摘　　要：DSP技术在电力测量中的应用是测量仪器数字化的一个发展方向.为了解决在配网线路测量与保护技术中采样A/D不稳定性,采用TMS320LF2407DSP内嵌的ADC电路实现35kV/110kV线路测量和保护的方法,给出了详细的电路设计和有关程序设计.经A/D采样后的电流、电压送入DSP芯片,进行相关处理,得到所需要的电流和电压的平均值、有功功率及功率因数等电力参数.系统可以通过通信模块进行远程测量和数据传输,具有良好的灵活性、可升级性和高效性等特点.The DSP technology is what can make measurement apparatus become digital.How to use DSP in electric power measurement system is introduced.To reduce the error in A/D sample of circuit measurement and protecting, the method about the 35kV/110kV circuit measurement and protecting is given to show program and designs of circuit by using the inbeded ADC of TMS320LF2407.Current and voltage is transmitted to DSP chip after A/D, and handled with DSP. In this way, the average value of current and voltage, power, as well as power factors can be gained and stored. This system has another function that remote measurement and data transmission can be made by communication module.The scheme has many properties such as flexibility, expandability and high efficiency.
