Against the background of lack of a unified data coding standard in the electric power dispatch center， real-time data matching is the crucial step before implementing interfaces between the energy management system（EMS） and the verification system as well as the key premise of developing the verification system from off-line to on-line. In view of the characteristics of EMS real-time data， a new method for data matching between EMS and the verification system is put forward that adopts the Levenshtein distance to judge the level of similarity， and improves the traditional matching method in five aspects， that is， weights moving， spelling index， exchange operation， adjacent spaces， and level association. Furthermore， the new method improves the matching rate and accuracy and minimizes manual involvement to a degree. The results of the example show the effectiveness and correctness of the new method.
