摘要
交流电量测量是水电站自动化中的基本环节。文章作者在湖南省嘉禾县调塘水电站实现微机监控系统中研制了基于8098单片机的交流采样,通过初步调试证明:用微机来直接采集交流电量可使系统结构得以简化,采集数据稳定性及精度均较高,便于现场调试,可以充分利用8098芯片的功能,满足中小型电站测量要求,具有实用价值。
The Measuring AC electy energy is a key link in the automatization of hydropower sta- tions. Based on the AC sampling of 8098 single chip microcomputer,the authors developed a microcom- puter monitoring system for Diaotang Hydropower Station in Jahe County of Hunan Province. The preliminary debuggings have proved that: the structure of the monitoring system was simplified with di- rectly sampling AC electy energy by microcomputer; the stability and accuracy of the sample data are higher; the system is conenient for field debugging; the system can fully utilize the function of 8098 chip and satisfy the measuring demand for mid-small hydropower stations; the system is of practical value.
