These standard representations allow you to investigate different concepts at the very early stages of the design, even before any CAD (computer-aided design) geometry is available. Parameters can be refined and details can be added as they become available, making 1D CAE a perfect complement to detailed 3D CAE throughout the entire design cycle.

The components are analytically defined, and have input and output ports. Causality is created by connecting the inputs of a component to the output of another one (and vice-versa). The resulting mathematical system has a very limited number of degrees of freedom compared to 3D CAE. This solution speed, the openness of 1D CAE software to different types of software codes and the real-time capabilities allow you to streamline the system development process. 1D CAE offers you an open development approach, starting from functional requirements to physical modeling and simulation, enabling concurrent engineering of mechatronic systems in a collaborative design environment.

  • Dynamic Simulation of a Combined Cycle for Power Plant Flexibility Enhancement
    E3S Web of Conferences 113, 01005 (2019) https://doi.org/10.1051/e3sconf/201911301005 SUPEHR19 Volume 1 Dynamic simulation of a combined cycle for power plant flexibility enhancement Adrien Reveillere1, * , Martin Longeon1 and Iacopo Rossi2 1Siemens PLM 69006, Lyon (France) 2University of Genoa, 16145, Genoa (Italy) Abstract. System simulation is used in many fields to help design, control or troubleshoot various industrial systems. Within the PUMP-HEAT H2020 project, it is applied to a combined cycles power plant, with innovative layouts that include heat pumps and thermal storage to un-tap combined cycle potential flexibility through low-CAPEX balance of plant innovations. Simcenter Amesim software is used to create dynamic models of all subsystems and their interactions and validate them from real life data for various purpose. Simple models of the Gas Turbine (GT), the Steam loop, the Heat Recovery Steam Generator (HRSG), the Heat Pump and the Thermal Energy storage with Phase Change material are created for Pre- Design and concept validation and then scaled to more precise design. Control software and hardware is validated by interfacing them with detailed models of the virtual plant by Model in the Loop (MiL), Software in the Loop (SiL) and Hardware in the Loop (HiL) technologies. Unforeseen steady state and transient behaviours of the powerplant can be virtually captured, analysed, understood and solved. The purpose of this paper is to introduce the associated methodologies applied in the PUMP-HEAT H2020 project and their respective results. 1 Introduction A Combined Cycle Power Plant (CC) [1] converts energy contained within the fuel into electrical energy, through two different cycles in one simple plant, to improve efficiency.
