摘　　要：基于Prony方法提出了准同步采样算法,精确估算出采样信号的基波频率,并通过牛顿插值法对电能信号进行插值重构,开发出了具有低运算量、低信号传输成本的测量系统,优化了配电测量系统的资源配置.Based on Prony algorithm,we proposes the quasi-synchronization sampling algorithm.The fundamental frequency of the sampling signals is precisely estimated and the power signals are reconstructed by Newton interpolation algorithm.We finally develop a measurement system with low computational cost and low signal transmission cost and optimize the resource allocation of the power distribution measurement system.
