Storage and analysis methods for parameters of power system element model

The invention provides a storage method for a power system element model. The storage method comprises the steps of: defining a template of the power system element model, wherein template information comprises an element type corresponding to the model, a model type, a model transfer function block diagram, a model application range and a model descriptive annotation; defining parameter information in the template; establishing hierarchical relationships between the model template and parameter definitions contained in the model template; and storing parameters of the power system element model in a unified format. In addition, the invention furthermore provides an analysis method for the parameters of the power system element model. The analysis method comprises the steps of: associating a set of specific parameters of a model with the model template and the parameter definitions according to the claim 1 by utilizing the information of the element type and the model type; and obtaining stored parameter values and parameter definitions in sequence to finish the analysis operation. The model template self-definition based element parameter storage method has very high universality and expandability and very wide application fields.
