摘要： A power generator includes a magnetic pole rotor in which a plurality of N magnetic pole cores and S magnetic pole cores are arranged alternately at regular intervals and that is rotatably supported, stator coils that oppose the magnetic pole rotor and are wound round pole portions of poles of stator poles so as to generate AC power, full-wave rectifying circuits 18 for respective stator coils, and smoothing circuits that are connected to the output sides of the respective full-wave rectifying circuits. The power generator is so structured as to convert multiphase AC generated electric power into DC electric power. Further, line ends of positive (+) poles at the output side of the smoothing circuits are connected to the input side of rectifiers that make only current in the forward direction pass through, and the output side (+) line ends of the rectifiers are connected to a (+) combination line.

摘要： In a control system for controlling a power generator based on a command value associated with a control parameter, a receiver receives the command signal, a detector detects the command value included in the received command signal, and a determiner determines whether a duration of the detected command value being invariant within a predetermined range exceeds a predetermined allowed duration. In the control system, a controller controls an output of the power-generator based on a predetermined default value within the predetermined range in place of the command value when it is determined that the duration of the detected command value being invariant within the predetermined range exceeds the predetermined allowed duration.

摘要： The present invention provides a power converter that can be used to interface a generator (4) that provides variable voltage at variable frequency to a supply network operating at nominally fixed voltage and nominally fixed frequency and including features that allow the power converter to remain connected to the supply network and retain control during supply network fault and transient conditions. 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). The first controller (18) uses a dc link voltage demand signal (VDC_GEN*) indicative of a desired dc link voltage to control the semiconductor power switching devices of the network bridge (10) to achieve the desired level of dc link voltage that corresponds to the dc link voltage demand signal (VDC_GEN*). The second controller (46) uses a power demand signal (P*) indicative of the level of power to be transferred from the dc link to the supply network through the network bridge (14), and a voltage demand signal (VTURB*) indicative of the voltage to be achieved at the network terminals of the filter (16) to control the semiconductor power switching devices of the network bridge (14) to achieve the desired levels of power and voltage that correspond to the power and voltage demand signals (P* and VTURB*).

摘要： A wind turbine includes an asynchronous generator having a rotor and a stator, means for determining an actual torque-speed curve of the generator, means for determining an actual grid frequency, and means for determining a shifted torque-speed curve in response to the determined actual grid frequency if the determined actual grid frequency is higher than a predetermined upper frequency limit or lower than a predetermined lower frequency limit. The means for determining a shifted torque-speed curve is further adapted to determine the shifted torque-speed curve such that an increase in the rotor voltage of said generator rotor is counteracted when shifting the actual torque-speed curve to the shifted torque-speed curve. The wind turbine further includes means for shifting the actual torque-speed curve of the generator to the shifted torque-speed curve.
