H02P 27/16
PCT/CL2016/000044UNIVERSIDAD TÉCNICA FEDERICO SANTA MARÍAPONTT OLIVARES, Jorge Antoni
The invention relates to a method and system for controlling a synchronous machine by means of a multi-pulse cyclo-converter actuated by means of predictive control, the method comprising: acquiring the variables of state associated with the system, at the present moment or a sample moment k, which include the reference currents for the internal current loop, in any coordinate system, whether d and q, abc or alpha-beta, the rotor speed wr, and the rotor angle θr; establishing all the possible future states on the basis of 64 volts that can be applied by the multi-pulse cyclo-converter to the synchronous machine, each of the 64 volts that can be applied being associated with a machine of admissible conduction states for each thyristor bridge of the multi-pulse cyclo-converter, according to a predetermined table of states; evaluating a cost function, it being established as a priority that currents d and q, abc or alpha-beta through the stator are equal to the reference currents; defining a maximum admissible value for currents d and q, abc or alpha-beta through the stator; considering in the cost function the inability to jump from one conduction state to another, depending on the entry voltage for each of the bridges in question; and applying trigger signals, the trigger signals being sent to the various thyristors corresponding to the admissible conduction case related to a lower value in the cost function, once the different cases shown in the predetermined table of states have been evaluated.

PCT/CL2016/000039JARA VARGAS, HugoJARA VARGAS, Hugo
The invention relates to a parabolic device for concentrating solar radiation, which allows the distribution of solar radiation per unit of area to be optimised, reducing the number of solar concentrators necessary to supply thermal energy in industrial processes, especially in mining. The device is formed from two main elements: a concentrator unit that includes three reflective surfaces, section a, section b and section c formed between points (1), (2), (3) and (4), allowing solar radiation to be reflected on two points (optical focuses), thereby enabling the volumetric flow of heated liquid to be doubled, points (1), (2), (3) and (4) being formed by placing parabola 1 on top of parabola 2, on the same axis, and sections a, b and c being covered by stainless steel mirror; and a support structure located at the centre of each end of the unit and formed by two rings (5) and (7) joined together by means of soldering to a metallic square profile (6). The support structure gives rigidity and acts as the support base for the designated element for capturing the solar radiation concentrated on the focuses.
