Architecture design of power system fault calculation based on cloud computing technology

This paper presents an architecture of power system fault calculation based on cloud computing technology to solve the problems of the current fault calculation system, which is caused by the insufficient calculation ability. The existing fault calculation system can not meet the requirements of the calculating efficiency and accuracy with the expansion of power system. The concept, characteristics, advantages, structure of cloud computing and service oriented architecture (SOA), as well as the architecture of the proposed system are described in detail in this paper. Besides, the cloud computing technology and SOA are applied to the fault calculation system, reaching the elastic scaling of the calculation and storage, reliable disaster recovery of the system, and a higher interoperability. To validate the design, the proposed system is applied to an actual power system, and the operation effect has proved its feasibility and superiority.
