LASER-TESTING RIG : Measurement System for evaluation of Shape of concentrating reflector for solar collector Absolicon X10

This Thesis project is a part of the all-round automation of production of concentrating solar PV/T systems Absolicon X10. ABSOLICON Solar Concentrator AB has been invented and started production of the prospective solar concentrated system Absolicon X10. The aims of this Thesis project are designing, assembling, calibrating and putting in operation the automatic measurement system intended to evaluate the shape of concentrating parabolic reflectors.On the basis of the requirements of the company administration and needs of real production process the operation conditions for the Laser testing rig were formulated. The basic concept to use laser radiation was defined.At the first step, the complex design of the whole system was made and division on the parts was defined. After the preliminary conducted simulations the function and operation conditions of the all parts were formulated.At the next steps, the detailed design of all the parts was conducted. Most components were ordered from respective companies. Some of the mechanical components were made in the workshop of the company. All parts of the Laser-testing rig were assembled and tested. Software part, which controls the Laser-testing rig work, was created on the LabVIEW basis. To tune and test software part the special simulator was designed and assembled.When all parts were assembled in the complete system, the Laser-testing rig was tested, calibrated and tuned.In the workshop of Absolicon AB, the trial measurements were conducted and Laser-testing rig was installed in the production line at the plant in Soleftea.

Universal Experimental Measurement System «Sun-Walker» : Automotive measurement system for the evaluation of the solar irradiation distribution for the tests of the solar concentrated systems.

This Thesis project is a part of the research conducted in Solar industry. ABSOLICON Solar Concentrator AB has invented and started production of the prospective solar concentrated system Absolicon X10. The aims of this Thesis project are designing, assembling, calibrating and putting in operation the automatic measurement system intended to evaluate distribution of density of solar radiation in the focal line of the concentrated parabolic reflectors and to measure radiation from the artificial source of light being a calibration-testing tool.On the basis of the requirements of the company’s administration and needs of designing the concentrated reflectors the operation conditions for the Sun-Walker were formulated. As the first step, the complex design of the whole system was made and division on the parts was specified. After the preliminary conducted simulation of the functions and operation conditions of the all parts were formulated.As the next steps, the detailed design of all the parts was made. Most components were ordered from respective companies. Some of the mechanical components were made in the workshop of the company. All parts of the Sun-Walker were assembled and tested. The software part, which controls the Sun-Walker work and conducts measurements of solar irradiation, was created on the LabVIEW basis. To tune and test the software part, the special simulator was designed and assembled.When all parts were assembled in the complete system, the Sun-Walker was tested, calibrated and tuned.

Solar Energy assessment based on weather station data for direct site monitoring in Indonesia

This thesis evaluates different sites for a weather measurement system and a suitable PV- simulation for University of Surabaya (UBAYA) in Indonesia/Java. The weather station is able to monitor all common weather phenomena including solar insolation. It is planned to use the data for scientific and educational purposes in the renewable energy studies. During evaluation and installation it falls into place that official specifications from global meteorological organizations could not be meet for some sensors caused by the conditions of UBAYA campus. After arranging the hardware the weather at the site was monitored for period of time. A comparison with different official sources from ground based and satellite bases measurements showed differences in wind and solar radiation. In some cases the monthly average solar insolation was deviating 42 % for satellite-based measurements. For the ground based it was less than 10 %. The average wind speed has a difference of 33 % compared to a source, which evaluated the wind power in Surabaya. The wind direction shows instabilities towards east compared with data from local weather station at the airport. PSET has the chance to get some investments to investigate photovoltaic on there own roof. With several simulations a suitable roof direction and the yearly and monthly outputs are shown. With a 7.7 kWpeak PV installation with the latest crystalline technology on the market 8.82 MWh/year could be achieved with weather data from 2012. Thin film technology could increase the value up to 9.13 MWh/year. However, the roofs have enough area to install PV. Finally the low price of electricity in Indonesia makes it not worth to feed in the energy into the public grid.

Uppföljning och utvärdering av det balanserade styrkortet : Är balanserat styrkort ett värdeskapande och strategiskt instrument inom den kommunala verksamheten?

The need to steer economic development has always been great and as management model has the balanced scorecard has been popular since the mid- 1990s, mainly in the private sector but also in the municipal sector. The introduction of the balanced scorecard has been primarily to organizations to see more than economic dimensions. The Balanced Scorecard was originally a measurement system, and today it works more as a strategic instrument. In our study is a case study to evaluate a municipality and how they make use of the balanced scorecard as a tool for strategic and value-adding work in municipal activities. In the local business is it important that the organization adapts the balanced scorecard, so it fits on the basis that it is a politically driven organization, with mandates, committees and administrations. In our study, we used a qualitative method with a deductive approach. In the study, we have gathered information through a case study where we interviewed 7 people in leading positions. In our analysis and results section, we came to the conclusion that the municipality does not use the balanced scorecard correctly. We also found that the balanced scorecard as a tool for value creation and strategic planning does not work in a favorable way. In our study, we see difficulties with the implementation of the balanced scorecard. If the municipality has invested in implementing the balanced scorecard at all levels of the business so the municipality would be able to use it on one of the activities more adequately. When the municipality is a politically driven organization, it is important that vision alive and changing based on the conditions that reflect the outside world and the municipality in general. Looking at a vivid vision, goals and business ideas, it's balanced scorecard in line with how a balanced scorecard should look like. The municipality has a strategic plan in terms of staff and employees at large. In the study, we have seen that the strategic plan is not followed up in a good way and for the business favorably, the municipality chooses the easy way out for evaluation. Employee participation to changes and ongoing human resources management feels nonexistent. However, as has been the vision of creating empowered and motivated employees. In our conclusion, we describe how we in our study look at the use of the balanced scorecard in municipal operations. We can also discern that a balanced scorecard as a tool for value creation and strategic work is good if it is used properly. In the study, we have concluded that the municipality we have chosen to study should not use the balanced scorecard when you have not created the tools and platforms required for employees, civil servants and politicians to evaluate, monitor and create a living scorecard change over time. The study reveals major shortcomings in the implementation, evaluation and follow-up possibilities, and the consequence of this is that the balanced scorecard is not - 4 - preferable in municipal operations as a strategic instrument for value creation and long-term planning.
