Power system stabilizers (PSSs) are used to enhance damping of electromechanical oscillations occurring in power systems after small or large disturbances. PSSs designed by classical control methods have been widely used to accomplish this task. In this study, a new method based on big bang-big crunch algorithm is proposed to optimize the parameters of PSSs with a conventional structure in order to stabilize the system and to increase damping of this type of oscillations. The success of the proposed method is demonstrated on a two-area test system through simulations in which both local and inter-area oscillations are effectively damped.

Because soft set and information system are both dealing with objects and attributes or parameters, they must have the intimate connections. However, this connection is still not completely understood. we will study the relations between soft set and information system. In this paper, The category SS(U) of soft sets over U is discussed, then we prove that the category SS(U) is a topos.

The effort for design and implementation of process automation systems increases with the complexity of modern production plants. To shorten the implementation phase we propose a conceptual approach for automated code generation for programmable logic controllers (PLCs) based on knowledge acquisition from standardized engineering artifacts and their corresponding tool database. Ontologies are defined for each engineering domain artifact, representing the concepts and relations specified in the associated domain standards. An automated data extraction and population of the domain-specific ontologies together with semi-automated mapping definitions between common engineering objects then enables a rulebased code generator to query the ontologies. The query results are translated afterward into PLC code by applying a rule transformation algorithm.
