| Abstract: | 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. |
