Under the restriction of insufficient openness of the architecture of existing commercial power system calculation and analysis software, based on the features of power system computation analysis the hierarchical division of power system computation analysis is performed and two key technical problems in the design of composite automatic calculation and analysis tool are proposed. Based on autonomous decentralized system model and open service gateway initiative (OSGi) specification, a standardized overall design of a composite automatic calculation and analysis tool is completed to provide a generalized method for the implementation of composite automatic calculation and analysis functions. The completed design involves following aspects: a data-change-driven case generation process; the integration and call of standard calculation and analysis tool in PSD power system calculation and analysis software; the design of task scheduler to implement the management of computing kernel and the scheduling of computational task. Finally, taking screening of fault samples causing UHV power grid splitting and automatic validity checking of security and stability control measures as examples, the feasibility and the practical effect of the overall design and realization of the proposed composite automatic calculation and analysis tool are illustrated.
