As for the distributed control system(DCS)developed in different times,how to share and integrate the data of DCSs plays an important role in building the comprehensive supervisory information system(SIS)in a substation.This paper proposed heterogeneous data sharing and integration technology based on extensible markup language(XML)and constructed a kind of heterogeneous data sources integration Middleware(HDSIM),which uses XML as the data exchange format and makes XML schema establish a public model with Mediator integration pattern,to achieve the integration of data collection,monitoring,analysis and protection in the substation.Finally,the results of the application confirm the validity of this data integration technology.
