The invention relates to a method for automatically generating an E-format file of a stability control strategy. The method comprises the steps of acquiring data attributes and running status; defining an on-duty offline strategy; calculating a correlation coefficient set of the data attributes and the offline strategy, and a proportional weighted coefficient set of configurable data attributes and the offline strategy; calculating a final correlation coefficient between the data attributes and the offline strategy to determine whether the data attribute is related to a specific offline strategy; combining the related data attributes to form an offline strategy member item, and forming a single offline strategy by a plurality of member items under the same offline strategy; judging whetherthe offline strategy is in an on-duty offline status; and writing all the on-duty offline strategies into an E-format offline strategy file and automatically sending the file to a master station. Themethod in the invention frees from the problems of poor timeliness of manual maintenance of offline strategy files and high requirements on the quality of maintenance personnel, improves the real-time performance of the on-duty offline strategy update, and reduces the maintenance time and labor cost.
