Abstract:
The invention relates to a method for controlling power flow within a wind park system (100) for power transmission to a main power grid (90), the wind park system (100) comprising two or more parallel- connected island wind park grids. The method comprises the steps of: controlling a first voltage source converter (10) as a swing bus in frequency control, the frequency control comprising controlling frequency to a steady state reference operating point for operating points within a power dead band and by means of frequency droop control when exceeding an end point of the power dead band, and controlling at least a second voltage source converter (20), (30), (40) in power control, the power control comprising controlling power flow to a steady state reference operating point for operating points within a frequency dead band and by means of power droop control when exceeding an end point of the frequency dead band. The invention also relates to controllers, computer programs and computer program products.

Abstract:
Method and sensing module for sensing pollution of outside air. The sensing module (1) comprises an electro chemical sensing element (3), and a processor (2). A sensing module output signal is provided based on the measurement signal and a baseline signal level. The baseline signal level is adapted depending on two threshold levels (13-15), A pollution concentration value is determined from the measurement signal and a classification level of air pollution is provided as sensing module output signal. A classification level is determined using a plurality of classification threshold values and the pollution concentration value. The plurality of classification threshold values are dynamically adjustable.

Abstract:
The read latency caused by job start preparation of a future job is at least partly hidden within the current job by reading information for job start preparation of the future job integrated with the execution of the current job. Instructions for job start preparation are preferably instrumented (701) into the current job and executed (702), whenever possible, in parallel with the instructions of the current job. The integrated job start preparation may include table look-ups, register file updating, instruction fetching and preparation. If the scheduled job order is allowed to change during execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution of the next job and take appropriate actions (704; 705, 706) dpending on the outcome of the test. In addition to reduced job start preparation time, unused slots in the instruction-parallel execution of the current job may be filled up by the added read instructions, thus providing more efficient utilization of the multiple functional execution units of the processor.
Abstract:
Method for recovery in a furnace for producing aluminium by melting electrolysis of alumina. The furnace gases are passed through a bed (23) of alumina while the bed being fluidized around a tube coil (25). Then, heat exchange takes place between the furnace gases and an external fluid passing through the tube coil, for recovering heat energy in the furnace gases.
