A model identification apparatus which can provide accurate model parameters for power system simulation is designed, and the design focuses on its data acquisition unit. The unit adopts highly-integrated modularization design, and uses MCU C8051F410 as the core. The analog-to-digital conversion module is made up of 4 pieces of AD7606 to realize synchronous sampling of 32 input signals. The data storage module consists of document management control chip CH376S and U disk to solve the mass-data storage problem. All these modules coordinate communications by subroutine calls. Measurement on different voltage signals of multiple channels proves that data acquisition unit realizes the predefined function, and the accuracy meets the requirement.
