摘　　要：针对电力多级数据体量的增大,冗余数据量随之增大,造成电力大数据应用质量降低的问题,设计基于小波分析的电力多级冗余数据校验系统。预处理电力多级数据后,引入小波分析算法分解处理电力多级数据,提取最大权重系数对应分解部分数据的代表特征。基于流水线策略检测电力多级冗余数据,并通过并行化技术对其进行消除处理,从而实现电力多级冗余数据的校验。实验数据显示,应用设计系统后,冗余数据查全率最大值达到了97.56%,冗余数据校验误差最小值为2%,证实了设计系统具有较好的冗余数据校验效果。Aiming at the problem that the amount of redundant data increases with the increase of the volume of power multi-level data,resulting in the reduction of the application quality of power big data,a power multi-level redundant data verification system based on wavelet analysis is designed.After preprocessing the power multi-level data,the wavelet analysis algorithm is introduced to decompose the power multi-level data,and the representative features of the decomposed data corresponding to the maximum weight coefficient are extracted.The power multi-level redundant data is detected based on the pipeline strategy and eliminated by the parallelization technology,so as to achieve the verification of the power multi-level redundant data.The experimental data shows that after the application of the design system,the maximum recall rate of redundant data reaches 97.56%,and the minimum error of redundant data verification is 2%,which proves that the design system has good redundancy data verification effect.
