摘要： This invention relates to a method and a power plant controller arranged to carry out the method. The method is on an intelligent dispatching of the power production to wind turbines and optional compensation equipment of a wind power plant, as the power producing units of a wind power plant. The invention relates to a case where the requested produced power is less than the total capacity of the power plant, and the invention relates to utilizing this situation to dispatch set points to the wind turbines and the compensation equipment in a flexible way. This flexibility may increase the wind turbines' life time, help in scheduling maintenance and expand the electrical operating range of the wind power plant. The determination of the set points on active and reactive power is a combined determination of both set points for each of the energy producing units of the wind power plant.

摘要： An alternator has a field coil that produces a magnetic field which induces electricity in a coil arrangement. A field coil excitation system includes a generator with an output coil assembly for producing alternating electricity. A rectifier converts the alternating electricity into voltage and direct current at two nodes. A capacitor, between the nodes, has capacitance that forms a resonant circuit with inductance of the output coil assembly. Due to that resonant circuit, the voltage and direct current oscillate in a predefined phase relationship. A switch and the field coil are connected in series between the nodes. A controller renders the switch conductive for a time period specified by a received control signal. The switch is rendered non-conductive at the first occurrence of a minimum current level after the time period ends. The predefined phase relationship enables the minimum current level to be detected by sensing the voltage.

摘要： According to the present invention, use is made of a drag-type blade in which the blade is constituted vertically and in multiple blocks while the inside thereof is formed so as to have an overlapping region, thereby achieving an aerodynamic characteristic whereby there is a large initial torque for rotating the blade of the wind energy electricity generator from the stationary state such that the rotational moment is increased. On the outside thereof, use is made of airfoil-type blades, thereby obtaining rapid rotational acceleration with tip-speed ratio no less than 1.0 and effecting wind energy electricity generation even with a low wind velocity regardless of the wind direction, and thus the present invention is economic and can be installed at low cost unaffected by place or position and is environmentally friendly while nevertheless being able to effect highly efficient wind energy electricity generation.
