Kehe Wu · Power System Protection and Control · 2012
In order to meet the requirements of short-term decision analysis in evaluation support system of power grid investment benefit,the ODS(Operational Data Store) technology is applied to provide subject-oriented,integrated,variable,real-time and fine-grained data by analyzing the characteristics of its data integration.According to the current situation of the ODS-layer of power enterprise data center,a system architecture of data center in-depth application is proposed.Then,combined with IEC 61970/61968 standard specifications,the data model of ODS is established.Besides,the solutions to key problems of data storage and update strategies and data quality control are discussed.Good practical application demonstrates the value of this method.
