Laboratories

The fuel-lab is a research laboratory that provides analyses for liquid fuels. In addition to research projects, it offers services from single analysis to larger customer projects. Ask for more information: fuellab@uwasa.fi

The ICE-lab comprises a medium-speed Wärtsilä 4L20 engine for marine and power plant applications, loaded by an ABB alternator. The test bench uses a Speedgoat model-based control system. An ABB drive enables engine operation at variable speeds. The exhaust system makes it possible to study various exhaust cleaning systems. The large measurement system covers determination of engine performance, combustion analyses, gaseous and particulate emissions, air and exhaust pressures, temperatures and flow rates. The University of Vaasa has also validated in-house and commercial toolchains for simulation of engine and propulsion systems.

Within the geoenergy laboratory, there is mobile research equipment suitable for various field measurements. The DTS measurement device (distributed temperature sensing with fibre optics) has been used to study heat transfer, for example, in sediment and asphalt fields. The TRT carriage has been constructed for testing the thermal response of boreholes and other shallow geothermal sources. These mobile research devices enable on-demand research anywhere in Finland.

The Future Reliable Electricity & Energy System Integration laboratory (FREESI-lab) consists of Protection, Automation and Communication (PAC) laboratory for testing and training the IEC 61850 based protection systems as well as OPAL-RT OP5600 real-time simulator platform, which at present time, enables controller hardware in the loop (CHIL) simulations of Smart Grids. The FREESI-lab is connected to the Sundom Smart Grid living lab environment, which is a real medium voltage grid providing a continuous IEC 61850 based data stream from twenty nodes. The ongoing and future investments into the FREESI-lab will enable the expansion of research activities and cooperation especially in the area of smart and flexible energy systems.
