To solve the issues of high network requirement

low retrieval efficiency and the poor reliability of the traditional power quality monitoring data management model

a data management scheme for power quality monitoring data based on mobile agents is proposed and implemented. The programs which manage data are packaged as mobile agents

and are dispatched from the main station to the substations in which the original monitoring data are stored. Then the mobile agents complete the data processing on the spot and only the results are returned to the main station. The scheme is implemented via an Aglets platform and the test results indicate it can significantly reduce the retrieval time

improve network adaptability and reliability of the system. Needing no substantial reconstruction of the existing system

this scheme has great engineering application value.
