Control System for Cogenerative Power Plants

The paper presents a distributed control system for the realization of cogenerative supply of electricity and heat and, in given case, for their combination with waste heat recovery, particularly in combined (gas-steam) cycle industrial power plants. Modern electric power plants are large complex systems with many processes whose operations need to be optimized. The electrical networks are designed for transmission, repartition and distribution of electrical energy, so that they present various structures. An optimization problem is usually a mathematical model, where we wish to minimize a numerical value that represents something like costs, energy losses, risks, errors etc or maximize something like profit, quality, efficiency. Today all the systems that manage the security are characterized by the complexity of their major functions like identification, authentication, access control and data protection. The implementation of these functions is usually and objectively based on a trusted model that uses a trusted architecture, which is the platform of the security architectures.
