摘要： A controlled frequency generating system (CFG) may be constructed with a main generator and an exciter driven by a common shaft. Excitation power may be provided from the common shaft; as distinct from prior-art systems which may require independent excitation power sources. While controlling the output voltage and frequency of the main generator, the bi-directional controller extracts power from a main generator output and may supply the extracted power to supplement excitation power when needed at certain rotational speeds. The controller may extract power from the exciter when, at other rotational speeds, the exciter produces excess power. The extracted excess power may be delivered to the output of the main generator to maintain a desired level of output power at a desired frequency, irrespective of speed of rotation of the CFG.

摘要： Control features for a wind turbine that control the turbine over a range of wind speeds and under triggering conditions with reduced noise, cost, and reliability issues associated with other such controls. Control is accomplished via control electronics, which adjust the torque produced by the electrical output generation device (e.g., alternator) within the wind turbine. During normal operation, torque is adjusted for optimum aerodynamic performance and maximum output of power. In winds above rated power, the control circuit regulates torque to lower aerodynamic performance, as necessary to maintain desired power level output. In triggering conditions, such as during simultaneous control circuit failure and loss of some portion of the electrical output generation device in extreme winds, wind turbine control is accomplished by increasing torque (e.g., via a separate controller) from the electrical output generation device via shorting of windings, so as to cause retardation of blade rotation.

摘要： When a wind velocity sensor detects a wind velocity higher than a predetermined level, a timer device starts a waiting timer function during an operation timer period shorter than the waiting timer period. After the waiting timer period is over, the waiting timer function is switched to an operation timer function, and a switching relay switches a generator to a motor only during an operation timer period. Then, a driving circuit performs a start assisting rotation. After the operation timer period is over, the waiting timer period re-starts. This process is repeated. When during this period, the number of rotations of a rotor monitored by a rotation number measuring device, based on the output voltage Vm of a three-phase conduction coil exceeds a predetermined number of rotations, the charging of a battery by a three-phase generator is started.
