| Abstract: | The reason of errors in normal algorithm by software in AC sampling unit is analyzed. A novel optimization method of synchronous sampling in software is put forward in this paper, in which the sampling period is adjusted dynamically in a signal period. The speedy algorithm is detailed that the program run speedily by the rule about residue and round. Included are analysis of the errors of synchronous sampling and the simulation. The method is completed by programming in Matlab. After application to the electric power automation feeder remote terminal unit (RTU), the application of the method can improve the sample accuracy and the real time capability. |
