Abstract:The paper describes the significance and necessity of measurement of grounding resistor of electric power system. It points out the shortcomings of traditional method. In order to overcome the disadvantage of it, we try to use a new method to measure grounding resistor intelligently , which add current power to measure and frequency analyse to get the result. We set up an automatic ,real-time ;online practical system based-on MCS-51 single chip control and disposal, it can get the radical waveform by FFT, which change signals from real field to frequency field .The system improve the precision and agility of grounding resistor testing. It makes a way come true that does not affect normal working of power system and improve measurement precision .It will bring great application value in electric power system. 目录 电网系统对接地电阻的智能测量相关范文 |
