Abstract [en]

Due to advancements in porous ceramic materials, the concept of utilizing gas turbines to produceelectricity from solar power is close to bringing a commercial competitive product to market. Since theconcept developed in the Department of Energy Technology at KTH in collaboration with otherEuropean institutions aims for a solution that utilizes small-scale technology, the power rating is lower,compared to traditional gas turbines.

One challenge that this creates is that the specific cost per power unit of the different systemcomponents is going to increase. With the objective of limiting this cost increase, for the specificcomponent of turbine's control, this work describes the selection and implementation of an open sourcehardware controller.

Based on previous development at the department, the work includes the dynamic simulation of a SolarMicro Gas Turbine, including starting and stopping sequences, control strategy assessment, and theimplementation of this strategy on the selected hardware, an Arduino based PLC controller. The controlprogram is tested in an emulated environment consisting of simple electronic circuits. The selectedhardware proves suitable for the tested tasks. Future work consists on conditioning some sensor outputsto the acquisition capabilities of hardware, and implementation in the real system including writing of thefinal control program.

Abstract [sv]

Tack vare framsteg inom porösa keramiska material, så är principen att använda gasturbiner för attproducera el från solenergi nära att få ett kommersiellt genombrott. I konceptet som utvecklas påInstitutionen för Energiteknik vid KTH i samarbete med andra institutionerna inom EU strävar man efteren lösning som utnyttjar småskalig teknik. Därför är märkeffekten lägre, jämfört med traditionellagasturbiner.

En utmaning som detta skapar är att den specifika kostnaden för de olika systemkomponenterna kommeratt öka. I syfte att begränsa denna kostnadsökning avseende turbinregleringen, beskrivs i detta arbete val avoch implementering i en öppen hårdvara.

Baserat på tidigare utveckling vid institutionen omfattar arbetet en dynamisk simulering av en soldrivenmikrogasturbin, inklusive start och stopp sekvenser samt reglerstrategi. Implementering av strategin i denvalda hårdvaran, ett Arduino-baserat PLC-system. Styrprogrammet testas i en emulerad omgivning sombestår av enkla elektroniska kretsar. Den valda hårdvaran visar sig vara lämplig för de testade funktionerna.Framtida arbete består i att anpassa olika sensorers utsignaler till datainsamlingsfunktionerna i hårdvaranoch integrera dem i det verkliga systemet samt utveckling av ett komplett styrprogram.
