Taking advantage of the improvements made in computer tools. Electricite de France is undertaking the overall renovation of its power control centers in order to optimize the operation of the generation-transmission system from the savings and security point of view. The alarm processing function has been set into a consistent whole with different synthesis levels in order to show the operator only the significant events. This process has needed an ergonomic analysis of operator activity. From the results of this analysis the authors defined the processing operations to assist the operator in understanding the situation and when possible to aid functions for decision making. >
