摘要
为了辨识建立光储联合供电系统的精确数学模型,需要采集系统的真实输入/输出数据。故采用以ADu C812数据采集芯片为下位机核心,以Lab VIEW为上位机开发环境的方法,搭建了光储联合供电系统的数据采集模块,实现光储联合供电系统中电压、电流、光伏电池极板温度和太阳辐射强度的采集、存储与远程监控。实验表明,测试数据与显示数据的相对误差较小,并且在估算的误差限之内,从而验证了数据采集模块设计的合理性和采集数据的准确性。
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.
