In process industries, compressor plants provide process fluids with certain flows and pressures. The plant behavior may change over the entire life cycle due to component-specific time-variable factors. Control valves applied in compressor plants are affected by time-variable factors. Their modeling with consideration of specific time-variable factors is described in this paper. Control valves ensure...
A prerequisite to achieve energy efficiency in production through optimization is the possibility to use simulation models to predict the consequences settings, decisions and actions have on the energy consumption and thus on the lifecycle cost of production machines. But today’s production systems are dominated by agile structures and rapid changes of general conditions so that predictive energy...
Guaranteeing energy efficient operation of production systems through a-priori optimization is an extremely complex task. We therefore propose an alternative approach where controls can decide locally if an energy reduction is possible and set components to energy-optimal states. In this paper we present results from the research group ECOMATION describing the information flow that generates energy...
