Abstract:

The design of the power supervisory control and data acquisition system is introduced and the scheme of system design is proposed in the paper.The signal recuperation circuit,A/D converter circuit,FPGA circuit,USB interface circuit and power module circuit are described in detail.The USB+FPGA structure is adopted in power supervisory control and data acquisition system,so the transmission rate is improved and the data storage and preprocessing flexibility are increased,which has strong applicability.

Key words: power supervisory control;data acquisition;A/ D converter;USB interface
