摘要： Vibrations at harmonic frequencies are reduced by injecting harmonic balancing signals into the armature of a linear motor/alternator coupled to a Stirling machine. The vibrations are sensed to provide a signal representing the mechanical vibrations. A harmonic balancing signal is generated for selected harmonics of the operating frequency by processing the sensed vibration signal with adaptive filter algorithms of adaptive filters for each harmonic. Reference inputs for each harmonic are applied to the adaptive filter algorithms at the frequency of the selected harmonic. The harmonic balancing signals for all of the harmonics are summed with a principal control signal. The harmonic balancing signals modify the principal electrical drive voltage and drive the motor/alternator with a drive voltage component in opposition to the vibration at each harmonic.

摘要： A wind power generation control device which controls a wind power generator using a wind turbine blade having a fixed pitch angle is provided. The wind power generation control device which controls the wind power generator in which an output current value outputted by the wind power generator is detected, an output voltage value outputted by the wind power generator is detected, a rotational speed of the wind turbine blade is detected, and on the basis of the detected output current value at the current time, the detected output voltage value at the current time, and the detected rotational speed at the current time, output power at the rotational speed at the current time is calculated, and on the basis of the calculated output power and blade aerodynamic properties, which are properties inherent to the wind turbine blade, the wind power generator is controlled so that an optimal amount of power corresponding to the wind speed can be efficiently obtained in a relatively low wind speed region and a wind power generation control method for controlling the wind power generator are provided.

摘要： The present invention provides a method of operating a wind turbine including a generator (4) that provides variable voltage at variable frequency and has a stator and a rotor. The wind turbine includes a turbine assembly (2) having at least one blade for rotating the rotor of the generator (4), and a power converter that interfaces the generator (4) to a supply network (NETWORK) operating at nominally fixed voltage and nominally fixed frequency. The power converter includes a generator bridge (10) electrically connected to the stator of the generator (4) and a network bridge (14). A dc link (12) is connected between the generator bridge (10) and the network bridge (14). A filter (16) having network terminals is connected between the network bridge (14) and the supply network. A first controller (18) is provided for controlling the operation of the semiconductor power switching devices of the generator bridge (14). Similarly, a second controller (46) is provided for controlling the operation of the semiconductor power switching devices of the network bridge (14). In response to a change in wind speed (e.g. an increasing or decreasing wind speed) the method comprises the steps of: (i) controlling the second active rectifier/inverter (14) to change the level of power exported out of the dc link (12) such that the dc link voltage changes from a desired level, and (ii) controlling the first active rectifier/inverter (10) to import sufficient current into the dc link (12) through the generator bridge (10) from the generator (4) to restore the dc link voltage to the desired level.

摘要： The electric power system comprises a three phase (L1, L2, L3) AC generator (500) comprising a stator (200) with a stator winding (220), a prime mover (600) driving the generator and being operated in a first rotation speed range extending from 60% of the nominal rotation speed to a maximum rotation speed, a rectifier (700) converting a three phase AC output voltage of the generator into a DC voltage, and a main controller (800). A connection arrangement (550) is further provided for switching the connection of the stator winding (220) of the generator (500) between a star connection (S1) and a delta connection (D1). A first rotation speed (RS1) and a second rotation speed (RS2) is provided within the first rotation speed range. The stator winding is switched into the star connection when the rotation speed of the generator is increasing and reaches the first rotation speed value (RS1) and into the delta connection when the rotation speed of the generator is decreasing and reaches the second rotation speed value (RS2).
