摘　　要：根据现代电力系统及其自动化的发展趋势,以及电力调度生产7×24h不间断运行的特点,指出新一代能量管理系统(EMS)设计中必须考虑SCADA数据来源的多样性。文章详细总结了EMS中多数据源技术的应用情况,分析了多数据源技术对电网调度中心原始数据采集的重要性,在此基础上研究了多数据源应用的在线切换优选规则,有效地保证了基础电网运行实时数据和历史数据的正确、完整、可靠,同时保证了自动发电控制(AGC)、区域电网控制性能标准(CPS)等重要电网控制程序更高的可用性和可靠、正确的运行。Base dupon the development tendency of the modern power system and it sautom ation and also the inherent features caused by the 7×24h incessant operation of the power dispatch work,it was pointedout that the multiplicity of the SCADA data source must be taken into consideration in the new generation design of Energy Management System (EMS).The conditions of the application of the multiple data sourcete chnique to the EM Shave been summarized and the importance of the multipled ata sour cetechnique tothecollectionofthe firs than dinfor mation of the grid dispat ching center has been analyzed also.Basedupon the above-mentioned resear chresults,there gulation sused to guide the preferential selection of the on-lines witching applied to the multiple data sour cetechnique has been studied,
