Pre-study and system design of a mobile platform simulator system

Sammanfattning: There are many ways to produce energy, using e.g. gas or hydro turbines. To guarantee a stable power output, it is important to consider components that could control and adjust the output power automatically. The intention of this thesis work is to carry out a pre-study and system design of a mobileplatform simulator system that could be used by companies like Siemens and help them to reduce their OPEX (Operational expenditure) and easily evaluate their AVR (AutomaticVoltage Regulator) solutions and test improvements. In this document, Siemens has decided to call the simulator system, MPSS (Mobile Platform Simulator System). The pre-study includes the theory behind energy production, synchronous generator, simulator system, AVR, control systems and electrical grid. Furthermore, the pre-study includes selection of the proposed components for the simulator system and design of the complete simulator system that will be built by the Siemens R&D engineers at a later stage. The Mobile Platform Simulator System (MPSS) is intended to test the AVR performance, which is a component with its prime purpose being to maintain the output voltage values from the generator at a fixed value, regardless of the current being drawn by the load. It is important that these output values are constantly regulated during the process of producing electricity, so that problems such as overvoltage, overcurrent etc. can be prevented. The MPSS will also be able to simulate real working scenarios e.g. from the different components of an energy production system, such as gas and hydro turbine, synchronous generator, AVR, electrical grid and serve for personnel training. The MPSS will consist of three main components; Simulator, AVR and control system. Therefore, the report will initially provide the background and general theory behind the synchronous generator, AVR and control system used in power generation systems. General information about the electrical grid is also provided. Furthermore, the report suggests the best possible choice for the necessary components to build a MPSS as well instructions on how to perform event simulation. The necessary documentation, including a circuit diagram to support the building of the MPSS by the R&D engineers at late stage, is also provided. Finally, the general analysis of the technical and non-technical aspects related to the choice of components, work process, method and result are discussed in the end of this report.
