Design and data preprocessing of data acquisition system based on photovoltaicenergy storage hybrid system

To establish the accurate mathematical model in identification, real input-output data might be acquired. Therefore,it based on ADu C812 data acquisition chip as the core of slave acquisition MCU,with Lab- VIEW software as development environment of PC. It has settled up a data acquisition module for storage- connected photovoltaic system of optical storage and realized acquisition, storage and remote monitoring of voltage, electric current,photovoltaic cell plate temperature and solar radiation intensity. Through the test, test data along with the relative error of test data show that the relative error is small, and it's within the limit of estimation.It has further verified the designing rationality of the data acquisition module and the accuracy of the data.
