Notice of Retraction A SOA based framework for multi-level users oriented training courses for digitalized substation

Operators for digitalized substation differ in age, education and working experience, so it is hard to provide a universal set of courses for all. A framework based on Service Oriented Architecture (SOA) is proposed. Aiming at different level users, multiple similar services form a Differential Services Cluster (DSC), providing different courses by merging contents of courses through a Level Oriented Algorithm (LOA). DSC acts as the storage for course ingredient. LOA constructs a course for user according to his role and other background settings. The innovation is that antagonism mode borrowing from game is introduced. The response from most users indicates that the new mode is very attractive. While for old and less educated users, the system is less acceptable due to current short of materials.
