6kV电网微机自动监测系统

Microcomputer-based Automatic Monitoring System of 6kV Live Wire Entangglement

介绍了一种基于交流采样的６ｋＶ电网微机自动监测系统。采用傅里叶级数展开计算法、实现对电压、电流、功率因数和电量的测量和计算；利用软件完成了需要较多硬件才能实现的多种功能．节省了大量的硬件投资，减少了日常维护量。该系统的应用对于提高供电系统运行效益，保证安全供电具有重要意义。

This paper describes a microcomputer automatic monitoring system of 6kV live wire entangglement which is based on AC sampling.It uses Fourier series in expanding calculus, to achieve the measuring and calculation of volt,current, power factor and quantity of electricity.Software is taken to achieve multiple functions instead of much more hardware, and has saved much investment in hardware,and minimised daily maintenance.The application of the system is of great significance in improving benefits of power distribution system operation and ensuring the safety of power supply.
