneous sampling refers to the simultaneous sampling starting at different sampling points for the purpose
