Gasturbinen-Kraftwerke
(2022)
Das Wort Gasturbine rührt nicht vom Brennstoff her, der gasförmig, flüssig oder sogar fest sein kann, sondern vom gasförmigen Arbeitsmedium, das bei üblichen offenen Gasturbinen Luft und nach der inneren Verbrennung Luft-Rauchgas ist. Der Brennstoff wird dem angesaugten Arbeitsmedium Luft zugeführt, so dass eine innere Verbrennung stattfindet. Das Abgas wird bei den üblichen offenen Gasturbinen in die Atmosphäre abgegeben.
The design of control systems in large-scale CPV power plants will be more challenging in the future. Reasons are the increasing size of power plants, the requirements of grid operators, new functions, and new technological trends in industrial automation or communication technology. Concepts and products from fixed-mounted PV can only partly be adopted since control systems for sun-tracking installations are considerable more complex due to the higher quantity of controllable entities. The objective of this paper is to deliver design considerations for next generation control systems. Therefore, the work identifies new applications of future control systems categorized into operation, monitoring and maintenance domains. The key-requirements of the technical system and the application layer are identified. In the resulting section, new strategies such as a more decentralized architecture are proposed and design criteria are derived. The contribution of this paper should allow manufacturers and research institutes to consider the design criteria in current development and to place further research on new functions and control strategies precisely.
The communication system of a large-scale concentrator photovoltaic power plant is very challenging. Manufacturers are building power plants having thousands of sun tracking systems equipped with communication and distributed over a wide area. Research is necessary to build a scalable communication system enabling modern control strategies. This poster abstract describes the ongoing work on the development of a simulation model of such power plants in OMNeT++. The model uses the INET Framework to build a communication network based on Ethernet. First results and problems of timing and data transmission experiments are outlined. The model enables research on new communication and control approaches to improve functionality and efficiency of power plants based on concentrator photovoltaic technology.
