摘　　要：为解决电力系统灾备中心资源利用率低,灾备业务流程复杂等一系列问题,提出将云计算技术引入的具体思路。探讨了云计算在电力系统应用的可行性和必要性,设计并实现了云计算资源管理平台,对平台的体系架构和关键技术进行了研究,对平台带来的经济和管理效益进行了讨论。云计算资源管理平台通过服务器及存储虚拟化、资源整合建模、资源调度引擎等技术,实现了异构资源整合,资源按需分配、在线动态调配、应用动态迁移以及流程管理,并结合虚拟机镜像技术,将验证环境进行备份以便后期的快速部署与数据验证。目前,云计算资源管理平台已经在电力系统灾备中心进行实际应用,解决了灾备中心面临的问题,并使灾备业务由原来的手工操作模式转变为具备IT支撑的流程化自动化模式。In allusion to low resource utilization of power system data recovery center and complex flow of data recovery business,a concrete thinking of leading cloud computing into data recovery is proposed.The feasibility and necessity of applying cloud computing in power system application is discussed,and a cloud computing resource management platform（CCRMP） is designed and implemented.The architecture of CCRMP and corresponding key technologies are researched,and the economic and management benefits brought by CCRMP are analyzed.By means of virtualization of server and storage,resource consolidation and modeling,resources allocation engine and so on,the heterogeneous resource consolidation on CCRMP,resource allocation on demand,dynamic online resource allocation,dynamic migration of application and workflow management is implemented.Combining with mirror technology of virtual machine CCRMP can back up the verification environment for the rapid deployment and data validation in the future.At present,CCRMP is practically applied in power system data recovery center and the problems to be faced with in the center are solved,and CCRMP makes data recovery business turning from original manual operation mode into standardized and automatic mode with IT support.
