摘要： A magnetic device producing a small amount of leakage flux and capable of substantially eliminating the amount of leakage flux that escapes the magnetic core of the device. The device includes at least a portion of an electronic circuit that includes an interphase transformer arranged on a magnetic core. The reactor windings on each leg of the magnetic core are disposed in close proximity to each other and can be wound concentrically or in a bifilar fashion. The resulting combination of the magnetic core and windings provides a high degree of magnetic coupling between reactor windings disposed on the same leg and between reactor windings disposed on differing legs. The high degree of magnetic coupling substantially reduces the amount of leakage flux that can affect other metal objects proximate the magnetic device.

摘要： A speed setting system that generates a speed control command for controlling the rotational speed of a stall-controlled wind turbine of a wind-powered machine. The speed setting system generates the speed command as a function of performance variation of the wind turbine due to environmental and/or other factors. The speed setting system utilizes a performance-compensation term that is slowly adjusted to compensate for relatively long-term performance variation. In one example, the performance-compensation term is adjusted only when the current power output of the wind turbine is at least 80% of the rated output power to ensure the wind speed is sufficiently high.
摘要翻译：一种速度设定系统，其生成用于控制风力发电机的失速控制的风力涡轮机的转速的速度控制指令。速度设定系统由于环境和/或其他因素而产生作为风力涡轮机性能变化的函数的速度指令。速度设定系统使用缓慢调整的性能补偿项来补偿相对长期的性能变化。在一个示例中，仅当风力涡轮机的当前功率输出为额定输出功率的至少80％以确保风速足够高时才调整性能补偿项。

摘要： Systems and methods for reducing dynamic loading in an idled wind power unit include sensing at least one parameter indicative of dynamic loading and executing a reduced torque brake mode, which may comprise a controlled brake and brake-release sequence, with the turbine braking system when the sensed parameter exceeds a selected value. The reduced torque brake mode absorbs energy and reduces dynamic loading thereby.

摘要： A control system (20) for a power converter (22) designed to convert DC power from a source (30) such as a battery, flywheel or fuel cell into AC power. The control system includes an impedance current regulator (106) for providing an impedance current signal to a summing unit (110) where it may be combined with real and reactive current command signals provided from respective sources (62, 64). The resultant current signal provided by the summing unit is provided to a voltage correction unit (112) that uses the resultant current signal in developing a correction voltage signal provided to the power converter. The correction voltage signal contains information used by the power converter in adjusting the real and reactive currents in its output AC power based on the ability of the AC power network to accept changes in current. Multiple power converters having the control system of the present invention may be connected in parallel to a single AC load or multiple AC loads, without the need for a separate control system interconnecting the power converters. The control system may be advantageously incorporated into a distributed generation network and in uninterruptible power systems, whether or not such systems are included in a distributed generation network.

摘要： A power converter module for use alone or with other modules in a multiphase power converter. The power converter module has an enclosure that surrounds internal components to prevent radiation of electromagnetic energy, which internal components also limit conduction of electromagnetic energy. The internal components include an EMI filter, a ripple filter, a power converter, and a control interface that communicates with a control system of a power conversion system. The control interface includes a memory that stores information related to the power converter modules so as to improve interchangability of similar power modules with the multiphase power converter.

摘要： Electromagnetic rotary machines, such as electrical power generators and electric motors, that have one or more active portions modularized into a set of modules (128). Each of the modules (128) is secured to a support frame via a sliding - interlock system (224) that allows that module to be slidingly engaged with the support frame. In some embodiments, each module (128) can include an integrated coolant conduit (432) that carries a coolant to cool the active portion during operation. The modules (128) can each be self-contained in the respect that essentially all that needs to be done to form the active portion and corresponding portion of the cooling system is to install the modules and make any remaining electrical and coolant conduit connections.
