| dc.description.abstract | Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses. If the power plant can be operated in island operation it would lead to a reduction of these interruptions. The assignment has been to organize the different machines in the paper mill during island operation so that the generator can work in a desirable and optimal way. These machines are mainly pumps and compressors that are used for the support of freshwater and during potential fires. Lighting in the facilities has also been a priority during island operation. To enter island operation manually the breaker between the system and the island will be opened by the operator. An automatic connection occurs when there is a failure in the external grid, the breaker will then open automatically. In the case of a manually connected island, the desired power production in the island will be 2.76 MW. If an automatic connection occurs, the desired power will be 1.87 MW. The obtained results were very satisfactory in comparison with the expectations. The island frequency became stable at a deviation of around 0.2 % from its nominal value at worst, and the voltage always stabilized at 1 p.u. Some values during the oscillations were measured above these limitations, but the extreme values were at all times reasonable. The report is written in Swedish. | |
