摘要
在交流电路中交流电量的测量,特别是有功功率的测量采用微机直流采样的方式误差大,精度低。本文研究的是交流电量微机同步采集技术,实践证明:这种微机同步采集电路可使电力系统中的微机监控系统取得结构简化,硬件投资省,测量精度高的效益。
In A,C cirucit the electric quantity,especially,the real power is measured byusing the way of collecting D. C of the micrcomputer,which is raising error and reducing ac-curacy of measurement also raising investment of hardwere.In this paper,the micrcomputersynchronous collecting technique of A,C electric quantity is studied.It is verified throughpractice that the technique can simplify the stracture of micrcomputer control system,saveinvestment of hardwere,raise accuracy of measurement and reduce error.
