Data Matching and Validation Method for Hererogenous Information System Based on Power System Structure Characteristics

This paper proposes a data matching and validation method based on structure characteristics of power system. On the basis of traditional string matching,the topology structure is considered. Further more,the accuracy of match result is well verified via grid structure. This method is applied to a provincial online verification system for relay protection setting. The match result of a time section verified the validity and the correctness of the algorithm.
